Hello TSM'ers



I'm doing some scripting that is using actlog queries fairly heavily, I
have noticed that

Select * from actlog where cast(date_time as date)=current_date and
process=1234

Is a lot slower than

Q actlog begint=-08:00 se=1234 (say, its 8am in the morning...)


Although you need to be carefull you are actually getting what you want
with the latter version.


Is TSM doing anything internally to generate a SQL statement that works
quicker than mine but gives the same/similar result? - I am assuming
that internally TSM takes q actlog (and other q commands) and generates
a SQL statement it then processes against the TSM DB, formatting the
result to generate the query output as non-tables.


Thanks,

Matt.
