Re: SQL problem ....

Hi Kolbeinn,

This was it ! Now you gave me the solution, I believe I really should
have drank some more coffee ;-)
Many thanks, cheers.
Arnaud

try this:

stgpool_name='COPYLTO1_WIN') from occupancy where stgpool_name
='TAPELTO1_WIN'

Hi list,

Could any SQL genius explain me wat is wrong with this statement :

select sum(physical_mb) from occupancy where stgpool_name='TAPELTO1_WIN'
- (select sum(physical_mb) from occupancy where
stgpool_name='COPYLTO1_WIN' )

When trying to use it II get following output :
ANR2916E The SQL data types CHAR(12) and DECIMAL(31,2) are incompatible
for operator '-'. I already tried to add "dec()" on both selects without
achieving any valuable result ... is it a bug or do I need  additional
coffee to wake up my mind ? What I'm trying to achieve is to calculate
the remaining amount of data to copy before a backup stgpool process
finishes. Thanks in advance ! Cheers.

Arnaud
