I have a SQL Query:
SELECT documents.*, t_rights.rights, documents_list.docs
FROM documents
INNER JOIN t_rights on t_rights.num=documents.type_right
INNER JOIN documents_list on documents_list.num=documents.document1
WHERE code_document=1 or code_document=1
In case if i have fields documents.document1 and documents.document1 with some value all works fine. But if this field empty i get empty query result.
Its possible make query like this with empty fields?
