Postgres DB의 JSONB 열에 대해 JPA로 쿼리를 작성하려고합니다. 쿼리는 거의 Postgres JSON Documentation에서이 예를 다음과 같이 표시됩니다Postgres의 JSONB 열에 대한 JPA 쿼리
-- Find documents in which the key "company" has value "Magnafone"
SELECT jdoc->'guid', jdoc->'name' FROM api WHERE jdoc @> '{"company": "Magnafone"}';
곳 jdoc 테이블 api에서 JSONB의 열입니다.
지금까지이 쿼리를 실행하는 것은 쉽고 문제가되지 않습니다. 그러나 쿼리를 매개 변수화하려고하면 막혔습니다. 때문에,
가1)이 작동하지 않습니다 여기에
내가 시도한 몇 가지 질의입니까? '-signs 사이에 인식되지 않습니다 :String name= "Magnafone";
JPA.em().createNativeQuery("SELECT jdoc FROM api
WHERE jdoc @> '{\"name\": ?}'", Record.class)
.setParameter(1, name)
