DBUG_EXECUTE_IF macro. The usage of the former caused breakage in other
trees as it got removed from the dbug library.
sql/sql_base.cc:
Rework code to remove unreliable usage of _db_script_keyword_.
The problem is that when statement-based replication was enabled,
statements such as INSERT INTO .. SELECT FROM .. and CREATE TABLE
.. SELECT FROM need to grab a read lock on the source table that
does not permit concurrent inserts, which would in turn be denied
if the source table is a log table because log tables can't be
locked exclusively.
The solution is to not take such a lock when the source table is
a log table as it is unsafe to replicate log tables under statement
based replication. Furthermore, the read lock that does not permits
concurrent inserts is now only taken if statement-based replication
is enabled and if the source table is not a log table.
include/thr_lock.h:
Introduce yet another lock type that my get upgraded depending
on the binary log format. This is not a optimal solution but
can be easily improved later.

sql/lock.cc:
Assert that TL_READ_DEFAULT is not a real lock type.
sql/mysql_priv.h:
Export new function.
sql/mysqld.cc:
Remove using_update_log.
sql/sql_base.cc:
Introduce function that returns the appropriate read lock type
depending on how the statement is going to be replicated. It will
only take a TL_READ_NO_INSERT log if the binary is enabled and the
binary log format is statement-based and the table is not a log table.
sql/sql_parse.cc:
Remove using_update_log.
sql/sql_update.cc:
Use new function to choose read lock type.
sql/sql_yacc.yy:
The lock type is now decided at open_tables time. This old behavior was
actually misleading as the binary log format can be dynamically switched
and this would not change for statements that have already been parsed
when the binary log format is changed (ie: prepared statements).
columns data types
The "SELECT @lastId, @lastId := Id FROM t" query returns
different result sets depending on the type of the Id column
(INT or BIGINT).
Note: this fix doesn't cover the case when a select query
references an user variable and stored function that
updates a value of that variable, in this case a result
is indeterminate.
The server uses incorrect assumption about a constantness of
an user variable value as a select list item:
The server caches a last query number where that variable
was changed and compares this number with a current query
number. If these numbers are different, the server guesses,
that the variable is not updating in the current query, so
a respective select list item is a constant. However, in some
common cases the server updates cached query number too late.
The server has been modified to memorize user variable
assignments during the parse phase to take them into account
on the next (query preparation) phase independently of the
order of user variable references/assignments in a select
item list.

mysql-test/t/user_var.test:

sql/item_func.cc:
An update of entry and update_query_id variables has been
moved from Item_func_set_user_var::fix_fields() to a separate
method, Item_func_set_user_var::set_entry().
sql/item_func.h:
1. The Item_func_set_user_var::set_entry() method has been
added to update Item_func_set_user_var::entry.
2. The Item_func_set_user_var::entry_thd field has beend
added to update Item_func_set_user_var::entry only when
needed.
sql/sql_base.cc:
Fix: setup_fiedls() calls Item_func_set_user_var::set_entry()
for all items from the thd->lex->set_var_list before the first
call of ::fix_fields().
sql/sql_lex.cc:
The lex_start function has been modified to reset
the st_lex::set_var_list list.
sql/sql_lex.h:
New st_lex::set_var_list field has been added to
memorize all user variable assignments in the current
select query.
sql/sql_yacc.yy:
The variable_aux rule has been modified to memorize
in-query user variable assignments in the
st_lex::set_var_list list.
This patch also fixes bugs 36963 and 35600.
- In many places a view was confused with an anonymous derived
table, i.e. access checking was skipped. Fixed by introducing a
predicate to tell the difference between named and anonymous
derived tables.
- When inserting fields for "SELECT * ", there was no
distinction between base tables and views, where one should be
made. View privileges are checked elsewhere.

representation of these properties.
- Implementing --base64-format=decode-rows, to display
SQL-alike decoded row events without their BINLOG statements.
- Adding --base64-format=decode-rows into tests when
calling mysqlbinlog to avoid non-deterministic results
- Removing resetting of last_table_id in "RESET MASTER",
which appeared to be dangerous.
Implementing -v command line parameter to mysqlbinlog

When flushing tables, there were a slight chance that the flush was occuring
between processing of two table map events. Since the tables are opened
one by one, it might result in that the tables were not valid and that sub-
sequent locking of tables would cause the slave to crash.
The problem is solved by opening and locking all tables at once using
simple_open_n_lock_tables(). Also, the patch contain a change to open_tables()
so that pre-locking only takes place when the trg_event_map is not zero, which
was not the case before (this caused the lock to be placed in thd->locked_tables
instead of thd->lock since the assumption was that triggers would be called
later and therefore the tables should be pre-locked).

