results) Before this fix, the function BENCHMARK() would fail to evaluate expressions like "(select avg(a) from t1)" in debug builds (with an assert), or would report a time of zero in non debug builds. The root cause is that evaluation of DECIMAL_RESULT expressions was not supported in Item_func_benchmark::val_int(). This has been fixed by this change. mysql-test/r/func_misc.result: Added support for DECIMAL_RESULT in Item_func_benchmark::val_int() mysql-test/t/func_misc.test: Added support for DECIMAL_RESULT in Item_func_benchmark::val_int() sql/item_func.cc: Added support for DECIMAL_RESULT in Item_func_benchmark::val_int()
