Procedures in oracle with simple examples
Send us your comments.
Oracle makes a distinction between "invokers" (a user executing a stored procedure) and "definers" (the user under which the create procedure statement was issued).The collection type list_of_numbers referenced here is defined by: create OR replace type list_of_numbers AS varray(50) OF number; The body of the package is shown below.Stored Procedure Input and Output When calling an Oracle stored procedure, all input and output data is passed as arguments to the procedure.Stored procedures are beneficial when we are dealing with multiple tables with complex scenario and rather than sending multiple queries to the database, we can send required data to the stored procedure and have the logic executed in the database server itself.The procedure will lookup the course_number based on course name.The following PHP script illustrates this procedure:?php conn oci_connect scott tiger or die; sql 'begin test num_entries, :blog_entries END stmt oci_parse(conn, sql / Bind the input num_entries argument to the max_entries PHP variable max_entries 5; / Create a new cursor resource blog_entries 20th century bold font oci_new_cursor(conn / Bind.The second step, after you have executed the SQL statement, is calling oci_execute on the cursor resource.Sql 'begin sayHello name, :message END You then bind the parameters to PHP variables with calls to oci_bind_by_name.OCI8 extension 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.
