This short Spring Data JPA tutorial will teach you how to use the LIKE % expression in a Native SQL Query.
When using advanced SQL LIKE expression, the % sign in the SQL query would represent zero, one or multiple characters. Let’s have a look at the Native JPA SQL Query that uses advanced SQL LIKE expression to select all users whose first_name or last_name in a database table called Users matches the provided keyword.
This tutorial is about Native SQL Queries. For the JPQL code example, read “SQL Query with JPQL in a Spring Boot Application“.
You can also read the following tutorial to learn how to make Hibernate log SQL queries so you can see them.
SQL LIKE % Expression in Native JPA SQL Query
@Query(value="select * from Users u where u.first_name like %:keyword% or u.last_name like %:keyword%", nativeQuery=true) List<UserEntity> findUsersByKeyword(@Param("keyword") String keyword);
In the example above, I am creating a Native JPA SQL Query that uses advanced LIKE expression and Named Parameters. In the SQL query above:
- The :keyword is a named parameter which will be replaced with a value passed in as a method argument annotated with a @Param annotation,
- The named parameter :keyword is surrounded with %, which means that the last_name can start with any String, and it can also end with any String, but it must contain the value with which the named parameter :keyword will be replaced.
Some examples of using LIKE % expression:
- %:keyword – ends with a value that the named parameter “keyword” holds,
- :keyword% – begins with a value that the named parameter “keyword” holds,
- %:keyword% – contains the value that the named parameter “keyword” holds,
I hope this short tutorial on how to use the LIKE expression in Spring Data JPA Native Queries was helpful to you.
