DerbyParameterNamesDAO (IBM FHIR Server)

java.lang.Object
- com.ibm.fhir.persistence.jdbc.dao.impl.ParameterNameDAOImpl
- - com.ibm.fhir.persistence.jdbc.derby.DerbyParameterNamesDAO

All Implemented Interfaces:

ParameterNameDAO
```
public class DerbyParameterNamesDAO
extends ParameterNameDAOImpl
```
For R4 we have replaced the old Derby (Java) stored procedure with plain old JDBC statements - much simpler and easier to debug.
