Ramon - Start by adding an index? :-)
 
Do you have any indexes on this table? My first guess is that it is doing a
full table scan. This does seem to be a bit long for a full table scan. Do
you expect to do a lot of full table scans on this table? If so, then you
may want to look at how to tune the full table scan. Otherwise add an index.

Hi list,
 
I issue a select count(*) from mytable and last 30 seconds.
 
The table has 1,466,196 records and were loaded with a batch process, so
they are in a countinous space.
 
I consider that time exagerated.
 
The TBS is LMT with a Uniform size of 128 MB.
 
The block size is 8MB, version 9.2.0.1.0 in Windows 2000.
 
Where should I start looking ???
 
TIA
 
Ramon E. Estevez
