```
void initializeWithMetaData(DatabaseMetaData databaseMetaData)
                     throws SQLException
```
    Initialize using the provided DatabaseMetData.

    SQLException - in case of initialization failure
  - initializeWithProcedureColumnMetaData
```
void initializeWithProcedureColumnMetaData(DatabaseMetaData databaseMetaData,
                                           @Nullable

                                    throws SQLException
```
    Initialize the database specific management of procedure column meta-data. This is only called for databases that are supported. This initialization can be turned off by specifying that column meta-data should not be used.
    参数:
    databaseMetaData - used to retrieve database specific information
    catalogName - name of catalog to use (or null if none)
    schemaName - name of schema name to use (or null if none)
    procedureName - name of the stored procedure
    抛出:
    SQLException - in case of initialization failure

    Does this database support returning ResultSets as ref cursors to be retrieved with CallableStatement.getObject(int) for the specified column.
  - getRefCursorSqlType
```
int getRefCursorSqlType()
```
    Get the Types type for columns that return ResultSets as ref cursors if this feature is supported.

```
boolean isProcedureColumnMetaDataUsed()
```
    Are we using the meta-data for the procedure columns?
  - byPassReturnParameter
```
boolean byPassReturnParameter(String parameterName)
```
    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.
