  • Field Details

  • Method Details

    • apply

      T apply(ResultSet rs, List<String> columnLabels) throws SQLException
      In a lot of scenarios, including PreparedQuery/Dao/SQLExecutor, the input ResultSet will be closed after apply(rs) call. So don't save/return the input ResultSet.
      Specified by:
      apply in interface com.landawn.abacus.util.Throwables.BiFunction<ResultSet,List<String>,T,SQLException>
      Parameters:
      rs -
      columnLabels -
      Throws:
      SQLException
