将用户定义的列表从休眠传递到oracle存储过程

Question

I want to pass a user defined object from my hibernate class and pass it onto a stored procedure which reads this list of objects and does the processing. How can i do the same?

The Class is as follows.

public class ExcelListenerBean {
    private int id;
    private String shortName;
    private String fmrCusip;
    private Double incorrectTrdShares;
    private Double incorrectTrdPrice;
    private String incorrectTrdBuySell;
    private Double incorrectTrdCommRate;
    private Double incorrectTrdCommission;
    private Double incorrectTrdFees;
    private Double incorrectTrdNet;
    private Double correctionTrdShares;
    private Double correctionTrdPrice;
    private String correctionTrdBuySell;
    private Double correctionTrdCommRate;
    private Double correctionTrdCommission;
    private Double correctionTrdFees;
    private Double correctionTrdNet;
    private String currency;
    private String fx;
    private Double netUSD;
    private String notes;
}

Can any one please let me know how to draft the procedure and how to loop through the list of ExcelListenerBean objects and save them to a table.

Answer 1

1. Create OBJECT type , say MyType is OBJECT .... in Oracle that has all the fields you need
2. Create collection type , TableOfMyObject IS TABLE OF MyObjectType
3. Create procedure that takes TableOfMyObject as parameter.

You can use collection variable in SQL statements in your stored procedure like SELECT * FROM TABLE(collection_variable)

I did the same, but the biggest challenge wast to call it from the app using hibernate - I finally found the way to do that.

Update SQL that can be run from Toad.

set serveroutput on; -- for debugging, 
-- it makes sense if your procedure outputs anything
declare my_list TableOfMyObject  := TableOfMyObject ();
begin 
  my_list.extend;
  my_list(1) := MyType([MyType constructor parameters]);

  my_list.extend;
  my_list(2) := MyType([MyType constructor parameters]);
  your_procedure(my_list);
end;
