sql server/sql使用select查询总结

0
265

一、常用语句

select * from table

二、常用条件/字段

1.在语句最后面加上 这一句,即可隐藏结果为0的行

 having sum( SEOutStockEntry .FQty- SEOutStockEntry .FAuxStockQty) != 0  

2.通过主键联查对应单据

–联查出 即时库存数量
select FQty,FItemID from ICInventory where ICInventory.fqty !=0 and ICInventory.FItemID =(select FItemID from t_ICItem where t_ICItem.FName=’MT6261DA’ )

三、多表联查

—待出库数量(取自发货通知单上) –FClosed=0 是单据未关闭 (发货通知单上的单据数量-出库数量= 待出库数量) 单据保存就增减库存。。。。(加上t_Stock.FName is not null 隐藏仓库为null的值)

  select  t_Stock.FName as 仓库名称,t_ICItem.FName as 物料名称 ,t_ICItem.FModel as 规格型号,sum(SEOutStockEntry.FQty-SEOutStockEntry.FAuxStockQty)  as  待出库数量
  from SEOutStock
 left join  SEOutStockEntry  on  SEOutStock.FInterID=SEOutStockEntry.FInterID
 left join t_Stock on t_stock.FItemID=SEOutStockEntry.FStockID
 left join t_ICItem on t_ICItem.FItemID=SEOutStockEntry.FItemID
 where  SEOutStock.FClosed='0'     and  t_Stock.FName is not null  
 GROUP BY t_Stock.FName ,t_ICItem.FModel,t_ICItem.FName
 having sum( SEOutStockEntry .FQty- SEOutStockEntry .FAuxStockQty) != 0
