Just to clarify what I meant. Functions in pl/sql only allow input arguments. You cannot write:

FUNCTION fred (arg1 OUT INTEGER) RETURN integer;

[download]

but you can write

FUNCTION fred (arg1 IN INTEGER) RETURN integer;

[download]

and the IN is implied anyway.

Also, I was not saying bind_param_inout would not work on an input only parameter but it is pointless using it and may require an unnecessary overhead on input only arguments.
