Question

为什么我不能只删除sql server中的一行。

这是我的表和查询，请更正并给我解决方案。感谢...

ID                  IdSuratKeluar               Type   KodePosition
FDBC015F-8DCB-44F2-956F-262A3FB379B6    CE7A98B8-7A98-45FC-A338-322BD8BE02BD    2   0041
656CBFFA-F279-461D-B1B8-61D07B348223    CE7A98B8-7A98-45FC-A338-322BD8BE02BD    2   0037
656CBFFA-F279-461D-B1B8-61D07B348225    CE7A98B8-7A98-45FC-A338-322BD8BE02BD    2   0037

我对SqlServer的查询：

DELETE SuratKeluarPermission where KodeJabatan In 
( select Top(1) KodePosition from SuratKeluarPermission Where IdSuratKeluar='CE7A98B8-7A98-45FC-    A338-322BD8BE02BD' and KodePosition='0037')

Answer 1

这将从表中删除具有给定条件的随机行：

;WITH CTE as
( 
  SELECT Top(1) *
  FROM SuratKeluarPermission 
  WHERE 
    IdSuratKeluar='CE7A98B8-7A98-45FC-A338-322BD8BE02BD' and 
    KodePosition='0037'
  ORDER BY NEWID()
)
DELETE FROM CTE

免责声明：我无法看到哪个世界会有用

Answer 2

;WITH CTE AS
(
Select SuratKeluarPermission ,KodeJabatan,ROW_NUMBER()OVER(PARTITION BY KodePosition ORDER BY (SELECT NULL) ) RN from SuratKeluarPermission 
)
DELETE FROM CTE where RN > 1
