"Access compatibility" syntax The "wild" "DELETE FROM table_name.* ... USING ..." syntax for multi-table DELETE statements is documented but it was lost in the fix for the bug 30234. The table_ident_opt_wild parser rule has been added to restore the lost syntax. mysql-test/r/delete.result: Test case for bug #53034. mysql-test/t/delete.test: Test case for bug #53034. sql/sql_yacc.yy: Bug #53034: Multiple-table DELETE statements not accepting "Access compatibility" syntax The table_ident_opt_wild parser rule has been added to restore the lost syntax. Note: simple extending of table_ident with opt_wild in the table_alias_ref rule is not acceptable, because a) it adds one conflict more and b) this conflict resolves in the inappropriate way.
