Hi,

I have two columns of type TIMESTAMP defined inside a table:
start_date and stop_date. Is there any way I can calculate
how many days between start_date and stop_date inside my SELECT
clause so that I do not have do it after I get these two values
from my database?

regards,

Rick,
In db2, there is a days() function. So you could easily subtract in your select clause. I don't remember if this is db2 specific though.

Also in MSSQL you can use DATEDIFF function.

In Oracle, AFAIK, you can just subtract one date from the other to get the number of days
