Table definition
*from sqlalchemy import *
testa = Table(
"testa",
metadata,
Column("id", BigInteger, primary_key=True),
Column("str_var_a", String, nullable=True),
Colmn("bool_var_a", Boolean, nullable=True),
)
*
and I need to execute a query like.
*select([testa.c.id & 15])*
But while executing this query getting an error

But in Postgres using psql command I can perform the query *SELECT id & 15
FROM testa;*. Is there any *support* for this in *sqlalchemy*.
