DB2数据库计算日期,统计系统时间(月)的数据
计算出本月第一天到最后一天的日期:--selectdate(rtrim(char(year(min(start_time))))||'-'||rtrim(char(month(min(start_time))))||'-1') as startTime,date(rtrim(char(year(max(start_time))))||'-'||rtrim(char(month(max(start_time)+1 month)))||'-1') as endTime from table_A t;
这个语句有点问题,月份是12月的时候,计算的年,没变化。
计算出本月时间和下月时间的日期:
selectdate(start_time) as startTime,date(start_time) +1 month as endTime from REPAYMENT
统计本月数据:
select sum(MONTHLY_REPAYMENTS) as totle from TABLE_A where ID='123'
ANDdate('2012-11-01') <date(current timestamp)anddate('2012-12-01') > date(current timestamp)
