    • assignRowValues

      boolean assignRowValues​(ResultSet receiver, long currentRow) throws SQLException
      This method is called once for each row that should be returned from a procedure that returns a set of rows. The receiver is a SingleRowWriter instance that is used to capture the data for the row.

      If the return type is RECORD rather than a specific complex type, SQL requires a column definition list to follow any use of the function in a query. The ResultSetMetaData of receiver can be used here to learn the number, names, and types of the columns expected by the caller. (It can also be used in the case of a specific complex type, but in that case the names and types are probably already known.)

      Specified by:

      receiver - Receiver of values for the given row.
      currentRow - Row number, zero on the first call, incremented by one on each subsequent call.
      Returns:

      Throws:
      SQLException
