The code for the BlogRepository interface is this.

At runtime, Spring Data JPA provides implementations of the repository interfaces you create. In Spring Data JPA, repositories are interfaces that declare database operations. We will now create the Spring Data JPA repository interface. REF_CURSOR: for cursors on a result set.The stored procedure modifies and returns back the parameter to the caller. This parameter is initialized by the caller. INOUT: is a combination of IN and OUT parameters.You can use four different modes of parameters to implement a stored procedure: The second annotation on Line 9 specifies the mode, name, and type of the parameter to be passed to the stored procedure. The procedureName attribute specifies the name of the stored procedure to call.

In a annotation, the name attribute specifies the name of the query. Notice that the annotation groups both the annotations. In the preceding Blog class, there are two annotations. Import = 'getAllBlogs',procedureName = 'getBlogsByTitle', procedureName = 'getBlogsByTitle', parameters = ParameterMode.IN,name = 'tblogTitle',type=String.class)} )}) Is there a statement that can drop all stored procedures in MySQL Alternatively (if the first one is not possible), is there such thing as temporary stored. 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. The next step is to call the stored procedure. The getAllBlogs procedure takes no parameter and returns all the records of the blog table. I have used MySQL Workbench to create a stored procedure named getAllBlogs. You can run the preceding stored procedure using a MySQL client. The SQL code of a stored procedure to retrieve all blogs is this. The next step is to create a stored procedure to be referred to from the entity class. The application contains a Blog entity class.īlog.java class Blog = long String Integer yearOfPost The column in question is CreatedDate, which is set when my item is created, but its being changed by a stored procedure. I will demonstrate calling stored procedures with a Spring Boot application with the controller, service, and repository layers. Find all stored procedures that reference a specific column in some table Asked 9 years, 7 months ago Modified 2 months ago Viewed 249k times 68 I have a value in a table that was changed unexpectedly. 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.

In this post, I will explain how to call MySQL stored procedures from a Spring Boot application. Stored procedures allow reusability of SQL code. It contains one row for each function and stored procedure in the database for which the current user has rights. 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.
