【急求】求教SQL语句时间查询问题
- SQL code
SELECT SUM(TotalPrice) FROM NarukoEC.dbo.Orders AS oWHERE CreateTime BETWEEN '20110101' AND '20110131' AND o.TotalGoodsPrice>0 AND NOT EXISTS(SELECT 1 FROM NarukoEC.dbo.Orders WHERE state not in(0,5,7) AND CreateTime < '20110101' AND CustomerID = o.CustomerID)
- SQL code
SELECT SUM(TotalPrice) FROM NarukoEC.dbo.Orders AS oWHERE CreateTime BETWEEN '20110201' AND '20110228' AND o.TotalGoodsPrice>0 AND NOT EXISTS(SELECT 1 FROM NarukoEC.dbo.Orders WHERE state not in(0,5,7) AND CreateTime < '20110201' AND CustomerID = o.CustomerID)
我要依次查询 二零零一年一月份 到 十二月份每个月的数据，这样写的话就每次都要改动月份！
如何让它一次性就全部查询出来？

- SQL code
SELECT SUBSTRING(CreateTime,5,2),SUM(TotalPrice)FROM NarukoEC.dbo.Orders AS oWHERE o.TotalGoodsPrice > 0 AND [state] IN ( 0, 5, 7 )GROUP BY SUBSTRING(CreateTime,5,2)
