12/4/2023 0 Comments Tableplus show stored procedureNow that you have created both the tables, start creating the stored procedure in SQL with the syntax mentioned earlier. INSERT INTO CarDescription VALUES (501,'High-performance sports car from the German manufacturer') INSERT INTO CarDescription VALUES (401,'Luxury SUV from the Italian automotive') INSERT INTO CarDescription VALUES (301,'Luxury sports car from the Italian manufacturer') INSERT INTO CarDescription VALUES (201,'Luxury motorcycle from the German automotive') INSERT INTO CarDescription VALUES (101,'Luxury vehicle from the German automotive') Now create the second table named CarDescription. INSERT INTO Car VALUES (401,'Lamborghini') INSERT INTO Car VALUES (101,'Mercedes-Benz') You will also insert some values in them using the INSERT INTO command. But before that, create two tables using the CREATE TABLE command that you will use throughout the article. You will use the syntax to create a simple stored procedure in SQL. ![]() Note: You will work with and look at examples for different parameters in this article. Thus, it receives from, as well as sends a value to the program IN OUT: It is the combination of both IN and OUT.OUT: It will send output value to the program.IN: It is the default parameter that will receive input value from the program.In the syntax mentioned above, the only thing to note here are the parameters, which can be the following three types: The syntax of SQL stored procedure is:ĬREATE or REPLACE PROCEDURE name(parameters) How to Create a Simple Stored Procedure in SQL?Ĭreating a stored procedure in SQL is as easy as it can get. Increases performance: Upon the first use, a plan for the stored procedure is created and stored in the buffer pool for quick execution for the next time.Low network traffic: The server only passes the procedure name instead of the whole query, reducing network traffic. ![]() Security: Stored procedures allow you to enhance the security of an application or a database by restricting the users from direct access to the table.Easy to modify: You can quickly change the statements in a stored procedure as and when you want to, with the help of the ALTER TABLE command.Reusable: As mentioned, multiple users and applications can easily use and reuse stored procedures by merely calling it.Stored procedures provide some crucial benefits, which are: In Relational Database Management Systems (RDBMS), a stored procedure is a batch of prepared SQL code grouped as a logical unit that you store in the database.What are the Benefits of using a Stored Procedure in SQL? Stored procedures allow reusability of SQL code. In this post, I will explain how to call MySQL stored procedures from a Spring Boot application. Ĭalling Stored Procedure from Spring Boot Example Dependencyįor the application in this post, add the Spring Data JPA starter and the MySQL connecter dependency in your Maven pom.xml file. The application contains a Blog entity class.īlog.java class Blog = long String Integer yearOfPost I will demonstrate calling stored procedures with a Spring Boot application with the controller, service, and repository layers. The next step is to create a stored procedure to be referred to from the entity class. The SQL code of a stored procedure to retrieve all blogs is this. You can run the preceding stored procedure using a MySQL client. I have used MySQL Workbench to create a stored procedure named getAllBlogs. The getAllBlogs procedure takes no parameter and returns all the records of the blog table. The next step is to call the stored procedure. ![]() ![]() Import = "getAllBlogs",procedureName = "getBlogsByTitle", procedureName = "getBlogsByTitle", parameters = ParameterMode.IN,name = "tblogTitle",type=String.class)} )}) To use this annotation, I have refactored the Blog entity class, like this.īlog.java package Approach 1 – AnnotationĪ defines a query that calls stored procedures as named queries. In the preceding Blog class, there are two annotations. Notice that the annotation groups both the annotations. In a annotation, the name attribute specifies the name of the query. The procedureName attribute specifies the name of the stored procedure to call. The second annotation on Line 9 specifies the mode, name, and type of the parameter to be passed to the stored procedure.
