HQL缺少关键字

Question

我一直在找几个小时，但找不到以下查询中缺少的内容：

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

我收到以下异常：

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

Answer 1

我认为您根据Doc错过了关键字AS：

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