WL#4165 Prepared statements: validation
WL#4166 Prepared statements: automatic re-prepare
Fixes
Bug#27430 Crash in subquery code when in PS and table DDL changed after PREPARE
Bug#27690 Re-execution of prepared statement after table was replaced with a view crashes
Bug#27420 A combination of PS and view operations cause error + assertion on shutdown
The basic idea of the patch is to keep track of table metadata between
prepared statement prepare and execute. If some table used in the statement
has changed, the prepared statement is re-prepared before execution.
See WL#4165 and WL#4166 contents and comments in the code for details
of the implementation.

sql/item.cc:
Implement Item_param "copy" functionality, used at re-prepare of
a prepared statement.
We copy the type of the original parameter, and move the assigned value,
if any. Sic, the value is "moved", since it can be quite big --
e.g. in case we deal with a LONG DATA parameter.
It's essential to move the value from the old parameter since
at the time of re-prepare the client packet with the necessary information
may be not available.
sql/item.h:
Declare a new method used for reprepare.
sql/my_decimal.h:
Implement "swap()" functionality of class my_decimal to be
able to easily swap two decimal values.
sql/mysql_priv.h:
Declare enum_metadata_type.
sql/mysqld.cc:
Implement a status variable for the number of reprepared statements.
sql/sql_base.cc:
Implement metadata version validation.
sql/share/errmsg.txt:
Add two new error messages: ER_NEED_REPREPARE and ER_PS_REBIND.
The first error (theoretically) never reaches the user.
It is issued by the metadata validation framework when a metadata version
has changed between prepare and execute. Later on it's intercepted
and the statement is automatically re-prepared. Only if the error
has occurred repeatedly MAX_REPREPARE_ATTEMTS (3) times do we
return it to the user.
The second error is issued when after re-prepare we discover
that the metadata we sent over to the client using the binary
protocol differs drammatically from the new result set metadata
that the reprepared statement produces (e.g. number of result
set columns is different).
sql/sql_class.cc:
Implement metadata version validation framework.
sql/sql_class.h:
Declarations for metadata version validation framework.
sql/sql_parse.cc:
Mark commands for which we must invalidate and reprepare a prepared
statement when metadata has changed.
sql/sql_prepare.cc:

and re-prepare).
sql/table.h:
Implement metadata validation.

The bool data type was redefined to BOOL (4 bytes on windows).
Removed the #define and fixed some of the warnings that were uncovered
by this.
Note that the fix also disables 2 warnings :
4800 : 'type' : forcing value to bool 'true' or 'false' (performance warning)
4805: 'operation' : unsafe mix of type 'type' and type 'type' in operation
These warnings will be handled in a separate bug, as they are performance related or bogus.

The idea of the fix is to ensure that we always commit the current

sql/sql_delete.cc:
Remove wrong and now redundant calls to ha_autocommit_or_rollback.
The transaction is committed in one place, at the end of the statement.
Remove calls to mysql_unlock_tables, since some engines count locks
and commit statement transaction in unlock_tables(), which essentially
equates mysql_unlock_tables to ha_autocommit_or_rollback.
Previously it was necessary to unlock tables soon because we wanted
to avoid sending of 'ok' packet to the client under locked tables.
This is no longer necessary, since OK packet is also sent from one place
at the end of transaction.
sql/sql_do.cc:

statement before this happens. Otherwise the statement will be committed,
and not rolled back in the end.
sql/sql_insert.cc:
Remove wrong and now redundant calls to ha_autocommit_or_rollback.
The transaction is committed in one place, at the end of the statement.
Remove calls to mysql_unlock_tables, since some engines count locks
and commit statement transaction in unlock_tables(), which essentially
equates mysql_unlock_tables to ha_autocommit_or_rollback.
Previously it was necessary to unlock tables soon because we wanted
to avoid sending of 'ok' packet to the client under locked tables.
This is no longer necessary, since OK packet is also sent from one place
at the end of transaction.
sql/sql_load.cc:
Remove wrong and now redundant calls to ha_autocommit_or_rollback.
The transaction is committed in one place, at the end of the statement.
Remove calls to mysql_unlock_tables, since some engines count locks
and commit statement transaction in unlock_tables(), which essentially

