Now just call this method like Pageable topTwenty = PageRequest. Amazing, right? Read this documentation for better understanding. If you dont know already, Spring Data JPA constructs Query from the method names. You can do it by proper method naming List String userId, Pageable pageable) = true, value = "SELECT * FROM SLSNotification s WHERE s.userId = :userId ORDER BY snumber DESC LIMIT 20")Īdditionally if you want to exploit the handy features from Spring Data JPA, And have nativeQuery = true in annotation to set JPA provider(like Hibernate) to consider this as a native SQL query. MySQL can apply a number of query optimizations when this clause is present in the SQL. You can provide limitations by limitstatement in your SQL. In MySQL, if we want to extract a subset of rows from a larger possible result-set, we can use LIMIT and OFFSET: LIMIT R - Used to constrain the number of rows ( R) returned by the SELECT statement. How can I call entity manager or something or anything to do this ? I want my List String userId) method to retrieve a limited set of data. List String a from SLSNotification a where a.slsNo = :slsNo") List String a.snumber, a.date, a.slsNo, a.slsiUnit, a.productDesc, a.status from SLSNotification a where a.userId = :userId ORDER BY snumber desc") List List a from SLSNotification a where a.userId = :userId") If LIMIT clause is specified in your SQL statement, that places a limit on the number of rows that can be updated. Public interface SLSNotificationRepository extends CrudRepository save(SLSNotification findOne(Integer delete(Integer delete(SLSNotification delete(Iterable a from SLSNotification a where a.slsiUnit in :unitList order by snumber desc") This is my repository package lk.slsi.repository I want to filter first 20 rows from my table I want to filter my records those are retrieved from my custom query provided in annotation. To do this in MySQL, you use the LIMIT keyword and after this keyword you put in the number of rows you want returned based on the query. I am retrieving data by CrudRepository in Spring Data JPA.
