- by Kamil Zadora
Hi I have following data in the table:
ID-----startDate----endDate

5567 2008-04-17 2008-04-30 1
5567 2008-05-01 2008-07-31 1
5567 2008-09-01 4712-12-31 2
5569 2008-05-01 2008-08-31
5569 2008-09-01 4712-12-31
5589 2008-04-18 2008-04-30
5589 2008-05-01 4712-12-31
5667 2008-05-01 4712-12-31
5828 2008-06-03 4712-12-31
5867 2008-06-03 4712-12-31
6167 2008-11-01 4712-12-31
6207 2008-07-01 4712-12-31
6228 2008-07-01 4712-12-31
6267 2008-07-14 4712-12-31
I am looking for I way to group the continuous time intervals for each id to return:
ID,
min(startDate),
max(endDate),
to have something like this in result for the bolded ID 5567
5567 2008-04-17 2008-07-31
5567 2008-09-01 4712-12-31
PL/SQL is also an option here :)
