Also, we'll have to go through the connector's executor somehow.
The Generic JDBC Connector is meant to be used only for JDBC compliant databases, so non JDBC based sources will have to came up with their own connector. I'm still not sure if the PreparedStatement will work for example on query "INSERT INTO table VALUES(?, ?,?)" that might be entered by user in the export case. Perhaps we should disable export with custom query for now and re-add it later after we figure out how to get schema for it.

Make sense, let's just ensure that we will create follow up JIRAs for it later. - Jarek ----------------------------------------------------------- This is an automatically generated e-mail.
