我正在尝试创建一个查询,它将显示这样的销售额:
Jan Feb Mar ...
2011 1253 1381 1973 ...
2012 3124 3829 1823 ...
顶部显示从 1 月到 12 月的月份,左侧列显示年份。该数据是该年/月整个期间的 SUM 数据。
该表包含总计和日期时间字段的销售记录。
我已经看到了一些使用 UNPIVOT 的选项,但我无法理解它。
谢谢
在没有看到您的表结构的情况下,您可以执行类似的操作
select
year( YT.YourDateColumn ) as SalesYear,
sum( if( month( yt.YourDateColumn ) = 1, YT.SalesAmt, 000000.00 )) as Jan,
sum( if( month( yt.YourDateColumn ) = 2, YT.SalesAmt, 000000.00 )) as Feb,
sum( if( month( yt.YourDateColumn ) = 3, YT.SalesAmt, 000000.00 )) as Mar,
sum( if( month( yt.YourDateColumn ) = 4, YT.SalesAmt, 000000.00 )) as Apr,
sum( if( month( yt.YourDateColumn ) = 5, YT.SalesAmt, 000000.00 )) as May,
