How to write multi column in clause with sqlalchemy

Question

Please suggest is there way to write query multi-column in clause using SQLAlchemy?

Here is example of the actual query:

SELECT  url FROM pages WHERE         


        

Answer 1

Assuming that you have your model defined in Page, here's an example using tuple_:

keys = [
    (2752937066, 'http://members.aye.net/~gharris/blog/'),
    (3799762538, 'http://www.coxandforkum.com/')
]

select([
    Page.url
]).select_from(
    Page
).where(
    tuple_(Page.url_crc, Page.url).in_(keys)
)

Or, using the query API:

session.query(Page.url).filter(tuple_(Page.url_crc, Page.url).in_(keys))
