Output 子句将结果连同源 ID 值插入到临时表中

Question

I have a table called TreeItemOption .

I need to insert new rows into TreeItemOption table from a temp table and save the mapped values in a different temp table

INSERT INTO ProductSetup.TreeItemOption (TreeItemHeaderId)
OUTPUT INSERTED.TreeItemOptionId, TI.TreeItemOptionId INTO #NewTreeItemOptionIds
    SELECT NTI.NewTreeItemHeaderId
    FROM #TTreeItem TI
    INNER JOIN #NewTreeItemHeaderIds NTI ON NTI.TreeItemHeaderId = TI.TreeItemHeaderId;

I have a #NewTreeItemHeaderIds table from that table I'm inserting the new TreeItemHeaderId into TreeItemOption table and I'm trying output the newly inserted TreeItemOptionId as well as old TreeItemOptionId from TTreeItem table

But I'm getting the error

The multi-part identifier "TI.TreeItemOptionId" could not be bound

In conventional insert and update commands,only Magic tables can only be used in the output clause. Try a merge statement instead if you want the value from your source table to also be mapped.

something like this

MERGE DestinationTable DEST
    USING SourceTable SRC
        ON DEST.ID = SRC.ID
    WHEN NOT MATCHED THEN
    INSERT
    (
        DestinationColumnName
    )
    VALUES
    (
        SRC.SourceColumnName
    )OUTPUT inserted.ID,SRC.SOurceID INTO #MyTemp;

One the above has been executed you'll have the records in the Temp table #MyTemp with the SourceID and the respective DestinationID mapped
