这是我的表结构和示例行:
我有一个像这样的SQL查询:
WITH Test(ObjId, ObjectIcerik, KeyMi) AS
(
SELECT
ObjId, ObjectIcerik, KeyMi
FROM
Tek
WHERE
ObjId = 8
UNION ALL
SELECT
T.ObjId, T.ObjectIcerik, T.KeyMi
FROM
Tek T
INNER JOIN
Test as TE ON T.ObjParent = TE.ObjId
)
SELECT *
FROM Test
结果如下:
但如果父级KeyMi
列为“1”,我还需要隐藏父子行。
我需要在SQL查询中更改哪些内容才能执行此操作?

您应该只能将条件添加到递归CTE:
WITH Test(ObjId, ObjectIcerik, KeyMi) AS (
SELECT ObjId, ObjectIcerik, KeyMi FROM Tek
WHERE ObjId = 8 AND (KeyMI <> 1 OR KeyMI IS NULL)
UNION ALL
SELECT T.ObjId, T.ObjectIcerik, T.KeyMi
FROM Tek T INNER JOIN
Test TE
ON T.ObjParent = TE.ObjId
WHERE (t.KeyMI <> 1 OR t.KeyMI IS NULL)
)
SELECT *
FROM Test ;
