code: @Override
      public void setFetchSize(int rows) throws SQLException
      {
          checkClosed();
          if (rows < 0) {
              throw SQLError.get(SQLError.ILLEGAL_ARGUMENT, rows);
          }
          this.fetchSize = rows;
      }
docs: Gives the JDBC driver a hint as to the number of rows that should be fetched from the database when more rows are needed for ResultSet objects genrated by this Statement.