sql/sql_parse.cc:
Implement optimisation of read-only transactions: bypass 2-phase
commit for them.
Always commit statement transaction before commiting the global one.
Fix an unrelated crash in check_table_access, when called from
information_schema.
sql/sql_partition.cc:
Partitions commit at the end of a DDL operation.
Make sure that send_ok() is done only if the commit has succeeded.
sql/sql_table.cc:
Use ha_autocommit_or_rollback and end_active_trans everywhere.
Add end_trans to mysql_admin_table, so that it leaves no pending
transaction.
sql/sql_udf.cc:

pre-locking.
The crash was caused by an implicit assumption in check_table_access() that
table_list parameter is always a part of lex->query_tables.
When iterating over the passed list of tables, check_table_access() used
to stop only when lex->query_tables_last_not_own was reached.
In case of pre-locking, lex->query_tables_last_own is not NULL and points
to some element of lex->query_tables. When the parameter
of check_table_access() was not part of lex->query_tables, loop invariant
could never be violated and a crash would happen when the current table
pointer would point beyond the end of the provided list.
The fix is to change the signature of check_table_access() to also accept
a numeric limit of loop iterations, similarly to check_grant(), and
supply this limit in all places when we want to check access of tables
that are outside lex->query_tables, or just want to check access to one table.

The problem is that some DDL statements (ALTER TABLE, CREATE
TRIGGER, FLUSH TABLES, ...) when under LOCK TABLES need to
momentarily drop the lock, reopen the table and grab the write
lock again (using reopen_tables). When grabbing the lock again,
reopen_tables doesn't pass a flag to mysql_lock_tables in
order to ignore the impending global read lock, which causes a
assertion because LOCK_open is being hold. Also dropping the
lock must not signal to any threads that the table has been
relinquished (related to the locking/flushing protocol).
The solution is to correct the way the table is reopenned
and the locks grabbed. When reopening the table and under
LOCK TABLES, the table version should be set to 0 so other
threads have to wait for the table. When grabbing the lock,
any other flush should be ignored because it's theoretically
a atomic operation. The chosen solution also fixes a potential
discrepancy between binlog and GRL (global read lock) because
table placeholders were being ignored, now a FLUSH TABLES WITH
READ LOCK will properly for table with open placeholders.
It's also important to mention that this patch doesn't fix
a potential deadlock if one uses two GRLs under LOCK TABLES
concurrently.

cause ROLLBACK of statement", part 1. Review fixes.
Do not send OK/EOF packets to the client until we reached the end of
the current statement.
This is a consolidation, to keep the functionality that is shared by all
SQL statements in one place in the server.
Currently this functionality includes:
- close_thread_tables()
- log_slow_statement().
After this patch and the subsequent patch for Bug#12713, it shall also include:
- ha_autocommit_or_rollback()
- net_end_statement()
- query_cache_end_of_result().
In future it may also include:
- mysql_reset_thd_for_next_command().
include/mysql_com.h:
Rename now unused members of NET: no_send_ok, no_send_error, report_error.
These were server-specific variables related to the client/server
protocol. They have been made obsolete by this patch.
Previously the same members of NET were used to store the error message
both on the client and on the server.
The error message was stored in net.last_error (client: mysql->net.last_error,
server: thd->net.last_error).
The error code was stored in net.last_errno (client: mysql->net.last_errno,
server: thd->net.last_errno).
The server error code and message are now stored elsewhere
(in the Diagnostics_area), thus NET members are no longer used by the
server.
Rename last_error to client_last_error, last_errno to client_last_errno
to avoid potential bugs introduced by merges.
include/mysql_h.ic:
Update the ABI file to reflect a rename.
Renames do not break the binary compatibility.
libmysql/libmysql.c:
Rename last_error to client_last_error, last_errno to client_last_errno.
This is necessary to ensure no unnoticed bugs introduced by merged
changesets.
Remove net.report_error, net.no_send_ok, net.no_send_error.
libmysql/manager.c:
Rename net.last_errno to net.client_last_errno.
libmysqld/lib_sql.cc:
Rename net.last_errno to net.client_last_errno.
Update the embedded implementation of the client-server protocol to
reflect the refactoring of protocol.cc.
libmysqld/libmysqld.c:
Rename net.last_errno to net.client_last_errno.
mysql-test/r/events.result:
Update to reflect the change in mysql_rm_db(). Now we drop stored
routines and events for a given database name only if there
is a directory for this database name. ha_drop_database() and
query_cache_invalidate() are called likewise.
Previously we would attempt to drop routines/events even if database
directory was not found (it worked, since routines and events are stored
in tables). This fixes Bug 29958 "Weird message on DROP DATABASE if mysql.proc
does not exist".
The change was done because the previous code used to call send_ok()
twice, which led to an assertion failure when asserts against it were
added by this patch.
mysql-test/r/grant.result:
Fix the patch for Bug 16470, now FLUSH PRIVILEGES produces an error
if mysql.procs_priv is missing.
This fixes the assert that send_ok() must not called after send_error()
(the original patch for Bug 16470 was prone to this).
mysql-test/suite/rpl/r/rpl_row_tabledefs_2myisam.result:
Produce a more detailed error message.
mysql-test/suite/rpl/r/rpl_row_tabledefs_3innodb.result:

