I am reading Jonathon Lewis' book - Practical Oracle8i. The problem is we
need to return dynamic (based on values but not data elements) queries from
Crystal Reports to Oracle backend. The develper would like to use stored
procs. as in SQL Server apparently they can easily run SQL within a stored
proc for returning large datasets. In Oracle it appears that you have to
identify a cursor (like refcursor) or global temporary table or object????.
The user has tried with refcursors but there is performance degradation. It
appears it could be the way that Oracle CBO works with PL/SQL versus native
SQL. The 3rd party tool in this case is Crystal Reports. Some ideas are
use Oracle Reports (learning curve, setup?), use a macro in another language
VB or C to pass native SQL, nest Crystal Reports? How do we get the best
performance with the least amount of maintenance when we have a standard set
of queries where data elements don't change but the values do and am using a
3rd party tool for reporting on the web!!!!
