“Invalid PathExpression. Must be a StateFieldPathExpression” in query builder with non related entities

Question

I have four entities: OfficialDocument, Media, NMediaStatus and NMediaType. I\'m trying to translate this SQL:

Answer 1

I answer myself since I found how to fix it:

$qb->select('IDENTITY(od.media)', 'IDENTITY(od.type) AS doc_type', 'IDENTITY(od.status) AS doc_status', 'md.url', 'nms.name', 'nmt.name');

Since od.media, od.type, od.status are composite keys then I need to add IDENTITY in order to make the query work and fix the issue

Answer 2

Simply you can use () where composite keys exist.

$qb->select('(od.media)', '(od.type) AS doc_type', '(od.status) AS doc_status', 'md.url', 'nms.name', 'nmt.name');
