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
