I'm writing a Snowflake dialect for exposed. The good news is that 11/19 tests pass 🙂 If you're interested in this work, my fork and branch https://github.com/dmitchell/Exposed/tree/snowflake. I'd welcome critiques and help. Right now, it's failing on the prepared statements where somehow the values are not properly going to the payload.

btw: re convo in https://github.com/Tapac/exposed-wiki/pull/6#issuecomment-651028163 • I'll check w snowflake re getting a db accessible for exposed testing. I can see a lot of reasons they'd be reluctant (abuse potentials, but) • thanks for the pointer to the methods for indexes. I hadn't found them yet. • the byte issue ends up being a bug in jdbc.snowflake which I've patched but I've also written a guard in exposed to avoid https://github.com/snowflakedb/snowflake-jdbc/pull/271 • thanks for the current timestamp pointer, I'd fixed that but there seems several alt code paths which don't pick it up. I think I've got them.
Can the authorities for exposed sign up for a trial snowflake account https://trial.snowflake.com/ so that the unit tests will work for others (I'm testing against my company's non-public account)
