Subject:        Embedded SQL

I am using embedded SQL with a serial cursor using the declare, open,
fetch, close commands.  Is there a way to change the WHERE statement
<dynamically> in the rpg program?

For example, we have a report where the user can select a season or all
seasons.  If they choose a season then the WHERE clause includes the test
for a matching season.  If they choose all seasons there is no need for the
season test at all.
Here's an example:

Select one season:
   Declare c1 cursor for
     Select * from mstfil Where season = :season_in     and company =
:company_in
          Order by style

--or--  all seasons
   Declare c2 cursor for
     Select * from mstfil Where   company = :company_in



I tried using an IF statement but you have to repeat the entire select
statement and the cursor name must be different.  I'd like to keep the
cursor name the same and just change the WHERE clause on the fly.

Hope this is clearer than our company coffee.

Thanks!
