ALTER PROCEDURE [dbo].[Signin_Check] 
    @uid varchar(50), @pwd varchar(50), @uname varchar(50) output
AS
   IF EXISTS (SELECT * FROM threeLayer_user WHERE uid = @uid and pass = @pwd)
   BEGIN
      -- SET NOCOUNT ON added to prevent extra result sets from
      -- interfering with SELECT statements.
      SET NOCOUNT ON;

      SELECT @uname = name 
      FROM threeLayer_user 
      WHERE uid = @uid and pass = @pwd

      RETURN @uname
   END
