MySQL变量错误

以下是不起作用的代码：

DECLARE @myTable TABLE (colName nvarchar(500), tableName nvarchar(500))

insert into @myTable

SELECT c.COLUMN_NAME AS colName, c.TABLE_NAME AS tableName, TABLE_SCHEMA tableSchema 
FROM information_schema.COLUMNS as c 
WHERE c.COLUMN_NAME like '%password%'

select * from @myTable

我的错误是：

[错误]脚本行：1-7-------------------------- 您的SQL语法有错误；检查与您的MySQL服务器版本对应的手册，以了解在“DECLARE@myTable TABLE”（colName-nvarchar（500），tableName-nvarchar（500））附近使用的正确语法

有人有什么想法吗？

你可以试试这个

  insert into myTable  

 SELECT c.COLUMN_NAME AS colName, c.TABLE_NAME AS tableName 
 FROM information_schema.COLUMNS as c 
 WHERE c.COLUMN_NAME like '%password%'

Mysql有点不同：

create table myTable (colName nvarchar(500), tableName nvarchar(500));

insert into myTable (colName, tableName)
    SELECT COLUMN_NAME, TABLE_NAME
    FROM information_schema.COLUMNS
    WHERE COLUMN_NAME like '%password%';

select * from myTable;

在使用SQL Server或MySQL时，请尽量避免使用@或写“@myTable”？在MySQL中不能使用“@”声明临时表。它应该是

创建临时表..

查看

create table myTable (colName nvarchar(500), tableName nvarchar(500));

insert into myTable (colName, tableName)
    SELECT COLUMN_NAME, TABLE_NAME
    FROM information_schema.COLUMNS
    WHERE COLUMN_NAME like '%password%';

select * from myTable;
