BUG#11758263 50440: MARK UNORDERED UPDATE WITH AUTOINC UNSAFE
Problem: Statements that write to tables with auto_increment columns
based on the selection from another table, may lead to master
and slave going out of sync, as the order in which the rows
are retrived from the table may differ on master and slave.
Solution: We mark writing to a table with auto_increment table
as unsafe. This will cause the execution of such statements to
throw a warning and forces the statement to be logged in ROW if
the logging format is mixed.
Changes:
1. All the statements that writes to a table with auto_increment
column(s) based on the rows fetched from another table, will now
be unsafe.
2. CREATE TABLE with SELECT will now be unsafe.
sql/share/errmsg-utf8.txt:
Added new Warning messages
sql/sql_base.cc:
created a new function that checks for select + write on a autoinc table
made all such statements to be unsafe.
sql/sql_parse.cc:
made create autoincremnet tabble + select unsafe
