This article will explain in detail how to implement stored procedures in C#. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

C # stored procedure source code

Public static int VerifyUser (clsUser user)

{

Int iRet

String sql = String.Format ("EXECUTE VerifyUser @ myVerifyReader OUTPUT"

'{0}','{1}'", user.username,user.password)

/ / T-SQL string executed

SqlCommand scmd = new SqlCommand (sql, conn)

Scmd.Parameters.Add (new SqlParameter ("@ myVerifyReader", SqlDbType.Int))

Scmd.Parameters ["@ myVerifyReader"] .Direction = ParameterDirection.Output

/ /

DBOpen (conn)

/ / there is a problem with the return value

Scmd.ExecuteNonQuery ()

IRet = (int) scmd.Parameters ["@ myVerifyReader"] .Value

DBClose (conn)

Return iRet

}

SQL SERVER stored procedure

CREATE PROCEDURE VerifyUser

(

@ myVerifyReader int OUTPUT,-- returns the result

@ username varchar (50)-- user name

@ userpassword varchar (50)-user password

)

AS

IF EXISTS (SELECT [id] FROM [Users] WHERE username =

@ username AND userpassword = @ userpassword)

SET @ myVerifyReader = 0-- verified

ELSE IF EXISTS (SELECT [id] FROM [Users] WHERE username = @ username)

SET @ myVerifyReader = 1-user exists and the password is incorrect

ELSE

SET @ myVerifyReader = 2-- user does not exist

RETURN isnull (@ myVerifyReader,3)
