我正在尝试从多个表中获取数据并将它们导入到其他表中。目标使用标识ID和源表具有不同的标识。我需要从插入中获取新的身份标识，并将它们添加到目标数据库中的另一个表。这是我到目前为止，但不知道如何让它工作。我尝试将TMMYId添加到OUTPUT，但这不起作用。

SELECT MakeID, ModelID, YearID, T.id TypeMakeModelYear T
JOIN Fitment F
ON F.TMMYID = T.id JOIN PartToAppCombo P ON F.PartToAppComboID = P.ID
WHERE P.PartmasterID IN (SELECT PP.PartMasterID FROM PartPriceInv PP WHERE Discontinued
= 0)
DECLARE @MakeOutput TABLE (MakeId int, TMMYId int)
