public boolean isReturnResultSetSupported()
```
    Description copied from interface: CallMetaDataProvider
    Does this database support returning ResultSets that should be retrieved with the JDBC call: Statement.getResultSet()?
    Specified by:
    isReturnResultSetSupported in interface CallMetaDataProvider
    Overrides:
    isReturnResultSetSupported in class GenericCallMetaDataProvider
  - isRefCursorSupported
```
public boolean isRefCursorSupported()
```
    Description copied from interface: CallMetaDataProvider
    Does this database support returning ResultSets as ref cursors to be retrieved with CallableStatement.getObject(int) for the specified column.
    Specified by:
    isRefCursorSupported in interface CallMetaDataProvider
    Overrides:
    isRefCursorSupported in class GenericCallMetaDataProvider
  - getRefCursorSqlType
```
public int getRefCursorSqlType()
```
    Description copied from interface: CallMetaDataProvider
    Get the Types type for columns that return ResultSets as ref cursors if this feature is supported.
    Specified by:
    getRefCursorSqlType in interface CallMetaDataProvider
    Overrides:
    getRefCursorSqlType in class GenericCallMetaDataProvider
  - metaDataSchemaNameToUse
```
public String metaDataSchemaNameToUse(String schemaName)
```
    Description copied from interface: CallMetaDataProvider
    Provide any modification of the schema name passed in to match the meta-data currently used. The returned value will be used for meta-data lookups. This could include altering the case used or providing a base schema if none is provided.
    Specified by:
    metaDataSchemaNameToUse in interface CallMetaDataProvider
    Overrides:
    metaDataSchemaNameToUse in class GenericCallMetaDataProvider
  - createDefaultOutParameter
```
public SqlParameter createDefaultOutParameter(String parameterName,
                                              CallParameterMetaData meta)
```
    Description copied from interface: CallMetaDataProvider
    Create a default out parameter based on the provided meta-data. This is used when no explicit parameter declaration has been made.
    Specified by:
    createDefaultOutParameter in interface CallMetaDataProvider
    Overrides:
    createDefaultOutParameter in class GenericCallMetaDataProvider
    Parameters:
    parameterName - the name of the parameter
    meta - meta-data used for this call
    Returns:
    the configured SqlOutParameter
  - byPassReturnParameter
```
public boolean byPassReturnParameter(String parameterName)
```
    Description copied from interface: CallMetaDataProvider
    Should we bypass the return parameter with the specified name. This allows the database specific implementation to skip the processing for specific results returned by the database call.
    Specified by:
    byPassReturnParameter in interface CallMetaDataProvider
    Overrides:
