#delete(arel, name = nil, binds = []) ⇒ Object
overridden to support legacy binds.
- #exec_insert(sql, name = nil, binds = NO_BINDS, pk = nil, sequence_name = nil) ⇒ Object
-
#exec_query(sql, name = nil, binds = NO_BINDS, prepare: false) ⇒ Object
It appears that at this point (AR 5.0) "prepare" should only ever be true if prepared statements are enabled.
- #exec_update(sql, name = nil, binds = NO_BINDS) ⇒ Object (also: #exec_delete)
- #execute(sql, name = nil) ⇒ Object
-
#insert(arel, name = nil, pk = nil, id_value = nil, sequence_name = nil, binds = []) ⇒ Object
(also: #create)
overridden to support legacy binds.
-
#select_all(arel, name = nil, binds = NO_BINDS, preparable: nil) ⇒ Object
overridden to support legacy binds.
-
#update(arel, name = nil, binds = []) ⇒ Object
overridden to support legacy binds.