is never assigned twice per statement (see the comment in the code
when this can happen). We still do not clear thd->is_fatal_error and
thd->is_slave_error, which may lead to bugs, I consider the whole affair
as something to be dealt with separately.
sql/ha_partition.cc:
fatal_error() doesn't set an error by itself. Perhaps we should
remove this method altogether and instead add a flag to my_error
to set thd->is_fatal_error property.
Meanwhile, this change is a part of inspection made to the entire source
code with the goal to ensure that fatal_error()
is always accompanied by my_error().
sql/item_func.cc:
There is no net.last_error anymore. Remove the obsolete assignment.
sql/log_event.cc:
Use getters to access statement error status information.
sql/log_event_old.cc:
Use getters to access statement error status information.
sql/mysqld.cc:
Previously, if a continue handler for an error was found, my_message_sql()
would not set an error in THD. Since the current statement
must be aborted in any case, find_handler() had a hack to assign
thd->net.report_error to 1.
Remove this hack. Set an error in my_message_sql() even if the continue
handler is found. The error will be cleared anyway when the handler
is executed. This is one action among many in this patch to ensure the
invariant that whenever thd->is_error() is TRUE, we have a message in
thd->main_da.message().
sql/net_serv.cc:
Use a full-blown my_error() in net_serv.cc to report an error,
instead of just setting net->last_errno. This ensures the invariant that
whenever thd->is_error() returns TRUE, we have a message in
thd->main_da.message().
Remove initialization of removed NET members.
sql/opt_range.cc:
Use my_error() instead of just raising thd->net.report_error.
This ensures the invariant that whenever thd->is_error() returns TRUE,
there is a message in thd->main_da.message().
sql/opt_sum.cc:
Move invocation of fatal_error() right next to the place where
we set the error message. That makes it easier to track that whenever
fatal_error() is called, there is a message in THD.
sql/protocol.cc:
Rename send_ok() and send_eof() to net_send_ok() and net_send_eof()
respectively. These functions write directly to the network and are not
for use anywhere outside the client/server protocol code.
Remove the code that was responsible for cases when either there is
no error code, or no error message, or both.
Instead the calling code ensures that they are always present. Asserts
are added to enforce the invariant.
Instead of a direct access to thd->server_status and thd->total_warn_count
use function parameters, since these from now on don't always come directly
from THD.
Introduce net_end_statement(), the single-entry-point replacement API for
send_ok(), send_eof() and net_send_error().
Implement Protocol::end_partial_result_set to use in select_send::abort()
when there is a continue handler.
sql/protocol.h:
Update declarations.
sql/repl_failsafe.cc:
Use getters to access statement status information in THD.
Rename net.last_error to net.client_last_error.
sql/rpl_record.cc:
Set an error message in prepare_record() if there is no default
value for the field -- later we do print this message to the client.
sql/rpl_rli.cc:
Use getters to access statement status information in THD.
sql/slave.cc:
In create_table_from_dump() (a common function that is used in
LOAD MASTER TABLE SQL statement and COM_LOAD_MASTER_DATA), instead of hacks
with no_send_ok, clear the diagnostics area when mysql_rm_table() succeeded.
Update has_temporary_error() to work correctly when no error is set.
This is the case when Incident_log_event is executed: it always returns
an error but does not set an error message.
Use getters to access error status information.
sql/sp_head.cc:
Instead of hacks with no_send_error, work through the diagnostics area
interface to suppress sending of OK/ERROR packets to the client.
Move query_cache_end_of_result before log_slow_statement(), similarly
to how it's done in dispatch_command().
sql/sp_rcontext.cc:
Remove hacks with assignment of thd->net.report_error, they are not
necessary any more (see the changes in mysqld.cc).
sql/sql_acl.cc:
Use getters to access error status information in THD.
sql/sql_base.cc:
