users On PostgreSQL, if only one key or index is used, the SQL operator -> is used. If multiple operators are used then the #> operator is used. SQLite users On SQLite, "true", "false", and "null" string Q(question__startswith="What") Q objects can be combined using the &, |, and ^ operators. When an operator is used on two Q objects, it yields a new Q object. For example, this statement yields a single &, |, and ^ operators and use parenthetical grouping. Also, Q objects can be negated using the ~ operator, allowing for combined lookups that combine both a normal query and a negated (NOT) query: Q(q
