SQL（DQL）：WHERE值IN（数组field1）或field2 =值

Question

I'm using Symfony 2. I have Entity Ent1 with Field1 = ManyToMany(targetEntity=Ent2), and Field2 = OneToOne(targetEntity=Ent2).

ManyToMany involves an intermediate table in DataBase.

My request parameter is an instance of Ent2 (in DQL, which means an Id of Ent2 for SQL) ' myEnt ', I need to select all Ent1 entities having ' myEnt ' IN (Field1 array) OR having Field2 = ' myEnt '.

In pseudo-SQL it would be

SELECT(*) FROM Ent1 
(WHERE Field2='myEnt' OR INNERJOIN(Ent2 ON Ent2 = 'myEnt')

which is not functionnal, of course.

Is it possible? If it is, do someone have the correct logic/syntax to reach that?

Thank you very much.

Answer 1

Leave the join part to select the rows to join on and the where to filter so you may need something like this:

SELECT(*) FROM Ent1 
inner join ent2
on ent1.id = ent2.id 
 WHERE Field2='value' OR  Field2.id = 'value'
