Hello,
I am trying to bind a list for an in() operator in a pure SQL query :
import sqlalchemy
engine = create_engine('mysql://localhost/database')
connection = engine.connect()
connection.execute(engine.text(select * from user where email in
(:emails)), emails=['ta...@ziade.org'])
This will fail because the dialect will not bind a list for the
:emails params.
Is there a way to do this ? I looked at the expression compiler but
didn't find anything relevant.
Or do I have to build the query manually with a ','.join() in this case ?
you do. bind parameters don't expand into arrays with relational
databases.
Options to get around this include, putting a subquery into your in(), or
of course SQLA's in_() operator generates the bind parameters for you.

Tarek
