2个字段比较~
OutStockDetailID GoodsID
1 200703010001
1 200703010001
1 200703010001
2 200703010005
2 200703010005
3 200703010007
3 200703010008
这一个表里的2个字段 如果OutStockDetailID和GoodsID的内容一摸一样就不显示,如果不一样(OutStockDetailID为3的对着GoodsID有2种)就显示出来 要怎么写?
------解决方案--------------------select OutStockDetailID,GoodsID from t1 group by OutStockDetailID GoodsID having count(1)> 1;
------解决方案--------------------Select Table_1.OutStockDetailID,Table_1.GoodsID
From Table_1 join (Select OutStockDetailID,Stdev(cast(GoodsID as int)) Count
From Table_1 Group By OutStockDetailID) temp on Table_1.OutStockDetailID=temp.OutStockDetailID and temp.Count> 0
