Oracle批量插入有日期类型数据

Posted 2020-10-02 deluo

例如现在有张表

id(number)	startTime(date)	name(varchar2)
1	2017-08-13	zhangsan
2	2017-08-14	zhangsan

需要批量插入name为zhangsan，日期以天递增，一个月的数据

1 insert into t(id,date,name) 
2 select level,trunc(current_timestamp)+level,‘zhangsan‘
3     from dual
4 connect by level<= add_months(trunc(current_timestamp),1)-trunc(current_timestamp)

add_months(time,months)

　　Oracle的自带的日期函数，在time这个时间上增加或减少months个月

select add_months(current_timestamp,6) from dual
--在当前时间加上半年
select add_months(current_timestamp,-1) from dual
--在当前时间减去一个月
