- Type casting was not consequent, thus when adding a DATE type with a WEEK interval the result type was DATETIME and not DATE as is the norm. - By changing the order of the date internal enumerations the deviant type casting is resolved (Item_date_add_interval::fix_length_and_dec() which determines result type for this operation assumes that addition of any interval with value <= INTERVAL_DAY to date value will result in date). There are two independant places to change: interval_names[] and interval_type. mysql-test/r/func_date_add.result: Updated result file for type casting test mysql-test/r/func_time.result: Updated result file for type casting test mysql-test/t/func_date_add.test: Added test for type casting when adding intervals to date. sql/item_timefunc.cc: Changed order of "week" key word to match the date interval enumeration. sql/item_timefunc.h: Changed the order of the enumeration to better follow interval sizes.
