Alexander Barkov dc719597ee MDEV-18156 Assertion 0' failed or btr_validate_index(index, 0, false)' in row_upd_sec_index_entry or error code 126: Index is corrupted upon DELETE with PAD_CHAR_TO_FULL_LENGTH ... This change takes into account a column's GENERATED ALWAYS AS expression dependcy on sql_mode's PAD_CHAR_TO_FULL_LENGTH and NO_UNSIGNED_SUBTRACTION flags. Indexed virtual columns as well as persistent generated columns are now not allowed to have such dependencies to avoid inconsistent data or index files on sql_mode changes. So an error is now returned in cases like this: CREATE OR REPLACE TABLE t1 ( a CHAR(5), v VARCHAR(5) AS (a) PERSISTENT -- CHAR->VARCHAR or CHAR->TEXT = ERROR ); Functions RPAD() and RTRIM() can now remove dependency on PAD_CHAR_TO_FULL_LENGTH. So this can be used instead: CREATE OR REPLACE TABLE t1 ( a CHAR(5), v VARCHAR(5) AS (RTRIM(a)) PERSISTENT ); Note, unlike CHAR->VARCHAR and CHAR->TEXT this still works, not RPAD(a) is needed: CREATE OR REPLACE TABLE t1 ( a CHAR(5), v CHAR(5) AS (a) PERSISTENT -- CHAR->CHAR is OK ); More sql_mode flags may affect values of generated columns. They will be addressed separately. See comments in sql_mode.h for implementation details.		2019-09-03 05:34:53 +04:00
