Re: My last comments... I may be thinking about group by's, not order
by's...
I'm confusing myself... :-)

Anyone have any problems with the CBO not using
a index when you know it is faster by forcing a
hint ?

I have set the following ...

Solaris
Oracle Version 8.1.7.4

block size = 8
DB_FILE_MULTIBLOCK_READ_COUNT = 8
mode = Choose

also using Tim Gormans 90 and 50 values for the other optimizer parms.

Select col1, col2, col3, blah1, blah2 from table order by col1, col2, col3;


Concatenate index on col1, col2, col3.
