事件是唯一的价值。

我正在寻找下面的输出。

Answer 1

Select a.typer, b.typer, a.EVENTID, a.TimeStampField, a.dateField from (
select * from table1 where typer like 'Audio%') a
left join
(select * from table1 where typer like 'Video%') b
on a.EVENTID = b.EVENTID
group by a.typer, b.typer, a.EVENTID, a.TimeStampField, a.dateField;

你走了。这是输出：

Type    Type    EVENTID TimeStampField  DateField
Audio1  Video1  1   11-JAN-15 12.33.49.000000000    11-JAN-15
Audio2  Video2  2   11-JAN-15 12.35.50.000000000    11-JAN-15
Audio3  Video3  3   11-JAN-15 12.33.49.000000000    11-JAN-15
Audio4  Video4  4   12-JAN-15 12.40.50.000000000    12-JAN-15
