![]() ![]() The basic syntax of creating a stored procedure in MySQL database is shown below: DELIMITER &ĬREATE PROCEDURE PROCEDURE_NAME (PARAMETER_1, PARAMETER_2, PARAMETER_N.) Once you have created a test_db database, products table, a test_user, and added some sample products, you can now move on to creating the first stored procedure.Ĭreating a Stored Procedure Stored Procedure Syntax | 2 | OPTICAL MOUSE | COMPUTER ACCESSORIES | | 1 | GAMING KEYBOARD | COMPUTER ACCESSORIES | | product_id | product_name | category_name | Your sample products should listed as shown below: +-+-+-+ confirm if the sample products were inserted successfully to the database by running the Select command below: SELECT * FROM products You should get the below output after executing each Insert statement: Query OK, 1 row affected (0.00 sec) INSERT INTO products (product_id, product_name, category_name) VALUES ('6', 'DVB-T2 RECEIVER', 'ELECTRONICS') INSERT INTO products (product_id, product_name, category_name) VALUES ('5', '32 INCH TV', 'ELECTRONICS') INSERT INTO products (product_id, product_name, category_name) VALUES ('4', 'STEREO SYSTEM', 'ELECTRONICS') INSERT INTO products (product_id, product_name, category_name) VALUES ('3', 'MOUSE PAD', 'COMPUTER ACCESSORIES') INSERT INTO products (product_id, product_name, category_name) VALUES ('2', 'OPTICAL MOUSE', 'COMPUTER ACCESSORIES') You can now add a few products to the products table by executing the commands below one by one: INSERT INTO products (product_id, product_name, category_name) VALUES ('1', 'GAMING KEYBOARD', 'COMPUTER ACCESSORIES') Next, switch to the test_db database: USE test_db Ĭreate a products table to store sample records: CREATE TABLE products(product_id BIGINT PRIMARY KEY, product_name VARCHAR(50), category_name VARCHAR(50) ) ENGINE=INNODB Output: Query OK, 0 rows affected (0.01 sec) Grant the test_user full privileges to the test_db database GRANT ALL PRIVILEGES ON test_db.* TO Query OK, 1 row affected (0.01 sec) Guidelines for MySQL passwords: CREATE USER IDENTIFIED BY 'PASSWORD' Replace PASSWORD with a complex and unique value that follows the Output: Query OK, 1 row affected (0.01 sec)Ĭreate a database user and grant full access to the test_db database. mysql >Įnter the command below to create a test_db database: CREATE DATABASE test_db Next, you will see a MySQL prompt similar to the one shown below. You will be prompted to enter the root password of your MySQL database. Log into the MySQL server: mysql -u root -p You will also populate the table with sample data for testing purposes.
