Re: [sqlalchemy] SqlAlchemy dynamic query generation
Hi, Try composing a criteria using and_(), or_(), or its equivalent binary operators ,|: crit = literal(false) crit |= (table.c.field == value) crit = (table.c.field == value) etc... And then: q = session.query(entity).filter(crit) 2011/12/22 Sana klh sana.kl...@gmail.com I tried it but i still get the same error.

Re: [sqlalchemy] SqlAlchemy dynamic query generation
the string you are generating must be proper sql. to test is you migth print it and try in directly against the db. but what you show us is for sure no valid sql.
