  • Revision #804b00e 2016-05-24 18:23:18 +0400
    • An sql_yacc.yy clean-up - Moving opt_union_order_or_limit inside union_opt, as it's not used in other places any more. - Changing union_opt to have no type. Earlier (before all MDEV-8909 dependency tasks) it had the <num> type, and it's return value was used to generate errors. Now union_opt does not need a return value because the grammar disallows ORDER and LIMIT clauses in wrong context.
