Assert Exists By Ids

Definition​

The assertExistsByIds method allows you to confirm that multiple record exists in a table at the same time, filtered by its primary key. If at least one record does not exist, this method throws a KException.

Available methods​

  • assertExistsByIds(List<Y> ids, HttpStatus httpStatus, String message): Receives multiple primary keys value and the HttpStatus and message to throw.
  • assertExistsByIds(List<Y> ids, KAssertExistsFunction<KWhere, KQuery> kAssertExistsFunction, HttpStatus httpStatus, String message): Receives multiple primary keys value, a KAssertExistsFunction that allows adding new conditions to the base query and the HttpStatus and message to throw.
  • assertExistsByIds(String jdbc, List<Y> ids, KAssertExistsFunction<KWhere, KQuery> kAssertExistsFunction, HttpStatus httpStatus, String message): Receives the name of datasource connection to which you need to connect, multiple primary keys value, a KAssertExistsFunction that allows adding new conditions to the base query and the HttpStatus and message to throw.

Example: List<Y>, HttpStatus, String​

Java code:

final List<Long> ids = new ArrayList<>();
ids.add(199L);
ids.add(997L);

languageRepository.assertExistsByIds(
    ids,
    HttpStatus.BAD_REQUEST,
    "At least one language does not exist!"
);

SQL generated:

WITH cte_ (id) AS (
    VALUES (?1), (?2)
)
SELECT
    BOOL_AND(
        EXISTS (
            SELECT ?3
            FROM auth.language la
            WHERE la.id = _🕆_JESUS_SAVES_🕆_.id
        )
    )
FROM cte_ _🕆_JESUS_SAVES_🕆_

Parameters:

  • ?1: 199
  • ?2: 997
  • ?3: 1

Example: List<Y>, KAssertExistsFunction, HttpStatus, String​

languageRepository.assertExistsByIds(
    ids,
    (KWhere kWhere) ->
        kWhere
            .and(LANGUAGE.ACTIVE.isTrue()),
    HttpStatus.BAD_REQUEST,
    "At least one language does not exist!"
);
