This is used to produce ARRAY literals in SQL expressions, e.g.:: from sqlalchemy.dialects.postgresql import array from sqlalchemy.dialects import postgresql from sqlalchemy import select, func stmt = select([ array([1,2]) + array([3,4,5]) ]) print(stmt.compile(dialect=postgresql.dialect())) Produces the SQL:: SELECT ARRAY[%(param_1)s, %(param_2)s] || ARRAY[%(param_3)s, %(param_4)s, %(param_5)s]) AS anon_1 An instance of :class:`.array` will always have the datatype :class:`_types.ARRAY`. The "inner" type of the array is inferred from the values present, unless the ``type_`` keyword argument is passed:: array(['foo', 'bar'], type_=CHAR) Multidimensional arrays are produced by nesting :class:`.array` constructs. The dimensionality of the final :class:`_types.ARRAY` type is calculated by recursively adding the dimensions of the inner :class:`_types.ARRAY` type:: stmt = select([ array([ array([1, 2]), array([3, 4]), array([column('q'), column('x')]) ]) ]) print(stmt.compile(dialect=postgresql.dialect())) Produces:: SELECT ARRAY[ARRAY[%(param_1)s, %(param_2)s], ARRAY[%(param_3)s, %(param_4)s], ARRAY[q, x]] AS anon_1 .. versionadded:: 1.3.6 added support for multidimensional array literals .. seealso:: :class:`_postgresql.ARRAY` c (tt|j|i|t|jt r=t |jj|jj|jjdznd|_dSt |j|_dS)N) dimensions)superr__init__ isinstancetypeARRAY item_typer)selfclauseskw __class__s rrzarray.__init__cs#eT#W3333 di ' ' ) #9'3 9/!33 DIIIdi((DIIIrFNc|stjurtjd|jdSt fd|DS)NT)_compared_to_operatortype__compared_to_typeuniquecBg|]}|dS)T)_assume_scalarr') _bind_param).0or r!r's r z%array._bind_param..|sI$$ !D%r)rgetitemr BindParameterrr)r!r objr+r's`` `rr,zarray._bind_paramos  X):::+&."&)  !  rcx|tjtjtjfvrt j|S|SN)rany_opall_opr0rGrouping)r!againsts r self_groupzarray.self_groups3 y')99;LM M M&t,, ,Kr)FNr4) __name__ __module__ __qualname____doc____visit_name__rr,r9 __classcell__)r$s@rrr,sr11fN ) ) ) ) )*rrz@>) precedencez<@z&&ceZdZdZGddejjZeZ ddZe dZ e dZ d Z d Z ejd Zejd Zd ZdZdZdS)raPostgreSQL ARRAY type. .. versionchanged:: 1.1 The :class:`_postgresql.ARRAY` type is now a subclass of the core :class:`_types.ARRAY` type. The :class:`_postgresql.ARRAY` type is constructed in the same way as the core :class:`_types.ARRAY` type; a member type is required, and a number of dimensions is recommended if the type is to be used for more than one dimension:: from sqlalchemy.dialects import postgresql mytable = Table("mytable", metadata, Column("data", postgresql.ARRAY(Integer, dimensions=2)) ) The :class:`_postgresql.ARRAY` type provides all operations defined on the core :class:`_types.ARRAY` type, including support for "dimensions", indexed access, and simple matching such as :meth:`.types.ARRAY.Comparator.any` and :meth:`.types.ARRAY.Comparator.all`. :class:`_postgresql.ARRAY` class also provides PostgreSQL-specific methods for containment operations, including :meth:`.postgresql.ARRAY.Comparator.contains` :meth:`.postgresql.ARRAY.Comparator.contained_by`, and :meth:`.postgresql.ARRAY.Comparator.overlap`, e.g.:: mytable.c.data.contains([1, 2]) The :class:`_postgresql.ARRAY` type may not be supported on all PostgreSQL DBAPIs; it is currently known to work on psycopg2 only. Additionally, the :class:`_postgresql.ARRAY` type does not work directly in conjunction with the :class:`.ENUM` type. For a workaround, see the special type at :ref:`postgresql_array_of_enum`. .. seealso:: :class:`_types.ARRAY` - base array type :class:`_postgresql.array` - produces a literal array value. c$eZdZdZdZdZdZdS)ARRAY.Comparatora*Define comparison operations for :class:`_types.ARRAY`.
