Hi all,
have such relation A:
PERIOD_ID | DATE_START | DATE_END | OTHER_ATTRIBUTES...
1 | 01.01.2010 | 01.02.2010 ....
2 | 03.02.2010 | 04.03.2010 .....
......
I want to search among periods for the set of periods which completely
covers passed search period.
As example - if I pass search period '15.01.2010 to 15.02.2010' the result
set must be empty because there is gap between 01.02 and 03.02.
please, suggest an idea how to implement this in SQL without writing a
procedure.
Thanks,
Anton
