Question

I have complex procedures in oracle package with complex in/out parameters. I will show one of the my procedures in following :

 PROCEDURE Authorize(PO_ErrorCode         OUT NUMBER,
                     PO_ErrorText         OUT VARCHAR2,
                     PI_Count             IN NUMBER,
                     PI_Setting           IN Setting,
                     PI_InputData         IN InputData,
                     PO_PreData           OUT InputData);

and will show two structures Setting and InputData in following:

CREATE OR REPLACE TYPE Setting as object( ProviderType  NUMBER
                                          SwitchCode    NUMBER)

CREATE OR REPLACE TYPE Input_Data Is Table Of MainInputData;

CREATE OR REPLACE TYPE MainInputData as object( itemId            NUMBER,
                                                itemValue         NVARCHAR2(150),
                                                itemEncyptd       NUMBER,
                                                itemEncryptKey    RAW(16));

with above description I have several structure contain : Type, Array, Array of Type and Array of Primitive.

I call this function by jdbc and oracle driver and related classes such as STRUCT& ARRAY but generated a lot of and complex code for this goal.

My question is : Is there utility or framework for do this task by simple code?
I know spring has a jdbc utility but I haven’t experience with it.

Answer 1

You can use spring utility.

There is a class StoredProcedure where can you declare all your input and output parameters and their types inside the constructor using sqlOutParameter and sqlInParameter.

In your case there are 3 input parameters, to pass this you can overwrite execute method with 3 arguments and call

super.execute(a,b,c)
