# 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;
