Description 

The following query defines a result set with a parameter:

SELECT id
FROM mytable
WHERE id < ?

The result set object defined in the C++ API that corresponds to this query has a parameter. You must set the value of the parameter before opening the generated result set object.

Parameters 

argnum    An identifier for the argument to be set. The first argument is 1, the second 2, and so on.

value-reference    A reference to the parameter value. The data type listing above provides the possibilities. As the parameter are passed as pointers, they must remain valid until used. Do not free them until they are used.

Returns 

true (1) if successful.

false (0) if unsuccessful. If you supply a parameter of the wrong data type, the method fails.
