SQL クエリを作成して実行する SP があります。最終結果は、一部のレポートに使用されます。ただし、このクエリの実行には長い時間がかかります ( 30 秒を超えると長時間になり、1 分以上かかることもあります)。
セットベースのクエリについて少し読んだことがありますが、この特定のクエリが適切かどうか、または変換する方法があるかどうかはわかりません。私がセットベースについて読んだことのほとんどは、セットベースの方法での SQL のプログラミングと T-SQL におけるセットベースと手続き型プログラミングのアプローチの紹介のような、ループをセットに変更することについて話しているようです。
クエリは次のようになります。
SELECT ProductionId, Max(ID) AS Id INTO #TEMP
FROM sdiProductionChemistry GROUP BY ProductionId

ID.InventBatchId AS CoilId, IT.DatePhysical AS DlvDate,IT.TransRefId AS SalesOrderId, 'RPS115898' As PackingSlipId,

それはちょっと長くて、それを作成する SP が長くなりますが、これをセットベースのクエリに変換できますか?
もしそうなら、どうやってこれを始めますか？
