registerOutParameter for table?

[meera rao]

I have a record and table of type this record



TYPE owner_Rec IS RECORD (

ssn CHAR (9),
NAME VARCHAR2 (60),
address VARCHAR2(120) );

TYPE Owner_tbl IS TABLE OF owner_Rec
INDEX BY BINARY_INTEGER;

This I am sending as an out parameter in my stored procedure.

How should i access this table in my java code , what should i mention in registerOutParameter

cs = (OracleCallableStatement) conn.prepareCall("{call GET_OWNER(?)}");

cs.registerOutParameter (1, );

See the Object Example on OTN. It demonstrates two ways to do this.

This link is not available now. I am looking for the same solution. I want the solution exactly for this question in this thread. Can anyone provide the similar solution that was in this link?

There is a page on this topic here on the Ranch. It only lists the caveats, but there is also a link on that page to a thread where one of our users posted code which worked for him. And of course, as a last resort, links to documentation.

I am posting the solution for the appraoch i used. Just might be useful for someone in the future:

If you are using oracle.sql.ARRAY or STRUCT to represent the OUT Parameter in callable statement, ten you should register the out parameter along with the sql type name defined in the DB.

Find the below code in which Employee is represented as STRUCT, and the EMPLOYEE_LIST as ARRAY .

CREATE OR REPLACE TYPE EMPLOYEE AS OBJECT
(name varchar2(50),address varchar2(50),empId number,role varchar2(50)); 


CREATE OR REPLACE TYPE EMPLOYEE_LIST AS TABLE OF EMPLOYEE;

 Class.forName ("oracle.jdbc.driver.OracleDriver");
	  	
	  	      // Connect to the database  	  
	  	      conn = DriverManager.getConnection ("url:username:password");
		
                                   Vector vector = new Vector();// to hold all the STRUCTs - i.e., EMPLOYEEs

		Object[] attr = new Object[4];
		
		attr[0] = (Object) new String("Iqzas");
		attr[1] = (Object) new String("E33");
		attr[2] = (Object) new BigDecimal(12);
		attr[3] = (Object) new String();

		
		

		StructDescriptor structdesc = StructDescriptor.createDescriptor("EMPLOYEE",conn);
		
		//ArrayDescriptor structdesc = ArrayDescriptor.createDescriptor("PKG.EMPLOYEE",conn);

		vector.add((Object)new STRUCT(structdesc, conn, attr));
		
		//vector.add((Object)new ARRAY(structdesc, conn, attr));


		ArrayDescriptor arraydesc = ArrayDescriptor.createDescriptor("EMPLOYEE_LIST",conn);
	
		Object obj_array[] = vector.toArray();
		ARRAY array = new ARRAY(arraydesc,conn,obj_array);
		

		CallableStatement cstmt = conn.prepareCall("{? = call PKG.GET_EMPLOYEES(?,?,?,?,?) }"); // this sql function returns EMPLOYEE_LIST type.
		
		cstmt.setInt(4, 11);
		cstmt.setString(2, "Mohamed");
		cstmt.setString(3, "Iqzas");
		cstmt.setString(5, null);		

		((OracleCallableStatement)cstmt).setARRAY(6, array);

		cstmt.registerOutParameter(1, OracleTypes.ARRAY, "EMPLOYEE_LIST"); //for which we are representing arrays.
		cstmt.execute();
		ARRAY resultArray = (ARRAY)cstmt.getObject(1);
		System.out.println(resultArray.length());
		Object[] resultStructArray = (Object[])resultArray.getArray();
		STRUCT resultElement = (STRUCT)resultStructArray[0];
		System.out.println(resultStruct.length+"From First Element:"+resultElement.getAttributes()[0]);//prints out first attribute - name of the employee. :-)
