请在下面查看我的存储过程。我试图从 CASE 语句中的参数传递值 1 或 0。

我得到的错误是在 SELECT 语句中调用 CASE 语句中的参数 @payment_status ：

消息 102，级别 15，状态 1，第 17 行 '=' 附近的语法不正确。

消息 102，级别 15，状态 1，第 21 行 '=' 附近的语法不正确。

这是脚本：

因为@payment_status 是一个“SELECT ...”，所以您需要用大括号将其包裹起来

h.payment_hold_flag = CASE 
  WHEN ('+@payment_status+') = 1 THEN ''On Hold''
  ELSE ''Not On Hold''
END as payment_hold_status

但是，除此之外，我会质疑语法：
, amount_open = (amt_net-amt_paid_to_date)
- 你的意思是
, (amt_net-amt_paid_to_date) as amount_open？
