c# - 如何在 SQL 中选择最早的日期？

Question

我有这个sql语句:

SELECT TOP (5) PartNumber,SerialNumber,MIN(WIP_CompletionDate) as dates
FROM dbo.FG_FILLIN where 
             Status='FG-FRESH'
             and WIP_Status<>'CMPL01' 
             and PartNumber='P02-070161-10211-C100'
            GROUP BY PartNumber,WIP_CompletionDate,SerialNumber

结果:

PartNumber                  SerialNumber               dates
P02-070161-10211-C100   21524100046CA8001806    2010-08-08 06:59:23.183
P02-070161-10211-C100   21524100046CA8001807    2010-08-07 16:26:19.477
P02-070161-10211-C100   21524100046CA8001808    2010-08-07 16:30:20.990
P02-070161-10211-C100   21524100046CA8001810    2010-08-14 13:12:58.827
P02-070161-10211-C100   21524100046CA8001811    2010-08-09 06:58:01.263

现在，如果我选择顶部 (2)，这就是我的结果。

P02-070161-10211-C100   21524100046CA8001806    2010-08-08 06:59:23.183
P02-070161-10211-C100   21524100046CA8001807    2010-08-07 16:26:19.477

但应该是我的结果会是这样的。

P02-070161-10211-C100 21524100046CA8001808  2010-08-07 16:26:19.477
P02-070161-10211-C100 21524100046CA8001808  2010-08-07 16:30:20.990

有什么建议吗？致谢

尝试将“ORDER BY WIP_CompletionDate ASC”添加到您的查询中，如下所示:

SELECT TOP (5) PartNumber,SerialNumber, WIP_CompletionDate 
FROM dbo.FG_FILLIN 
WHERE Status='FG-FRESH' AND WIP_Status<>'CMPL01' AND PartNumber='P02-070161-10211-C100' 
GROUP BY PartNumber, WIP_CompletionDate, SerialNumber 
ORDER BY WIP_CompletionDate ASC;
