Which part of SQLalchemy's dialect is responsible for pre-processing queries?

246 views Asked by At

Apache Superset has some kind of quirk, where any temporal query is sent with datetimes, even when the respective columns are mere dates.

To work around it, I wanted to add some preprocessing to any passing query, so that datetimes are swapped by dates if the respective columns require it.

Any insight I gained about writing the dialect came by comparing ready-made code, which is often repeatable, as other writers seem to encounter the same problem. I haven't so far found anything tangible to shed light on this particular issue.

Has someone perhaps managed to overcome a similar obstacle, and can point me to the relevant SQLalchemy construct / function that I should implement or add to to allow this preprocessing?
