How about this,

        get one of the Oracle gurus to create a coalesce function in the 
database that is functionally identical to the standard NVL function. It 
can then be used in any select statement.

John,

I tried this out as a workaround yesterday, but I get a run time error when 
my
program is executed. The error is ORA-00904: Invalid column name.
Is this because "coalesce" is not valid in Oracle?

Thanks
