> In the current implementation, JDBC RowID type is mapped to LongType except for OracleDialect, but there is no guarantee to be able to convert RowID to long.
> The specification of java.sql.RowId says
> "all methods on the RowId interface must be fully implemented if the JDBC driver supports the data type"
> https://docs.oracle.com/javase/8/docs/api/java/sql/RowId.html
> java.sql.RowId declares toString so, we should prefer StringType to LongType.
