So to get a result set out of an Oracle stored procedure, you have to pass it as an output parameter, and the type of the parameter is REF CURSOR. In this week tutorial 10 as part of Oracle 9i SQL and PL/SQL training explains about the Introduction to Cursors, different types and the Cursors and Loops with sample code and screen shots. Need of the cursor is Many times, when a query returns more than one row. Need some way of doing this through a named sql query to support. Each time you open the cursor, you can pass different arguments to the cursor, which results in different result sets. OUT REF CURSOR. stored procedure with scalar type - NUMBER, VARCHAR 2.

For example, When you execute INSERT, UPDATE, or DELETE statements the cursor attributes tell us whether any rows are affected and how many have been affected. This example shows how to call Oracle stored procedures with ref_cursor out parameter. This is a write-only parameter i. This procedure also has two output parameters. * Another difference is a ref cursor can be passed from subroutine to subroutine -- a cursor cannot be. stored procedure with scalar type - NUMBER, VARCHAR 2. 1 Package declarations for types are: type t_num_rec is record ( num number ); type t_num_rec_tbl is table of t_num_rec; type c_num_rec_tbl is ref cursor return t_num_rec; In procedure I declare output parameter like: x_new_event_id_cur out c_num_rec_tbl and table variable like: v_new_event_id_tbl t_num_rec_tbl; and then after populating it I do like: open x_new_event_id_cur for select * from table(v_new_event_id_tbl); -- I got the same: Cursor. For a pipelined function to be parallel-enabled, however, it must take its source dataset from a ref cursor parameter (rather than have a static cursor defined inside the PL/SQL). In an Oracle stored procedure declaration, you are not permitted to constrain CHAR and VARCHAR2 parameters with a length, and NUMBER parameters with a precision or scale, or both. 6) A regular cursor can more efficiently retrieve data than ref cursor.

REF CURSOR can be returned from a stored procedure as an OracleDataReader via an output parameter defined as OracleType. Stored routine parameter types have the same constraint as the table and view columns - they should be primitive non-object types. This is an added feature that comes with PL/SQL v2. The result set is returning a false statement and did not return any value. The type of the result set returned depends on whether the REF CURSOR parameter is declared as a strongly-typed or weakly-typed REF CURSOR in the stored procedure or function definition on the Oracle server. TIMESTAMP values with or without time zone are handled correctly. Return the > REF CURSOR as an OUT parameter. SYS_REFCURSOR. Drag the GET_DEPT_PROC to the diagram sheet. This procedure also has two output parameters. This time, its position is just among the other parameters in the query. 3 the REF CURSOR type has been available to allow recordsets to be returned from stored procedures and functions. ResultSet, resultMap=departmentResultMap} The "resultMap" attribute specifies the name of the result map that. The return type of a function may also be a REF CURSOR type. Need some way of doing this through a named sql query to support. The code for the stored procedure is as follows: create or replace package testpack as type MyCursor is ref cursor; procedure testproc(Ref_Cur_1 out MyCursor); end; create or replace procedure testproc (Ref_Cur_1 in out cursor) as begin open Ref_Cur_1 for select * from customer; end;. When I try to ExecuteDataset method. A procedure may or may not return any value. Cursor參數,問題解決!.

But not the REF CURSOR ones! //Hardcoding the value of i/p paramter in this example _variant_t vt;. The current thoughts are that you should execute at least a dummy query and avoid returning an uninitialized REF CURSOR. StoredProcedureQuery createStoredProcedureQuery(String procedureName, Class resultClasses). Here is my environment. TYPE CURSOR_NAME IS REF CURSOR [RETURN return_type]; CURSOR_VARIABLE CURSOR_NAME; Return clause is optional with REF CURSOR type statement. Using this hint tells Oracle to make a call by reference. Oracle will stop updating file headers, but will continue to write data to the database files even if a tablespace is in backup mode.

The adapter supports the use of the REF data type (cursor) as an OUT parameter only in an Oracle stored procedure. As an option you can slightly redesign a procedure and pass the cursor name as a parameter, so the caller always knows which cursor to fetch: -- Procedure that returns a cursor (its name specified as the parameter) CREATE OR REPLACE FUNCTION show_cities2 (ref refcursor) RETURNS refcursor AS $$ BEGIN OPEN ref FOR SELECT city, state FROM cities. We can provide a suitable name for the cursor. Create or Replace PROCEDURE sp_GetUsers(output1 out cursorType,input1 in number) is. (You cannot use this method with Oracle's ThinClient JDBC drivers.

Iam unable to get those data , iam getting null after calling the procedure. the invocation of an oracle stored procedura with REF CURSOR as output parameter raises a NullPointerException. Following method of EntityManager can be used to create an instance of StoredProcedureQuery with resultClasses argument to map records returned by a database cursor:. As in the previous post, I will use IN and OUT parameters in the first and REF_CURSOR in the second example. A function must return a result set. e, we cannot pass values to OUT paramters while executing the stored procedure, but we can assign values to OUT parameter inside the stored procedure and the calling program can recieve this output value. You can't refer to the cursor parameter outside of the SELECT statement associated with the cursor. NET application, and based on the application logic, the application passes this REF CURSOR to. We have few examples below to show how the passing parameters works within Stored. Another extension of the DB API 2. REMARK REMARK comment or --comment-- or /* comment */ RUN Execute (or re-execute) commands in the SQL*Plus buffer Lists the commands before running.
