only const tables The problem was caused by two shortcuts in the optimizer that are inapplicable in the ROLLUP case. Normally in a case when only const tables are involved in a query, DISTINCT clause can be safely optimized away since there may be only one row produced by the join. Similarly, we don't need to create a temporary table to resolve DISTINCT/GROUP BY/ORDER BY. Both of these are inapplicable when the WITH ROLLUP modifier is present. Fixed by disabling the said optimizations for the WITH ROLLUP case. mysql-test/r/olap.result: Added a test case for bug #48475. mysql-test/t/olap.test: Added a test case for bug #48475. sql/sql_select.cc: Disabled const-only table optimizations for the WITH ROLLUP case.
