SQL部分

ALTER PROCEDURE [dbo].[sp_ChangePassword]
(
 @CustID  VARCHAR(10),
 @OldPassword VARCHAR(10),
 @NewPassword VARCHAR(10)
 
)
AS
IF EXISTS(SELECT * FROM dbo.A_User WHERE CustID=@CustID and [Password]=@OldPassword)
BEGIN
 UPDATE dbo.A_user SET [Password]=@NewPassword WHERE CustID=@CustID
 SELECT result=1 ---得到表
END
ELSE
BEGIN
 SELECT result=0 --得到表
END

-----后台部分

/// <summary>
 /// 改变密码
 /// </summary>
 /// <param name="CustID">编号</param>
 /// <param name="oldPassword">旧密码</param>
 /// <param name="newPassword">新密码</param>
 /// <param name="StoredProcedureName">存储过程名称</param>
 /// <returns></returns>
 public static int sp_getOldPwd_and_updatePwd(string CustID,string oldPassword,string newPassword, string StoredProcedureName)
 {

 try
 {
 //传入参数
 SqlParameter[] para = new SqlParameter[3];
 para[0] = new SqlParameter("@CustID", typeof(string));
 para[0].Value = CustID;
 para[1] = new SqlParameter("@OldPassword", typeof(string));
 para[1].Value = oldPassword;
 para[2] = new SqlParameter("@newPassword", typeof(string));
 para[2].Value = newPassword;
 return Convert.ToInt32(SqlHelper.ExecuteScalar(strConn,CommandType.StoredProcedure,"sp_ChangePassword",para));
 ----ExecuteScalar 返回得到第一行第一列 也就是  SELECT result=1 或  SELECT result=0
 }
 catch (Exception ex)
 {
 throw ex;
 }
 }
