Fix Error with TYPE=HEAP for temporary tables in MySQL?
The TYPE=HEAP deprecated in newer MySQL versions. You can use ENGINE=HEAP instead of TYPE. Following is the syntax −
ENGINE=HEAP;
Let us first create a table. Here, we have set Engine=HEAP −
mysql> create TEMPORARY table DemoTable -> ( -> StudentId int, -> StudentName varchar(30) -> )Engine = HEAP; Query OK, 0 rows affected (0.00 sec)
Let us check the definition of table −
mysql> show create table DemoTable;
Output
This will produce the following output −
+--------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Table | Create Table | +--------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | DemoTable | CREATE TEMPORARY TABLE `DemoTable` (`StudentId` int(11) DEFAULT NULL,`StudentName` varchar(30) COLLATE utf8_unicode_ci DEFAULT NULL) ENGINE=MEMORY DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci | +--------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ 1 row in set (0.00 sec)
