    public class SqlInOutParameter

extends SqlOutParameter

Subclass of `SqlOutParameter` to represent an INOUT parameter. Will return `true` for SqlParameter's `isInputValueProvided()` test, in contrast to a standard SqlOutParameter.

Output parameters - like all stored procedure parameters - must have names.
