You can do that by granting that user the permission to call the stored procedure we created above. Securing data using a Stored ProcedureĪs a database owner or database admin, how can you allow someone to only insert values to the Employees table without being able to do anything else? Confirming the record was added successfully in Arctype. Once you check the Employees table, you will find out that the values that you included when calling the stored procedure have been populated into the table. CALL Insert_Emp_Table(1, 'Bonface', 'WebDev', 23214, 42357, 10000) Using the stored procedure to add a new record. The Employees table we created is empty but we can add data to the table by calling the stored procedure that we just created. $$ The stored procedure to insert values. INSERT INTO employees VALUES (empno, empname, dept, ss_no, acc_no, empsal) Now let's create a stored procedure that inserts values into the Employees table: CREATE PROCEDURE Insert_Emp_Table ( Below is the SQL query for creating the Employees table. The first column will be employee id, the second will be employee name, the third will be employee department, the fourth will be employee social security number, the fifth will be employee account number, and the last column will be employee salary. But before creating and calling a stored procedure, let us create a table of employees that contains six columns. In this article, I will be using PostgreSQL to create and call a stored procedure. That means different databases have different ways of creating and calling a Stored Procedure. The above process of creating and calling a stored procedure is just a general process. The general syntax for creating and calling a stored procedure is as shown below: CREATE PROCEDURE procedure_name AS sql_statement GO Īnd the resulting output is: EXEC procedure_name Stored procedures can also provide an additional layer of protection against SQL Injection. They give better control of permissions which means users can be limited to specific columns and rows in a table. These risks can be avoided by using stored procedures to define things that you want those who have access to the database to do. Disgruntled employees with access to the database can also decide to trash or delete some of your business-critical data. Giving direct access to these tables to anyone is not a good idea because someone can decide to commit fraud or steal personal information to commit identity theft. ![]() Let’s say, for example, that your database has tables with financial data or any sensitive data like social security numbers. This can be helpful in protecting sensitive data in a database. Using stored procedures to limit access to a database makes the process easier to design and manage. That means that someone cannot directly write SQL queries that do what they want to the database table. ![]() Stored procedures can be used to allow access to some parts of a table in a database while denying direct select, insert, update and delete operations against the table. But before I do that, let us go through how stored procedures can be a secure and safe way to give access to your database. In this article, I will show you how to secure data using a stored procedure. Some of the benefits offered by stored procedures are: A stored procedure is a set of SQL statements with an assigned name, which can be stored for later use so it can be reused and shared by multiple programs. ![]()
