mysql要怎么循环
之前一直在弄MSSQL
mysql要怎么循环，一个循环弄了好久，网上都找不到什么资料。
SET @a=1;
WHILE @a<10
DO
SET @a=@a+1
END WHILE;
SELECT @a;
会报错
#1064 – You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘WHILE @a<10
DO
SET @a=@a+1
END WHILE’ at line 1
delimiter $$
CREATE PROCEDURE ptest()
BEGIN
SELECT ‘Hello Word!’;
END$$
delimiter ;
直接在MYSQL命令行工具中先测试一下。
