The getParam() method returns the value of an INOUT or OUT parameter identified by the number you specify in the fieldIndexparameter. getParam() returns the value as an object of the data type you specify in the fieldTypeparameter. Since getParam() returns the result as an instance of class Object, you must explicitly cast your inout_var variable to the correct data type.

If the OUT or INOUT parameter is of data type CHARACTER, then getParam returns a Java String Object. You must declare a procedure variable of type String, and explicitly cast the value returned by getParam to type String. Before calling getParam() you must call the SQLCursor.wasNULL method to test whether the returned value is NULL. If getParam() is called for a NULL value, it raises a DhSQLException.
