从sql查询中删除一些记录

我从不同的表中编写了以下查询：

SELECT DISTINCT 0 AS IID, 
       pd.IID AS PurchaseOrerDetailsId, 
       i.[Description] AS ITEM, 
       '' AS BatchNo, 
       s.[Description] AS Unit,
       '' AS MfgDt, 
       0 AS QtyReceived, 
       '' AS ExpiryDate, 
       '' AS PackSize, 
       0 AS QtyOrdered, 
       0 AS MRP, 
       0 AS PTR,
       0 AS PTS, 
       0 AS PurchaseRate, 
       0 AS CGST, 
       0 AS SGST, 
       0 AS IGST, 
       0 AS DiscPer, 
       0 AS DiscVal, 
       0 AS PurchaseValue, 
       0 AS CGSTAmt,
       0 AS SGSTAmt, 
       i.IID AS ItemId
FROM   PurchaseOrderDetails pd
LEFT JOIN StockDetails sd ON pd.ItemId = sd.ItemId
INNER JOIN Items i ON i.IID = pd.ItemId
INNER JOIN Strings s ON s.IID = i.Unit
WHERE pd.PurchaseOrderId = 1

我得到以下结果：

现在我想消除前两条记录（PurchaseOrderDetailSID为1和2）。 任何线索

谢谢

您可以在CTE中使用行号（）作为[rn]，然后您可以选择[rn]>2。

我怀疑还有更多。但根据您提供的信息：

 and pd.IID > 2

您不使用

StockDetails sd

。左路连接是一种浪费

问题不需要所有这些硬编码的值。

将“WHERE pd.PurchaseOrderId=1”更改为“WHERE pd.PurchaseOrderId=1和PurchaseOrderDetailsID>2”在您的

WHERE

中添加一个

not IN

子句，也许吧？这看起来有点过分了
