试试这个：

CREATE PROC [dbo].[bb_UpdateContactId] 
@ContId int, @UserId int
AS 
SET NOCOUNT ON 
SET XACT_ABORT ON  

BEGIN TRAN  

if exists
(select * 
 from [bb_Contact] 
 where [ConId]= @ContId 
       and @UserId = [User_Id])
    update [bb_Contact]
    set [UserStatus]=1
    where [ConId]= @ContId
    and @UserId = [User_Id]
else
    update [bb_Contact]
    set [ContUser_Id]=1
    where [ConId]= @ContId
    and @UserId=[ContUser_Id]

COMMIT

使用case或if else条件存储过程以获取更新记录
