dbo.Fn_GetRatio函数

Sorry, I am an AI language model and I am not aware of the specific function dbo.Fn_GetRatio. Can you provide more information or context about this function?

优化以下sql查询语句："select t_ICItemCore.FItemID,t_ICItemCore.fshortnumber,t_ICItemCore.fname,ICBOMChild.FScrap, PPBom.FBillNo,ICItemScrapEntry.FAuxQty,PPBomEntry.FAuxStockQty from dbo.t_ICItemCore INNER JOIN dbo.ICBOMChild ON dbo.t_ICItemCore.FItemID = dbo.ICBOMChild.FItemID INNER JOIN dbo.PPBom ON dbo.ICBOMChild.FItemID = dbo.PPBom.FItemID INNER JOIN dbo.ICItemScrapEntry ON dbo.PPBom.FItemID = dbo.ICItemScrapEntry.FItemID INNER JOIN dbo.PPBomEntry ON dbo.PPBom.FItemID = dbo.PPBomEntry.FItemID"

可以尝试以下优化措施：

1. 添加索引：对于t_ICItemCore表的FItemID列、ICBOMChild表的FItemID列、PPBom表的FItemID列、ICItemScrapEntry表的FItemID列和PPBomEntry表的FItemID列，分别添加索引可以提高查询速度。

2. 减少表连接次数：将PPBomEntry表和ICItemScrapEntry表的连接改为子查询，可以减少表连接次数。

优化后的SQL查询语句：

SELECT t_ICItemCore.FItemID, t_ICItemCore.fshortnumber, t_ICItemCore.fname, ICBOMChild.FScrap, PPBom.FBillNo, ICItemScrapEntry.FAuxQty, 
       (SELECT PPBomEntry.FAuxStockQty FROM dbo.PPBomEntry WHERE dbo.PPBomEntry.FItemID = dbo.PPBom.FItemID) AS FAuxStockQty
FROM dbo.t_ICItemCore 
INNER JOIN dbo.ICBOMChild ON dbo.t_ICItemCore.FItemID = dbo.ICBOMChild.FItemID 
INNER JOIN dbo.PPBom ON dbo.ICBOMChild.FItemID = dbo.PPBom.FItemID 
INNER JOIN dbo.ICItemScrapEntry ON dbo.PPBom.FItemID = dbo.ICItemScrapEntry.FItemID
