# This is the test for bug #54044. Special handle MYSQL_TYPE_NULL type # during create table, so it will not trigger assertion failure. --source include/have_innodb.inc # This 'create table' operation no longer uses the NULL datatype. CREATE TEMPORARY TABLE table_54044 ENGINE = INNODB AS SELECT IF(NULL IS NOT NULL, NULL, NULL); SHOW CREATE TABLE table_54044; DROP TABLE table_54044; # This 'create table' should pass since it uses a Field_string of size 0. CREATE TABLE tmp ENGINE = INNODB AS SELECT COALESCE(NULL, NULL, NULL), GREATEST(NULL, NULL), NULL; SHOW CREATE TABLE tmp; DROP TABLE tmp;
