Bug#20028 (Function with select return no data)
Before this change, THD::abort_on_warning was set in sp_head::execute,
causing Stored Procedures, Stored Functions and Triggers to treat warnings
as errors when executing in a strict SQL_MODE.
After this change, THD::abort_on_warning is set in process_triggers in
sql/sql_trigger.cc, which only affects triggers. Only INSERT and UPDATE
triggers can elevate the abort_on_warning flag, which does not affect
This fix is a revision of the change done for 6951, it produces the
same results for the INSERT and UPDATE triggers in strict mode, while not
causing side effects in DELETE triggers, Stored Procedures or Stored
Functions, which -- according to the definition of a STRICT mode -- should
not produre errors when no insert or update is performed.
We are planning to rebase mysql to 5.0.45 (or later) in RHEL 5.2. That should take care of this bug, along
with boatloads of others ...
Fixed in RHEL 5.2 update.
