RE: Date functions in SQL/400

["Pytel, Alexei" <pytela1@xxxxxxxxxxxxxxxx>]

There's a date format parameter, associated with ISQL session or CRTSQL*
commands.
This format should correspond with date format in the database field,
otherwise SQL will not interpret date properly.


    Best regards,

          Alexei Pytel
