To declare a cursor variable, you use the REF CURSOR is the data type. PL/SQL has two forms of REF CURSOR typeS: strong typed and weak typed REF CURSOR. The following shows an example of a strong REF CURSOR. REF CURSOR types may be passed as parameters to or from stored procedures and functions. The return type of a function may also be a REF CURSOR type.
change like this remove the return. CREATE OR REPLACE PACKAGE HR. SP_PACKAGE AS TYPE dept_type IS REF CURSOR ; END
Ask Question I have a requirement to have a IN OUT parameter along with a reference cursor as a return from a stored REF CURSOR isn't a type in itself. To pass these, you can either: - Use the predefined sys_refcursor type - Define your own type of REF CURSOR For example, the following defined the parameter as a sys_refcursor. If you want to access the values in SQL*Plus / SQL Dev, pass a refcursor variable: PROC b (no commits or OUT parameters) PROC c (REF CURSOR OUT parameter and commits) "A" calls "b" using a DBLINK works fine. "A" calls "b" and "b" calls "c" does not work(ORA-02064) Other than removing the COMMIT statements in proc C do you see any other workaround for this problem.
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:
First we create an SQL type to contain a list of numbers CREATE TYPE LIST_NUMBER AS TABLE OF NUMBER(10); / Next thing to do is add a custom type and function header to the package … Download source Oracle tables used in this example from the following link Download Scott Schema script..
The following Oracle procedure will take the two parameters, (1) i_empno as IN parameter employee number and (2) o_total_salary as OUT parameter to return the total salary of the employee.
All you need to change in the examples to make them work for user defined REF CURSOR s is the declaration use of cursor parameters TomPlease could you provide guidelines on the use of cursor parameters. I have read that using them allows better resource sharing.e.g.cursor c1 (v_hire_date in emp.hire_date%type) isselect * from emp where hire_date = v_hire_date;is better thancursor c1 isselect * from emp where 9/25/2015 The rqEval function executes the R function in the script specified by the EXP_NAM parameter. You can pass arguments to the R function with the PAR_CUR parameter.. The rqEval function does not automatically receive any data from the database. The R function generates the data that it uses or it explicitly retrieves it from a data source such as Oracle Database, other … 5/5/2008 OPEN v_data cursor FOR SELECT * FROM my_view WHERE v_security_id = bond_security_id AND v_date = dated; END; I have removed the ref cursor out parameter declared in Oracle , as in Mysql you can cannot pass a cursor as an out parameter. My question is how can I access this cursor in a java program that is returned by my mysql procedure . Oracle Database Tips by Donald BurlesonJuly 12, 2015 .
It is useful when writing general-purpose and flexible programs like ad hoc query systems, when writing programs that must execute DDL statements, or when you do not know at compilation time the full text of a SQL statement or the number or data types of its input and output OPEN-FOR-USING Statement. 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.
This provides the capability to modularize the operations on a cursor into separate programs by passing a cursor variable between programs. Cursor Variables. 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.
stored procedure with REF CURSOR or SYS_REFCURSOR. What is difference between REF CURSOR and SYS_REFCURSOR? Execute/Test stored procedure with primitive type:- Contains three examples that demonstrate using REF CURSORs. Parametry REF CURSOR v čtečce OracleDataReader REF CURSOR Parameters in an OracleDataReader Ukazuje, jak spustit uloženou proceduru PL/SQL, která vrací parametr REF CURSOR, a přečte hodnotu jako OracleDataReader. 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.aktualizovat mé přání aplikace

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."
Cursor without parameters (simplest) Declaring a cursor without any parameters is the simplest cursor. Let's take a closer look. Syntax. The syntax for a cursor without parameters in Oracle/PLSQL is: CURSOR cursor_name IS SELECT_statement; Example. For example, you could define a cursor called c1 as below. 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 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).
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?
