Oracle call procedure with out cursor parameter

Basically, your test harness needs to support the definition of a SYS_REFCURSOR variable and the ability to call your procedure while passing in the variable you define then loop through the cursor result set. Call oracle stored procedure with cursor output. Skip to Main Content. An explicit cursor may accept a list of parameters. Each time you open the cursor , you can pass different arguments to the cursor , which in different result sets.

Each one requires a different way of calling as shown below. To create a stored procedure : Open Server Explorer and double-click HR to open the connection to the HR schema created in Connecting to the Oracle Database. Description of the illustration connect_se.

The body section of the cursor and the procedure are implemented in the below package body listing, where the list of first names of the employees passed as input to the procedure is used for limiting the record sets processed by the cursor associated SELECT statement when the cursor is opened with the procedure ’s input parameter as its own. IN and one OUT type parameter HR. How do I create a SQL procedure? What is Oracle stored procedures? Listing 4: The application code calling the function.

You can use the REF CURSOR data type to work with Oracle result set. To retrieve the result set, you must define a REF CURSOR output parameter in a procedure or a function to pass the cursor back to your application. Only the datatype of the parameter is define not its length.

To use a stored procedure with regular out parameters , you should either remove the parameter (if it is possible) or write a little wrapper around the original stored procedure which checks the result of the out parameter and just returns the out ref cursor but no out parameter. NET 10g Release you are now able to easily pass a ref cursor as an input parameter in Oracle Database 10g Release 2. With previous releases of ODP. 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. A stored procedure to print out a “Hello World” via DBMS_OUTPUT. CREATE OR REPLACE PROCEDURE procPrintHelloWorld IS BEGIN DBMS_OUTPUT. But what if I need to call a stored procedure that has both cursor and non- cursor output parameters , as is often the case?

For instance, I am trying to call a stored. As we get more complicate we can declare cursors with parameters. Cursor with parameters. DBUSER table creation script.

For example, you could define a cursor called cas below. 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. This is a write-only parameter i. Parameter name is the same as field name (Toy_Name).

Out parameters for Oracle stored procedures are not supported. Only an OUT REF cursor is supported. Basically, you need to write a wrapper stored procedure that has only one OUT REF cursor and no other OUT parameters. Also note that the stored procedure has both input and output parameters , AND it returns a result set (not via OUT parameters ). The PHP OCIextension provides support for calling stored procedures , allowing you to bind parameters to a procedure statement in the same way as you would to a normal SQL statement, as well as access to result cursors and Oracle collections.

In this topic you will learn how to execute Oracle stored procedures that return SYS_REFCURSOR as out parameters. Suppose, you have two tables named Products and Categories with one-to-many relation.
