我正在尝试在Windows应用程序中以大声的形式订购。我尝试使用以下代码:
using (SqlCommand sqlcomm = new SqlCommand("SELECT * FROM remaining WHERE username=@username and status=@status and company_status=@company_status ORDER BY call_case ASC , Payment_Status ASC", sqlconn))
这是正确的方法吗?
我要查找的是OrderBy(call_case)ASC,以及当call_case =(2-Answer)OrderBy(Payment_Status)ASC时。
( call_case ), ( Payment_Status )
null , null
1-No Answer , null
2-answer , 1-Promise Payment
2-answer , 2-Have Problem
2-answer , 3-Reject Payment
3- not Exist , null
请注意,以1-No Answer,2-answer,3- Not Exist这类数字开头的文本
答案 0 :(得分:1)
您可以将CASE
表达式与ORDER BY
一起使用
SELECT * FROM remaining
WHERE username=@username
and status=@status
and company_status=@company_status
ORDER BY
case when call_case='Answer' then 0 else 1 end ASC,
Payment_Status ASC
