[ADSM-L] Select on / dum/export of backups table
2008-03-04 14:56:55
Hi,
I would like to do some queries on the backups table. I tried to run me
first query however that takes really long and so far I didn't get a
result yet. I Iread that queries on the backups table aren't really
speedy or even possible.
So how can I dump or export the whole table to a file? I cannot (do not
want to) use dsmc on the nodes as I would like to run the queries on
serveral nodes on several platforms.
Is there a way to enhance sql queries despite from using indexed fields
(node_name in this case)?
Let's say the query is like that (maybe this doesn't make sense it's
just an example): select * from backups where node_name in (select
distinct node_name from filespaces where filespace_name like
'%ORACLE%') and class_name like 'MCLASS%'
Is the performance better if the select in the where clause has the
last position?
Regards,
..--Egonle
