PL/SQL REF CURSOR and OracleRefCursor, Server → 9.5 → User Guides → Database Compatibility for Oracle® Developer's Guide 4 Stored Procedure Language : 4.9 REF CURSORs and Cursor Variables REF CURSOR types may be passed as parameters to or from stored a cursor into separate programs by passing a cursor variable between programs. An IN OUT REF CURSOR parameters. Because the Oracle Database adapter models IN REF CURSOR parameters as strings and OUT REF CURSOR parameters as complex types, it cannot support a single type for an IN OUT REF CURSOR parameter.

The OPEN-FOR-USING statement associates a cursor variable with a query, executes the query, identifies the result set, positions the cursor before the first row in the result set, then zeroes the rows-processed count kept by %ROWCOUNT. Example: Returning a REF CURSOR from a procedure (PL/SQL) This example demonstrates how to define and open a REF CURSOR variable, and then pass it as a procedure parameter. The cursor variable is specified as an IN OUT parameter so that the result set is made available to the caller of the procedure: Corresponding formal and actual cursor variable parameters must have compatible return types. Otherwise, PL/SQL raises the predefined exception ROWTYPE_MISMATCH. To pass a cursor variable parameter between subprograms in different PL/SQL units, define the REF CURSOR type of the parameter in a package. When the type is in a package, multiple Jul 13, 2012 · I'm currently using Oracle 11.2G and I was wondering if you can declare a dynamic cursor as a strong ref cursor type or can it only be declared as weak type ref cursor? Now, if it can only be declared as a weak type ref cursor, is there any way to avoid having to explicitly declare the type and field names being returned by the cursor?

I apologize for the email sended uncompletely. By the way , I suggest that improve the interface of this page, yesterday, after i typed some stuff, i used to type the TAB key and the cursor located in TAB key, and my information just sent out. I've a package, one of whose procedures takes in half-a-dozen parameters and outputs a ref cursor (plus a number and varchar2 OUT parameter, too). The value of second parameter is a string that specifies a SQL statement that describes the column names and data types of the data.frame returned by rqEval. The value of third parameter is the name of the script in the Oracle R Enterprise R script repository.-- Create a script named myRandomRedDots2 and add it to the R script repository. I've a package, one of whose procedures takes in half-a-dozen parameters and outputs a ref cursor (plus a number and varchar2 OUT parameter, too). SQL> CREATE OR REPLACE PROCEDURE 2 FETCH_EMPLOYEES_NAMES(V_DeptNo NUMBER, V_REF OUT SYS_REFCURSOR ) 3 /*Note: SYS_REFCURSOR as parameter type used here because it has been declared in standard package it is a ref cursor */ 4 IS 5 Begin 6 OPEN V_REF For Select FIRST_NAME, LAST_NAME From EMP_TEST where DEPTNO = V_DeptNo; 7 End FETCH_EMPLOYEES_NAMES; 8 / Procedure created.

A cursor is passed a parameter in very much the same way a procedure is passed a parameter except that the parameter can only be IN mode. Like the procedure, the cursor definition will declare an unconstrained datatype for the passed variable. Use SYS_REFCURSOR as parameter type. SQL> SQL> SQL> CREATE TABLE orders( order_number NUMBER, 2 create_date DATE, 3 assign_date DATE, 4 close_date DATE); SQL> SQL> BEGIN 2 FOR counter IN 1..3 LOOP 3 INSERT INTO orders 4 VALUES(counter, 5 SYSDATE, 6 SYSDATE + 1, 7 SYSDATE + 2); 8 END LOOP; 9 END; 10 / PL/SQL procedure successfully completed.

And note that a function that returns an out parameter is considered bad practice and should be avoided. From the Oracle documentation: "Do not use OUT and IN OUT for function parameters. Ideally, a function takes zero or more parameters and returns a single value. A function with IN OUT parameters returns multiple values and has side effects."

To execute a multi-row query, Oracle opens an unnamed work area that stores processing information. You can access this area through an explicit cursor, which names the work area, or through a cursor variable, which points to the work area. call it once only in the cursor, because i need the return value and the out parameter.
