HQL 缺少关键字

Question

I've been looking for hours but can't find what is missing in the following query:

SELECT count(*) FROM Request r JOIN r.status status WHERE r.uniqueId = '123456'

I get the following exception:

java.sql.SQLSyntaxErrorException: ORA-00905: missing keyword

Answer 1

I think you missed the keyword AS according to Doc :

SELECT count(*) 
FROM Request r INNER JOIN 
     r.status AS status -- AS missed
WHERE r.uniqueId = '123456'
