I have posted this issue before with little response and really need
a solution as any help would be much appreciated.

I have been using the firebird api (firebird 1.50 CS) to pass
input parameters to some statements. When I try and pass NULL as a
input parameter I get an SQL error (-804 - An
error was found in application input parameters for the SQL
statement!!) error on Linux.

Has anybody come across the same problem?

Is there a work around?


Does anybody have example code of passing NULL as an input parameter
that works on Linux ?

Thanks in advance.
I am probably missing the obvious solution as I cannot believe
someone has not tried to do this before.
