Re: Embedded SQL

["John Taylor" <john.taylor@xxxxxxxxxxxxxxx>]

Tom,

How about using the BETWEEN clause? For example

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

When the user is selecting a season, set both host variables to the same
season. When they want all seasons, set season_low to *LOVAL, and season_hi
to *HIVAL.

Regards,
