MySQL中怎么修复临时表的TYPE=HEAP错误
TYPE=HEAP在较新的MySQL版本中已弃用。您可以使用ENGINE=HEAP代替TYPE。以下是语法-
ENGINE=HEAP;
让我们首先创建一个表。在这里，我们设置了Engine=HEAP-
create TEMPORARY table DemoTable -> ( -> StudentId int, -> StudentName varchar(30) -> )Engine = HEAP;
让我们检查表的定义-
show create table DemoTable;
输出结果
这将产生以下输出-
+--------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | 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)
