Question

select date_add('2015-01-15',(7-dayofweek('2015-01-15')),"day"),
        date_add('2015-01-15',(14-dayofweek('2015-01-15')),"day")

此查询的输出是

Row f0_ f1_  
1   2015-01-17 00:00:00 UTC 2015-01-24 00:00:00 UTC

但我希望将数据显示为

sno    date                      sum
1  2015-01-01 00:00:00 UTC        20(first month sum)
2 2015-02-01 00:00:00 UTC         30 (second month sum)

Answer 1

STRFTIME_UTC_USEC具有丰富的日期格式，月份名称的代码为％b，即

select strftime_utc_usec(date_add('2015-01-15',
          (7-dayofweek('2015-01-15')),"day"), "%Y-%b-%e"),
       strftime_utc_usec(date_add('2015-01-15',
          (14-dayofweek('2015-01-15')),"day"), "%Y-%b-%e")

结果

Row f0_         f1_  
1   2015-Jan-17 2015-Jan-24

作为附录，如果要以多行显示每个月的数据，可以使用GROUP BY。这里有一个例子：Using a timestamp function in a GROUP BY。
