Hello!
I have a table that, among other columns, has two datetime columns which indicate the initial and the final time. This would be an exemple of data in this table:
row1:
initial_time: 2006-05-24 8:00:00
final_time: 2006-05-24 8:30:00
row2:
initial_time: 2006-05-24 8:35:00
final_time: 2006-05-24 9:15:00
I would like to split a row in two new rows if final time's hour is different of initial time's hour, so I would like to split row2 into:
row2_a:
initial_time: 2006-05-24 8:35:00
initial_time: 2006-05-24 8:59:59
row2_b:
initial_time: 2006-05-24 9:00:00
initial_time: 2006-05-24 9:15:00
Is it possible to do it in a query, I mean, without using procedures?
Thank you!
? It gets a bit complex, but here's one way: create table #table ( initial_time datetime, final_time datetime) insert #table values( '2006-05-24 8:00:00', '2006-05-24 8:30:00') insert #table values( '2006-05-24 8:35:00', '2006-05-24 9:15:00') SELECT CASE x.N WHEN 0 THEN T.initial_time WHEN 1 THEN DATEADD(ms, ((DATEPART(minute, T.final_time) * 60000) + (DATEPART(second, T.final_time) * 1000) + DATEPART(millisecond, T.final_time)) * -1, T.final_time) END AS initial_time, CASE x.N WHEN 0 THEN CASE DATEDIFF(hour, T.initial_time, T.final_time) WHEN 0 THEN T.final_time WHEN 1 THEN DATEADD(millisecond, -3, DATEADD(millisecond, ((DATEPART(minute, T.final_time) * 60000) + (DATEPART(second, T.final_time) * 1000) + DATEPART(millisecond, T.final_time)) * -1, T.final_time)) END WHEN 1 THEN T.final_time END AS final_timeFROM #table TJOIN( SELECT 0 UNION ALL SELECT 1) x (N) ON x.N <= DATEDIFF(hour, T.initial_time, T.final_time) drop table #tablego -- Adam MachanicPro SQL Server 2005, available nowhttp://www..apress.com/book/bookDisplay.html?bID=457-- <AnaC@.discussions.microsoft..com> wrote in message news:bdb330d8-5a34-409c-aaf3-57044628fc13@.discussions.microsoft.com...
