Question

我有一个简单的查询，可以对数字进行平均，并按年和月分解。我遇到的问题是我无法按时间顺序找到按月计算结果的方法....以下是我的结果示例;

    Month       Year    AverageAmount
    ---------------------------------
    April       2012    167582.1139
    August      2012    206124.9323
    December    2012    192481.8604
    February    2012    227612.0485
    January     2012    214315.2187
    July        2012    195320.075
    June        2012    196174.3195
    March       2012    201199.9894
    May         2012    190526.0571
    November    2012    203441.5135
    October     2012    216467.7777
    September   2012    217635.9174
    April       2013    206730.5333
    August      2013    197296.0563

正如您在上表中看到的那样，月份按字母顺序排列......我需要的是按时间顺序排列的结果，即......

    Month       Year    AverageAmount
    ----------------------------------
    January     2012    214315.2187
    February    2012    227612.0485
    March       2012    201199.9894
    April       2012    167582.1139
    May         2012    190526.0571
    June        2012    196174.3195
    April       2012    206730.5333
    July        2012    195320.075
    August      2012    206124.9323
    September   2012    217635.9174
    October     2012    216467.7777
    November    2012    203441.5135
    December    2012    192481.8604
    January     2013    187268.3027
    February    2013    179755.0666
    March       2013    200131.6533

查询：

SELECT 
    datename(month, col1) Month,
    year(col2) Year,
    avg(col3) AverageAmount
FROM 
    myDB
GROUP BY 
    datename(month, datefunded), year(datefunded)
ORDER BY 
    year(datefunded), datename(month, datefunded)

非常感谢任何帮助

Answer 1

只需使用此ORDER BY：

ORDER BY 
    YEAR(datefunded), MONTH(datefunded)

这会按照datefunded

的年份和月份的数值对数据进行排序

Answer 2

看一下这个答案：Convert month name to month number in SQL Server

也许这解决了你的排序？您可以使用其中一个建议将月份转换为数字，例如三月＆gt;然后你按那个排序。
