SQL Server案例，其中包含多个条件

嗨，我遇到了第二个When条件的sql问题

当“1”时，则（'1000'、'1001'、'1003'、'1005'）
结束）

问题是：“，”附近的语法不正确。（102）

我的剧本：

SELECT MTRSUBSTITUTE.MTRL, MTRSUBSTITUTE.CODE AS EAN, MTRSUBSTITUTE.NAME AS WebName, MTRPACK.CODE AS SEAN, MTRSUBSTITUTE.MTRDIM1, MTRSUBSTITUTE.MTRDIM2, MTRL.CDIMCATEG1, MTRL.CDIMCATEG2, MTRL.WEBVIEW AS OnWeb, MTREXTRA.BOOL03 AS SkroutzFeed, MTRSUBSTITUTE.PRICER, MTREXTRA.BOOL01 AS Katastimata, SUM(ISNULL(CDIMFINDATA.OPNIMPQTY1,0)+ISNULL(CDIMFINDATA.IMPQTY1,0)-ISNULL(CDIMFINDATA.EXPQTY1,0)) AS Qty

  FROM CDIMFINDATA Inner JOIN MTRSUBSTITUTE ON CDIMFINDATA.MTRL=MTRSUBSTITUTE.MTRL AND CDIMFINDATA.CDIMLINES1=MTRSUBSTITUTE.MTRDIM1 AND CDIMFINDATA.CDIMLINES2=MTRSUBSTITUTE.MTRDIM2 INNER JOIN MTRL ON MTRSUBSTITUTE.MTRL=MTRL.MTRL

  INNER JOIN MTREXTRA ON MTREXTRA.MTRL=MTRSUBSTITUTE.MTRL

  LEFT OUTER JOIN MTRPACK ON MTRSUBSTITUTE.MTRPACK=MTRPACK.MTRPACK

  WHERE WEBVIEW=1 AND MTRSUBSTITUTE.ISACTIVE=1 AND MTRSUBSTITUTE.COMPANY=100 AND CDIMFINDATA.FISCPRD=2020 AND MTRL.SODTYPE=51   AND MTRL.MTRL=6139 AND  CDIMFINDATA.WHOUSE IN (CASE MTREXTRA.BOOL01 WHEN '0' THEN ('1001') WHEN '1' THEN ('1000', '1001', '1003', '1005') END)

  GROUP BY MTRSUBSTITUTE.MTRL, MTRSUBSTITUTE.CODE, MTRSUBSTITUTE.NAME, MTRPACK.CODE, MTRSUBSTITUTE.MTRDIM1, MTRSUBSTITUTE.MTRDIM2, MTRL.CDIMCATEG1, MTRL.CDIMCATEG2, MTRL.WEBVIEW, MTRSUBSTITUTE.PRICER, MTREXTRA.BOOL03, MTREXTRA.BOOL01, CDIMFINDATA.WHOUSE ORDER BY MTRSUBSTITUTE.CODE

Case表达式不能返回值列表，例如，您必须执行其他操作

AND  (
MTREXTRA.BOOL01 = '0' AND CDIMFINDATA.WHOUSE = '1001'
OR MTREXTRA.BOOL01 = '1' AND CDIMFINDATA.WHOUSE IN ('1000', '1001', '1003', '1005')
)
