This may, in turn, cause you to subsequently wonder just what a query work area is.A query work area can be thought of as the result set (sometimes also referred to as a row set) on the serverit is the location where the results of a query are stored in server memory.When you start reading terms such as "query work area" and "memory address," you may begin to think that ref cursors are complicated and require dealing with C-style pointers and the like. NET, you can think of a ref cursor as nothing more than a handle to a result set on the server.Fortunately, this is not the case with Oracle Data Provider for . Because a ref cursor is a PL/SQL datatype, you do need some way of representing the ref cursor in your .The users need the appropriate permissions to execute the PL/SQL procedure or function for this scenario to work correctly, but these can be granted by the database administrator.In addition, by using PL/SQL, you are moving code that deals with the data into the database and separating the client logic from the data logic.
For example, suppose you have a requirement to first collect some information from your application’s users and then insert that information into a table in Oracle Database. But what if the data collected corresponds to multiple rows in the table rather than a single row?
Another benefit that is sometimes overlooked is that you can use PL/SQL as a security tool or mechanism.
It's possible to create a PL/SQL procedure that returns data from a database table to which users have no direct access and are thus unable to browse with an external toolthey can get to the data only via the PL/SQL code.
Create Command(); // the sql text used to insert the // rows in the arrays and this // necessarily uses bind variables cmd. One difference between these two array approaches is the supported parameter types.
Command Text = "insert into jobs (job_id, " "job_title, " "min_salary, " "max_salary) " "values (:1, :2, :3, :4)"; // set the number of elements // in the arrays and all three // arrays are the same size cmd. The array binding technique illustrated here supports more typesincluding XMLType, LOB, and Time Stampthan PL/SQL associative arrays.

Moving the code into the database implicitly centralizes it, so it needs to be managed only in a single location. 174, Abel, Ellen, 11-MAY-1996 166, Ande, Sundar, 24-MAR-2000 130, Atkinson, Mozhe, 30-OCT-1997 105, Austin, David, 25-JUN-1997 In Get Cursor Parameter...
