When invoking st_distance_sphere with unexpected geometries, the error
message now given is:
ERROR HY000: Internal error: Point or multipoint geometries expected
This commit fixes a few formatting issues in the affected function.
add_special_frame_cursors() did not check the return
value offset_func->fix_fields(). It can return an error
if the data type does not support the operator "minus".
Field_blob::store() has special code for GROUP_CONCAT temporary table
(to store blob values in Blob_mem_storage - this prevents them
from being freed/overwritten when a next row is read).
Field_geom and Field_blob_compressed inherit from Field_blob but they
have their own ::store() method without this special Blob_mem_storage
support.
Considering that non-grouping CONCAT() of such fields converts
them to plain BLOB, let's do the same for GROUP_CONCAT. To do it,
Item_func_group_concat::setup will signal that it's creating
a temporary table for GROUP_CONCAT, and Field_blog::make_new_field()
override will create base Field_blob when under group concat.
Updated tests: cases with bugs or which cannot be run
with the cursor-protocol were excluded with
"--disable_cursor_protocol"/"--enable_cursor_protocol"
Fix for v.10.5
Fails with:
query 'select ST_AsWKT(GeometryCollection(Point(44, 6), @g))' failed:
ER_ILLEGAL_VALUE_FOR_TYPE (1367): Illegal non geometric '@`g`' value
found during parsing
Tests with checking metadata or that cannot be run with
the view-protocol are excluded from --view-protocol.
For tests that do not allow the use of an additional connection,
the util connection is disabled with "--disable_service_connection".
Also cases with bugs for --view-protocol are disabled.
Now INSERT, UPDATE, ALTER statements involving incompatible data type pairs, e.g.:
UPDATE TABLE t1 SET col_inet6=col_int;
INSERT INTO t1 (col_inet6) SELECT col_in FROM t2;
ALTER TABLE t1 MODIFY col_inet6 INT;
consistently return an error at the statement preparation time:
ERROR HY000: Illegal parameter data types inet6 and int for operation 'SET'
and abort the statement before starting interating rows.
This error is the same with what is raised for queries like:
SELECT col_inet6 FROM t1 UNION SELECT col_int FROM t2;
SELECT COALESCE(col_inet6, col_int) FROM t1;
Before this change the error was caught only during the execution time,
when a Field_xxx::store_xxx() was called for the very firts row.
The behavior was not consistent between various statements and could do different things:
- abort the statement
- set a column to the data type default value (e.g. '::' for INET6)
- set a column to NULL
A typical old error was:
ERROR 22007: Incorrect inet6 value: '1' for column `test`.`t1`.`a` at row 1
EXCEPTION:
Note, there is an exception: a multi-row INSERT..VALUES, e.g.:
INSERT INTO t1 (col_a,col_b) VALUES (a1,b1),(a2,b2);
checks assignment compability at the preparation time for the very first row only:
(col_a,col_b) vs (a1,b1)
Other rows are still checked at the execution time and return the old warnings
or errors in case of a failure. This is done because catching all rows at the
preparation time would change behavior significantly. So it still works
according to the STRICT_XXX_TABLES sql_mode flags and the table transaction ability.
This is too late to change this behavior in 10.7.
There is no a firm decision yet if a multi-row INSERT..VALUES
behavior will change in later versions.
