      Description

      I was trying to do some performance improvements on on of my LOB operations and reducing the amount of I/O with the database utilizing result sets, specifically updating result sets.

      However, I got Updates are not supported most likely from https://github.com/MariaDB/mariadb-connector-j/blob/master/src/main/java/org/mariadb/jdbc/internal/com/read/resultset/SelectResultSet.java#L2276

      If updates are not supported (which is kind of lousy) you should be able to fail it sooner specifically from detecting if ResultSet.CONCUR_UPDATABLE was passed on the prepared statement. e.g. from my code base:

      PreparedStatement selectStmt =
      c.prepareStatement("SELECT NAME, CHUNKSEQUENCE, CHUNK, LASTUPDATEDON FROM LOBDATA where NAME = ? order by CHUNKSEQUENCE",
      ResultSet.TYPE_FORWARD_ONLY,
      ResultSet.CONCUR_UPDATABLE);
