Events: crash with procedure which alters events with function Post-review CS This fix also changes the handling of KILL command combined with subquery. It changes the error message given back to "not supported", from parse error. The error for CREATE|ALTER EVENT has also been changed to generate "not supported yet" instead of parse error. In case of a SP call, the error is "not supported yet". This change cleans the parser from code which should not belong to there. Still LEX::expr_allows_subselect is existant because it simplifies the handling of SQLCOM_HA_READ which forbids subselects. mysql-test/r/events_bugs.result: update resut mysql-test/r/events_grant.result: update result mysql-test/r/kill.result: the error message has been changed for KILL mysql-test/t/events_bugs.test: Update old tests with the new emitted error Add a test case for BUG#22830 Events: crash with procedure which alters events with function mysql-test/t/events_grant.test: add ORDER BY clause to keep the result deterministic. mysql-test/t/kill.test: use name of the error, and change the error from parse error, to not supported sql/sql_lex.cc: Add an auxiliary function that checks whether SP and/or tables are used in the statement. This function is helpful for statements that cannot handle subqueries ans SP calls. Adding out of the parser cleans the latter of handling of special cases and letting it do its job of parsing. sql/sql_lex.h: helper function to check whether a table or SP was used sql/sql_parse.cc: Use LEX::table_or_sp_used() for SQLCOM_CREATE_EVENT, SQLCOM_ALTER_EVENT and SQLCOM_KILL. SQLCOM_DROP event does not use `expr` rule and thus a check is not needed. sql/sql_yacc.yy: Remove usage of LEX::expr_allows_subselect for CREATE|ALTER EVENT and KILL. There is only one left occurence - SQLCOM_HAREAD, but it adds one table to the list of tables
