JPA,JPQL: unexpected token: LEFT near line 1

问题

I want to display all the checklists that are not answered and not answered (response checklists is in the ResponsesCheckLists table) using the following parameters: idequipement and idMission.

@Query("SELECT check,resp,eq FROM Equipements eq INNER JOIN CheckLists check WHERE eq.idEquipements = check.equipements.idEquipements LEFT JOIN ResponsesCheckLists resp ON check.idCheckLists=resp.CheckLts.idCheckLists AND resp.Respmission.idMission = :idmiss WHERE eq.idEquipements = :idEqp ")
    public List<ResponsesCheckLists> ListCheckListsNonRepondu(@Param("idEqp") long idEqp, @Param("idmiss") long idmiss);

After running this query, I displays this error message:

antlr.NoViableAltException: unexpected token: LEFT
------
Caused by: org.hibernate.hql.internal.ast.QuerySyntaxException: unexpected token: LEFT near line 1, column 148 [SELECT check,resp,eq FROM com.SSC.DAO.Entities.Equipements eq INNER JOIN CheckLists check WHERE eq.idEquipements = check.equipements.idEquipements LEFT JOIN ResponsesCheckLists resp ON check.idCheckLists=resp.CheckLts.idCheckLists AND resp.Respmission.idMission = :idmiss WHERE eq.idEquipements = :idEqp ]

Edit1:

@Query("SELECT check,resp,eq FROM Equipements eq INNER JOIN CheckLists check ON eq.idEquipements = check.equipements.idEquipements"
            + " INNER JOIN ResponsesCheckLists resp ON check.idCheckLists=resp.CheckLts.idCheckLists AND resp.Respmission.idMission = :idmiss AND eq.idEquipements = :idEqp ")
    public List<ResponsesCheckLists> ListCheckListsNonRepondu(@Param("idEqp") long idEqp, @Param("idmiss") long idmiss);

Error of Edit1;

How to correct this query?

thank you in advance

回答1:

You have a Spring annotation there (@Query) that specifies a JPQL query. Your JPQL query is supposed to follow the syntax highlighted in this link (and the JPA spec). Sadly you haven't followed that.

SELECT {result} FROM {from} WHERE {where} ...

Any "JOIN" has to go in the FROM clause. You already put one JOIN in the FROM clause, but for reasons only known to you, you decided to put another JOIN in the WHERE clause!! In fact you have 2 WHERE clauses in that crap.

It is impossible to tell you what your query should be because you don't post your entities, so we don't see what relations they have, or even what you are trying to achieve. We can only point out your error
