sql - 在sql中获取月度报告

Question

我得到了我的数据库列日志，数据，类型如何从现在开始获取日志，并区分月份 f.ex：行

logs = 'error...'
data = 2012-11-05 11:24:08
type = 1

....我想让他们在那个视图中

month     logs-count   type
January     100         1
January     100         2
February    160         1
February    120         2
 ....

Answer 1

试试这个，如果这些列在同一个表中

select monthname(data) as month,count(logs)as logs-count,type from table
 group by month

Answer 2

对于 mysql：

select monthname(data) as month, count(*) as logs-count, type
  from table
  group by month, type

您需要按日期和类型分组才能每月获得多行。

Answer 3

试试这个：

select datename(month, data) as month count(logs)as logscount, type from table
