Sql单列不同数据统计问题
[id] [AgtentId] [Money] [Type] [Date]

1 1 10.00 1 2012-12-27

2 2 10.00 2 2012-12-27

3 1 10.00 1 2012-12-20

4 1 10.00 1 2012-12-20

id是主键

出来的结果希望：

以 AgtentId 和 Date 分组，统计出每个 AgtentId 的当天 Money 总和按 Type 统计显示不同的名称。

[AgtentId] [类型1] [类型2] [Date]

1 10.00 0 2012-12-27

2 0 10.00 2012-12-27

1 20.00 0 2012-12-20





[解决办法]

SELECT AgtentId,[type 1]=SUM(CASE WHEN type = 1 THEN money ELSE 0 END),
[type 2]=SUM(CASE WHEN type = 2 THEN money ELSE 0 END) ,
date 
FROM dbo.TB
GROUP BY AgtentId,date
ORDER BY date
