Nulls allowed
For native ORACLE support, the Nulls allowed setting has special use. When this setting it checked, the field is assumed to be used for output only. Before calling the stored procedure, fields with the Nulls allowed setting are set to nil. This setting is helpful when you want to flush the output buffer. If you do not set Nulls allowed, then you are responsible for clearing necessary field buffers before calling the procedure.
