Procedure returns a final output generated by SQL Statements. When we declare an IN type parameter, theĪpplication must pass an argument to the stored procedure. The MySQL Stored procedure parameter has three modes: IN, OUT, and INOUT. In MySQL Workbench, You can view the stored procedure under the Stored Procedures folder The script is applied successfully, and a stored procedure sp_GetCustomer has been created
#MYSQL WORKBENCH MARIADB CODE#
On the Review the script screen, you can view the code A dialog box, Apply script to database opens. Select store_id, first_name, last_name, email, create_date, last_update from customerĬlick on Apply. The code of the procedure is the following: The output should contain film_id, title, description, release year,Īnd rating column. Suppose you want to populate the list of films. For demonstration, I am using the sakila database.
If the procedure has the parameters, then the parameter values must be specified in the parenthesis The procedure name must be specified after the CALL keyword To execute the store procedure, you can use the CALL keyword. The SQL Queries and code must be written between BEGIN and END keywords The parameter list must be comma-separated The name of the procedure must be specified after the Create Procedure keywordĪfter the name of the procedure, the list of parameters must be specified in the parenthesis. The syntax to create a MySQL Stored procedure is the following:Ĭreate Procedure (,, ) The stored procedure helps to prevent the database from SQL Injection Granted to the user to execute the stored procedure without giving permission to the tables used in the stored Secure: The stored procedures are more secure than the AdHoc queries.Need to make a change in the stored procedure only This way, a stored procedure makes the database more consistent. We can implement the business logic withinĪn SP, and it can be used by applications multiple times, or different modules of an application can use the Easy to maintain: The stored procedure are reusable.When you execute it, instead of sending multiple queries, we are sending only the name and the parameters of the Reduce the Network Traffic: Multiple SQL Statements are encapsulated in a stored procedure.
The stored procedure can alsoĮxecute another stored procedure or a function that modularizes the code.įollowing are the benefits of a stored procedure: Stored procedure may contain a conditional statement like IF or CASE or the Loops. The stored procedure is SQL statements wrapped within the CREATE PROCEDURE statement. In this article, I am covering theīasics of the stored procedure that includes the followingĬreate a stored procedure using Query and MySQL workbenchĭrop the Stored Procedure using query and MySQL workbench In this article, we are going to learn about the stored procedures in MySQL.
