Hi all.
I have a table with some timestamps fields. For example this table:
* date1 | date2
-----------------------------+---------------------------
2004-03-01 11:20:00 | 2004-03-01 11:55:00*
If I do a query like this, I get:
/ SELECT date2 - date1 as diff FROM table/;
* diff
-------
00:35
(1 row)
*
but if I do a query like this, I get:
/ SELECT date2 - date1 as diff FROM table WHERE date2 - date1 >=
interval '15:00';/
* diff
------
(0 rows)
*
What can I do to do a query like the previous one , and get the right
answer??
Thanks !!
