oracle触发器获取给定日期之间的所有日期

Question

表：given_dates

BOOK_DT1  BOOK_DT2  USERID    
--------- --------- --------------------
22-SEP-17 12-NOV-17 rahul    
20-JAN-17 10-FEB-17 ABC    
02-MAR-17 10-MAR-17 ZXC    
13-NOV-17 14-NOV-17 tth

当我插入一行时：

insert into given_dates('01-JAN-2017','05-JAN-2017','AAA');

应调用触发器将细节插入另一个表中，如下所示

table：all_dates_used

表：given_dates

DATET1     USERID    
---------  ---------
01-JAN-17     AAA    
02-JAN-17     AAA    
03-JAN-17     AAA    
04-JAN-17     AAA    
05-JAN-17     AAA

Answer 1

如果我理解你的需要，这可能是一种方式：

        int[] ints = new[] { 1, 2, 3, 4, 5, 6, 7, 8, 9 };
        ints = ints.Select((x, index) => new { Value = x, Index = index })
               .OrderBy(tuple => (tuple.Index >= start && tuple.Index <= stop) ? random.Next(start, stop) : tuple.Index)
               .Select(tuple => tuple.Value)
               .ToArray();

<强>测试

create or replace trigger insertDates
after insert on given_dates
for each row
begin
    insert into all_dates_used(DATET1 , USERID)
    select :new.BOOK_DT1 + level -1, :new.USERID
    from dual
    connect by :new.BOOK_DT1 + level -1 <= :new.BOOK_DT2;
end;
