The following examples should give a hint of how DQL is converted into SQL.
|
|
The classes used in here are the same as in chapter 14.1 (Users and groups are both entities etc).
|
|
|
|
DQL QUERY: FROM Email WHERE Email.address LIKE '%@example%'
|
|
|
|
SQL QUERY: SELECT email.id AS Email__id FROM email WHERE (email.address LIKE '%@example%')
|
|
|
|
DQL QUERY: FROM User(id) WHERE User.Phonenumber.phonenumber LIKE '%123%'
|
|
|
|
SQL QUERY: SELECT entity.id AS entity__id FROM entity LEFT JOIN phonenumber ON entity.id = phonenumber.entity_id WHERE phonenumber.phonenumber LIKE '%123%' AND (entity.type = 0)
|
|
|
|
DQL QUERY: FROM Forum_Board(id).Threads(id).Entries(id)
|
|
|
|
SQL QUERY: SELECT forum_board.id AS forum_board__id, forum_thread.id AS forum_thread__id, forum_entry.id AS forum_entry__id FROM forum_board LEFT JOIN forum_thread ON forum_board.id = forum_thread.board_id LEFT JOIN forum_entry ON forum_thread.id = forum_entry.thread_id
|
|
|
|
DQL QUERY: FROM User(id) WHERE User.Group.name = 'Action Actors'
|
|
|
|
SQL QUERY: SELECT entity.id AS entity__id FROM entity LEFT JOIN groupuser ON entity.id = groupuser.user_id LEFT JOIN entity AS entity2 ON entity2.id = groupuser.group_id WHERE entity2.name = 'Action Actors' AND (entity.type = 0 AND (entity2.type = 1 OR entity2.type IS NULL))
|
|
|
|
DQL QUERY: FROM User(id) WHERE User.Group.Phonenumber.phonenumber LIKE '123 123'
|
|
|
|
SQL QUERY: SELECT entity.id AS entity__id FROM entity LEFT JOIN groupuser ON entity.id = groupuser.user_id LEFT JOIN entity AS entity2 ON entity2.id = groupuser.group_id LEFT JOIN phonenumber ON entity2.id = phonenumber.entity_id WHERE phonenumber.phonenumber LIKE '123 123' AND (entity.type = 0 AND (entity2.type = 1 OR entity2.type IS NULL))
