Question

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。

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

Msg 102，Level 15，State 1，Line 17语法不正确＆＃39; =＆＃39;。

Msg 102，Level 15，State 1，Line 21语法不正确＆＃39; =＆＃39;。

这是脚本：

            @payment_status  VARCHAR(400)

    SET @End_Date = RIGHT('00' + CONVERT(VARCHAR(2), datepart(mm, @End_Date)), 2) + '/' + RIGHT('00' + CONVERT(VARCHAR(2), datepart(dd, @End_Date)), 2) + '/' + RIGHT('0000' + CONVERT(VARCHAR(4), datepart(yyyy, @End_Date)), 4)

Answer 1

因为@payment_status是'SELECT ...'，你需要用大括号包装它

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)
- 你的意思是什么？ , (amt_net-amt_paid_to_date) as amount_open？

CASE语句中的SQL参数
