我需要一个存储过程，它可以通过发送login 和password 来检查登录尝试时他们是否是有效用户如果它们在数据库中匹配.有没有简单的方法可以做到这一点?

I need a stored procedure that can check to see if, on a login attempt, whether or not they are a valid user by sending the login and password to see if they match in the database. Is there a simple way to do this?

推荐答案

如果没有更多信息，我目前能提供的最好的是:

Without more information the best I can offer for the moment is:

CREATE STORED PROCEDURE CheckPassword @username VARCHAR(20), @password varchar(20) AS BEGIN SET NOCOUNT ON IF EXISTS(SELECT * FROM usertable WHERE username = @username AND password = @password) SELECT 'true' AS UserExists ELSE SELECT 'false' AS UserExists END

根据您的回复修改查询 - 这将返回字符串true"或false"，如果您愿意，您可以分别用位值 1 和 0 替换它们.

Query amended based on your response - this will return the string 'true' or 'false' you could replace them with bit values 1 and 0 respectively if you prefer.