Access thd->main_da.sql_errno() only if there is an error. This fixes
a bug when auto-discovery, that was effectively disabled under pre-locking.
sql/sql_binlog.cc:
Remove hacks with no_send_ok/no_send_error, they are not necessary
anymore: the caller is responsible for network communication.
sql/sql_cache.cc:
Disable sending of OK/ERROR/EOF packet in the end of dispatch_command
if the response has been served from the query cache. This raises the
question whether we should store EOF packet in the query cache at all,
or generate it anew for each statement (we should generate it anew), but
this is to be addressed separately.
sql/sql_class.cc:
Implement class Diagnostics_area. Please see comments in sql_class.h
for details.
Fix a subtle coding mistake in select_send::send_data: when on slave,
an error in Item::send() was ignored.
The problem became visible due to asserts that the diagnostics area is
never double assigned.
Remove initialization of removed NET members.
In select_send::abort() do not call select_send::send_eof(). This is
not inheritance-safe. Even if a stored procedure continue handler is
found, the current statement is aborted, not succeeded.
Instead introduce a Protocol API to send the required response,
Protocol::end_partial_result_set().
This simplifies implementation of select_send::send_eof(). No need
to add more asserts that there is no error, there is an assert inside
Diagnostics_area::set_ok_status() already.
Leave no trace of no_send_* in the code.
sql/sql_class.h:
Declare class Diagnostics_area.
Remove the hack with no_send_ok from
Substatement_state.
Provide inline implementations of send_ok/send_eof.
Add commetns.
sql/sql_connect.cc:
Remove hacks with no_send_error.
Since now an error in THD is always set if net->error, it's not necessary
to check both net->error and thd->is_error() in the do_command loop.
Use thd->main_da.message() instead of net->last_errno.
Remove the hack with is_slave_error in sys_init_connect. Since now we do not
reset the diagnostics area in net_send_error (it's reset at the beginning
of the next statement), we can access it safely even after
execute_init_command.
sql/sql_db.cc:
Update the code to satisfy the invariant that the diagnostics area is never
assigned twice.
Incidentally, this fixes Bug 29958 "Weird message on DROP DATABASE if
mysql.proc does not exist".
sql/sql_delete.cc:
Change multi-delete to abort in abort(), as per select_send protocol.
Fixes the merge error with the test for Bug 29136
sql/sql_derived.cc:
Use getters to access error information.
sql/sql_insert.cc:
Use getters to access error information.
sql-common/client.c:
Rename last_error to client_last_error, last_errno to client_last_errno.
sql/sql_parse.cc:
Remove hacks with no_send_error. Deploy net_end_statement().
The story of COM_SHUTDOWN is interesting. Long story short, the server
would become on its death's door, and only no_send_ok/no_send_error assigned
by send_ok()/net_send_error() would hide its babbling from the client.
First of all, COM_QUIT does not require a response. So, the comment saying
"Let's send a response to possible COM_QUIT" is not only groundless
(even mysqladmin shutdown/mysql_shutdown() doesn't send COM_QUIT after
COM_SHUTDOWN), it's plainly incorrect.
Secondly, besides this additional 'OK' packet to respond to a hypothetical
COM_QUIT, there was the following code in dispatch_command():
if (thd->killed)
thd->send_kill_message();
if (thd->is_error()
net_send_error(thd);
This worked out really funny for the thread through which COM_SHUTDOWN
was delivered: we would get COM_SHUTDOWN, say okay, say okay again,
kill everybody, get the kill signal ourselves, and then attempt to say
"Server shutdown in progress" to the client that is very likely long gone.
This all became visible when asserts were added that the Diagnostics_area
is not assigned twice.
Move query_cache_end_of_result() to the end of dispatch_command(), since
net_send_eof() has been moved there. This is safe, query_cache_end_of_result()
is a no-op if there is no started query in the cache.
Consistently use select_send interface to call abort() or send_eof()
depending on the operation result.
Remove thd->fatal_error() from reset_master(), it was a no-op.
in hacks with no_send_error woudl save us
from complete breakage of the client/server protocol.
Consistently use select_send::abort() whenever there is an error,
and select_send::send_eof() in case of success.
The issue became visible due to added asserts.
sql/sql_partition.cc:
Always set an error in THD whenever there is a call to fatal_error().
sql/sql_prepare.cc:
Deploy class Diagnostics_area.
Remove the unnecessary juggling with the protocol in
Select_fetch_protocol_binary::send_eof(). EOF packet format is
protocol-independent.
sql/sql_select.cc:
Call fatal_error() directly in opt_sum_query.
Call my_error() whenever we call thd->fatal_error().
sql/sql_servers.cc:
Use getters to access error information in THD.
sql/sql_show.cc:
Use getters to access error information in THD.
Add comments.
Call my_error() whenever we call fatal_error().
sql/sql_table.cc:
Replace hacks with no_send_ok with the interface of the diagnostics area.
Clear the error if ENOENT error in ha_delete_table().
sql/sql_update.cc:
Introduce multi_update::abort(), which is the proper way to abort a
multi-update. This fixes the merge conflict between this patch and
the patch for Bug 29136.
sql/table.cc:
Use a getter to access error information in THD.
sql/tztime.cc:
Use a getter to access error information in THD.
The patch for Bug 26379 (Combination of FLUSH TABLE and
REPAIR TABLE corrupts a MERGE table) fixed this bug too.
However it revealed a new bug that crashed the server.
Flushing a merge table at the moment when it is between open
and attach of children crashed the server.
The flushing thread wants to abort locks on the flushed table.
It calls ha_myisammrg::lock_count() and ha_myisammrg::store_lock()
on the TABLE object of the other thread.
Changed ha_myisammrg::lock_count() and ha_myisammrg::store_lock()
to accept non-attached children. ha_myisammrg::lock_count() returns
the number of MyISAM tables in the MERGE table so that the memory
allocation done by get_lock_data() is done correctly, even if the
children become attached before ha_myisammrg::store_lock() is
called. ha_myisammrg::store_lock() will not return any lock if the
children are not attached.
This is however a change in the handler interface. lock_count()
can now return a higher number than store_lock() stores locks.
This is more safe than the reverse implementation would be.
get_lock_data() in the SQL layer is adjusted accordingly. It sets
MYSQL_LOCK::lock_count based on the number of locks returned by
the handler::store_lock() calls, not based on the numbers returned
by the handler::lock_count() calls. The latter are only used for
allocation of memory now.
No test case. The test suite cannot reliably run FLUSH between
lock_count() and store_lock() of another thread. The bug report
contains a program that can repeat the problem with some
probability.

This bug is actually two bugs in one, one of which is CREATE TRIGGER under
LOCK TABLES and the other is CREATE TRIGGER under LOCK TABLES simultaneous
to a FLUSH TABLES WITH READ LOCK (global read lock). Both situations could
lead to a server crash or deadlock.
The first problem arises from the fact that when under LOCK TABLES, if the
table is in the set of locked tables, the table is already open and it doesn't
need to be reopened (not a placeholder). Also in this case, if the table is
not write locked, a exclusive lock can't be acquired because of a possible
deadlock with another thread also holding a (read) lock on the table. The
second issue arises from the fact that one should never wait for a global
read lock if it's holding any locked tables, because the global read lock
is waiting for these tables and this leads to a circular wait deadlock.
The solution for the first case is to check if the table is write locked
and upgraded the write lock to a exclusive lock and fail otherwise for non
write locked tables. Grabbin the exclusive lock in this case also means
to ensure that the table is opened only by the calling thread. The second
issue is partly fixed by not waiting for the global read lock if the thread
is holding any locked tables.
The second issue is only partly addressed in this patch because it turned
out to be much wider and also affects other DDL statements. Reported as
