Question

嘿，我似乎无法解决这个问题，我有这个问题：

SELECT  DISTINCT CONVERT(VARCHAR(8), time, 4) AS Batch  
FROM Calls 
ORDER BY Batch

按天计算列数而不是常规日期，这意味着我得到的结果如下：

1.11.12
1.12.12
2.11.12
3.11.12
4.11.12

我怎么能解决这个问题？如果我按时间尝试按顺序排序，查询将不会区分值并扰乱我的所有查询。

这意味着：

SELECT  DISTINCT CONVERT(VARCHAR(8), time, 4) AS Batch , time 
FROM Calls 
ORDER BY time, Batch

将查询排序正常但不会区分值。

Answer 1

试试这个

SELECT  DISTINCT CONVERT(VARCHAR(8), time, 4) AS Batch
FROM Calls 
ORDER BY time, Batch

<强>更新

select convert(varchar(8), time, 4) as [Batch]
from [Calls]
group by convert(varchar(8), time, 4)
order by convert(datetime, convert(varchar(8), time, 4), 4)
