Using Dynamic Queries
In Spring Data JPA, a dynamic query refers to a type of query that is constructed at runtime based on various conditions or parameters. Dynamic queries are particularly useful when you need to build and execute queries that can vary based on user input or changing criteria. Instead of writing a static query with fixed criteria, you create a query that adapts to different scenarios.
Dynamic queries can be constructed using the Criteria API, or by creating the query statement dynamically using JPQL or Native SQL. The Criteria API provides a programmatic and type-safe way to define queries to the database.
In previous recipes, we used the naming convention of the JpaRepositories when creating the repository methods. Spring Data JPA generates the queries dynamically using the same mechanism we will explain in this recipe.
In this recipe, we will implement the following functionalities:
- Search players using different criteria, for instance by name...
