```
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.
