Oracle stored procedure is a kind of precompiled PL/SQL code, which is stored in the database and can be reused. Stored procedures can reduce network traffic and improve performance because it centralizes business logic in the database rather than in client code.
In Oracle database, deleting stored procedures is also a very common task. This article explains how to delete stored procedures.
First, let’s take a look at the basic syntax of a stored procedure:
CREATE [OR REPLACE] PROCEDURE procedure_name (argument1 IN datatype1, argument2 IN datatype2, ..., argument_n IN datatype_n) IS -- variable declarations BEGIN -- statements END;
Where, procedure_name
is the name of the stored procedure, argument1
to argument_n
is the input parameter of the stored procedure, datatype1
to datatype_n
is the data type of the input parameter, variable declarations
is the variable declared in the stored procedure , statements
is the code executed by the stored procedure.
To delete a stored procedure, you can use the DROP statement:
DROP PROCEDURE procedure_name;
This will delete the stored procedure named procedure_name
. If the stored procedure does not exist, an error message will appear.
To delete a stored procedure, perform the following steps:
Step 1: Connect to your Oracle database.
Step 2: Use the following SQL statement to find the name of the stored procedure you want to delete:
SELECT object_name FROM user_objects WHERE object_type = 'PROCEDURE';
This will list all stored procedures. Find the name of the stored procedure you want to delete in this list.
Step 3: Use the DROP PROCEDURE statement to delete the stored procedure:
DROP PROCEDURE procedure_name;
Note: Before executing the DROP PROCEDURE statement, be sure to back up your data.
In the Oracle database, stored procedures are an important component. When deleting a stored procedure, make sure you know the impact the stored procedure has on your application or database.
