I haven't used arrays with postgresql, so I've no idea if this works, but for documentation you probably want to start here: http://docs.sqlalchemy.org/en/latest/core/type_basics.html#sqlalchemy.types.ARRAY According to those docs, if you've declared a table with a column using the ARRAY type, you should be able to query elements of the array using python indexing operators. For example: table = sa.Table('mytable', metadata, sa.Column('array', sa.ARRAY(sa.Integer))) sa.select([table.c.array[1]]) Hope that helps, Simon -- SQLAlchemy - The Python SQL Toolkit and Object Relational Mapper http://www.sqlalchemy.org/ To post example code, please provide an MCVE: Minimal, Complete, and Verifiable Example.
