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 |
