| | * | MDEV-13358: FIRST_V throw SQL Fehler (1292): Incorrect datetime value | Vicențiu Ciorbaru | 2017-09-19 | 1 | -9/+7 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is backport of 25ad623d64e for 10.2. The issue is similar to the one from MDEV-13240. Item::save_in_field() returns an error during tmp table population in a create table from select query as we try to save an empty string as a date value when force_return_blank is set to true for window functions. MDEV-13240 Wrong warning with MAX(datetime_field) OVER (...) The problem resided in Item_window_func implementation, and it was revealed by bb-10.2-ext specific changes: Item_window_func::save_in_field() works differently in bb-10.2-ext vs 10.2: - 10.2 goes through val_str() - bb-10.2-ext goes through get_date(), due to Type_handler related changes. get_date() tries to convert empty string to DATETIME, hence the warning. During a discussion with Vicentiu, it was decided to fix Item_window_func::val_xxx() to return NULL (instead of an "empty" value, such as 0 for numbers and '' for strings) when force_return_blank is set. | ||||
| | * | MDEV-12851: Case with window functions query crashes server | Vicențiu Ciorbaru | 2017-06-28 | 1 | -0/+11 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "is null" function performs one operation which no other Item_func does, which is to update used tables during fix_length_and_dec(). This however can not be performed before window functions have had a chance to resolve their order by and partition by definitions, which happens after the initial setup_fields call. Consequently, do not call Item_func_isnull update_used_tables during fix_length_and_dec(). There was another issue detected once the crash was resolved. Because window functions did not implement is_null() method, we would end up returning bad results for "is null" and "is not null" functions. Implemented is_null() method for Item_windowfunc. | ||||
