/*
|
|
mysql_create_table_no_lock can be called in one of the following
|
|
mutually exclusive situations:
|
|
|
|
- Just a normal ordinary CREATE TABLE statement that explicitly
|
|
defines the table structure.
|
|
|
|
- CREATE TABLE ... SELECT. It is special, because only in this case,
|
|
the list of fields is allowed to have duplicates, as long as one of the
|
|
duplicates comes from the select list, and the other doesn't. For
|
|
example in
|
|
|
|
CREATE TABLE t1 (a int(5) NOT NUL) SELECT b+10 as a FROM t2;
|
|
|
|
the list in alter_info->create_list will have two fields `a`.
|
|
|
|
- ALTER TABLE, that creates a temporary table #sql-xxx, which will be later
|
|
renamed to replace the original table.
|
|
|
|
- ALTER TABLE as above, but which only modifies the frm file, it only
|
|
creates an frm file for the #sql-xxx, the table in the engine is not
|
|
created.
|
|
|
|
- Assisted discovery, CREATE TABLE statement without the table structure.
|
|
|
|
These situations are distinguished by the following "create table mode"
|
|
values, where a CREATE ... SELECT is denoted by any non-negative number
|
|
(which should be the number of fields in the SELECT ... part), and other
|
|
cases use constants as defined below.
