Spring data repository sends null as bytea to PostgreSQL database
Try this.
SELECT *FROM WINE wWHERE ?1 IS NULL OR w.id = CAST(CAST(?1 AS TEXT) AS BIGINT)It satisfies the type checker and should have the same properties as the original query. CAST is not a big performance hit if it happens on a constant value rather than a value from a database row.
You are trying to check whether a Java null is equal to Postgres NULL which I think is not necessary. You can rewrite as following and avoid sending null to the simpleTest function at all.
@Query(value = "SELECT * FROM WINE w WHERE (w.id IS NULL OR w.id = ?1)", nativeQuery = true)Wine simpleTest(Long id);
I had a similar issue in an @Query where a Long was being interpreted by Postgres as a bytea. The solution for me was to unbox the @Param...by passing a long value, Postgres correctly interpreted the value as a bigint
