使用output＆into子句将数据插入两个表

Question

i would like to move some staging data to production table and delete staging data and inserting history data for production table at the same time if it is possible. i want to do something like below:

DELETE FROM _stagingTable
OUTPUT deleted.idTest, deleted.textTest
INTO _productionTable(idTest,textTest)
--Below is what im not sure
OUTPUT 'Add',deleted.idTest, deleted.textTest
INTO _productionTableHistory(typeTest, idTest, textTest)

Is it possible to use output clause more than once? Or what do you suggest me to do?

Thanks in advance

Answer 1

The answer is no you cannot directly do what you want.

If you do not want to use a trigger solution and you do not want a query based on a primary key then I think you want a temp table.

Output into #TempHoldTable, then insert into table1 from #TempHoldTable and insert into table2 from #TempHoldTable.

Answer 2

I think this is the idea:

DELETE FROM _stagingTable
    OUTPUT deleted.idTest, deleted.textTest
    INTO _productionTable(idTest, textTest);

INSERT INTO _productionTableHistory(typeTest, idTest, textTest)
    SELECT 'Add', idTest, textTest
    FROM _productionTable pt;

These are two separate statements. You can wrap them into a single transaction, if you need to.

If you are concerned about data in _productionTable , then truncate it before using it in the output clause. Given that it starts with an underscore, I find it hard to believe that the intention is not a temporary place just for this statement, but I don't know the naming conventions being used.
