I'm trying to query an array of bigint[] using SQLAlchemy 0.8 on a Postgresql database.
My query looks like this: ways_with_node = db.query(Ways).filter(Ways.nodes.contains(array([node1.id], type_=BigInteger))).all() and I'm getting the following exception: cursor.execute(statement, parameters) sqlalchemy.exc.ProgrammingError: (ProgrammingError) operator does not exist: bigint[] @> integer[] LINE 3: WHERE ways.nodes @> ARRAY[ -710] It looks like the array() function isn't changing the type to BigInteger. I've tried CHAR and the second argument remains an integer[] array. The query should end up looking something like this: select * from ways where nodes @> '{-710}'::bigint[] Which successfully executes as plain SQL. I've tried different variations of the query, including: db.query(Ways).filter(Ways.nodes.op('@>')(array([node1.id], type_=BigInteger))).all() but the result is the same exception. Since I have run out of ideas, I was wondering if there is a bug in the array() function or if I'm doing something wrong here. -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
