Question

下面工作正常，但我没有按月订单。你能告诉我什么想法吗？

SELECT SUM(TaxableAmt) [NSV], (UPPER(CONVERT(VARCHAR,LEFT(DATENAME(MM,invoicedate),3)))+'/'+ CONVERT(VARCHAR,RIGHT(DATENAME(YYYY,invoicedate),2))) AS MONTHYEAR  
FROM SALESDATA where (invoicedate >='4-1-2009' and invoicedate <='4-30-2010')
GROUP BY (UPPER(CONVERT(VARCHAR,LEFT(DATENAME(MM,invoicedate),3)))+'/'+ CONVERT(VARCHAR,RIGHT(DATENAME(YYYY,invoicedate),2)))

结果集是：

NSV                     MONTHYEAR  

45099947.4300001                  APR/09

您没有向SQL Server询问任何订单，可以按照自己喜欢的顺序自由返回数据。

这样做的一种方法（并将字符串操作减少到一个地方）：

select NSV,UPPER(SUBSTRING(DATENAME(month,MonYear),1,3)) + '/' + RIGHT(DATEPART(year,MonYear),2)
from
(SELECT SUM(TaxableAmt) [NSV],DATEADD(month,DATEDIFF(month,'20010101',invoicedate),'20010101') as MonYear
FROM SALESDATA where (invoicedate >='20090401' and invoicedate <='20100430')
GROUP BY DATEADD(month,DATEDIFF(month,'20010101',invoicedate),'20010101')
) t
ORDER BY MonYear

如何按月按顺序获取结果集中的数据？
