It seems unlikely that's the actual statement: for one, the filter condition seems wrong, because it does not reference the correct column but the whole table. Also, I'd try to find a better way to pass the parameter, possibly without transforming it into a string with isoformat(). ciao, lele. -- nickname: Lele Gaifax | Quando vivrò di quello che ho pensato ieri real: Emanuele Gaifas | comincerò ad aver paura di chi mi copia. l...@metapensiero.it | -- Fortunato Depero, 1929. -- SQLAlchemy - The Python SQL Toolkit and Object Relational Mapper http://www.sqlalchemy.org/ To post example code, please provide an MCVE: Minimal, Complete, and Verifiable Example.
