从mysql数据库读取一行并将字段保存到用户定义的变量 [英] Reading a row from mysql database and saving fields to user defined variables

问题描述

嗨
我想知道是否有人对实现以下目标有任何想法:

说我要执行以下操作:

从用户所在位置选择用户名，用户名，用户电话，用户名

现在说我想将上面返回的字段存储到用户定义的变量中.
例如:

SET @Name:= User.Name
SET @Phone:= User.Phone

我该怎么做?

以及如何在mysql中执行if语句.
示例:

如果@Name = John然后插入ADMINTABLE()VALUES()
否则，如果@Name = Paul，然后插入SUPERISOR()VALUES()

我如何实现上述目标?

有没有一种方法可以遍历返回的每一行并针对结果运行函数?

请有人帮忙解决上述任何问题

在此先感谢

Hi
I would like to know if anyone has any idea on how to achieve the following:

Say i do the following:

SELECT User.Name, User.Surname, User.phone FROM User WHERE User.ID = 1

Now say i want to store the fields returned above to user defined variables.
example:

SET @Name := User.Name
SET @Phone := User.Phone

How do i do this??

And how to i do an if statement in mysql.
Example:

If @Name = John THEN INSERT INTO ADMINTABLE() VALUES()
ELSE IF @Name = Paul THEN INSERT INTO SUPERISOR() VALUES()

How do i achieve the above?

And is there a way to iterate thru each row returned and the run functions against results?

Please someone help with any of the above

Thanks in advance

嗨艾希(Ashy)

我认为您可以在select语句中设置一个变量，如下所示:

Hi Ashy

I think you can set a variable inside select statement like this:

SELECT

@Name := User.Name, @Phone := User.phone FROM User WHERE User.ID = 1

检查此 http://dev.mysql.com/doc/refman/5.0/zh-CN /user-variables.html [ ^ ]

要熟悉mysql if else语句，请阅读:
