我将选择列表中的列添加到排序依据列表中，但它仍然给出错误:
如果指定了 SELECT DISTINCT，ORDER BY 项必须出现在选择列表中。
这是存储过程:
CREATE PROCEDURE [dbo].[GetRadioServiceCodesINGroup]
@RadioServiceGroup nvarchar(1000) = NULL
AS
BEGIN
SET NOCOUNT ON;
SELECT DISTINCT rsc.RadioServiceCodeId,
rsc.RadioServiceCode + ' - ' + rsc.RadioService as RadioService
FROM sbi_l_radioservicecodes rsc
INNER JOIN sbi_l_radioservicecodegroups rscg
ON rsc.radioservicecodeid = rscg.radioservicecodeid
WHERE rscg.radioservicegroupid IN
(select val from dbo.fnParseArray(@RadioServiceGroup,','))
OR @RadioServiceGroup IS NULL
ORDER BY rsc.RadioServiceCode,rsc.RadioServiceCodeId,rsc.RadioService
END
最佳答案
试试这个:
ORDER BY 1, 2
或者
ORDER BY rsc.RadioServiceCodeId, rsc.RadioServiceCode + ' - ' + rsc.RadioService
关于sql - 如果指定了 SELECT DISTINCT，则 ORDER BY 项必须出现在选择列表中，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/265628/
