Hi,
I am developing a web app using SQLite (which I will switch to
PostgreSQL in production) and came across a weird select error when
using schema. The attached file test.py reproduces the error and
output.txt is the output from running the script.
I have tested with 0.4.2p3 and trunk r4097.
Am I missing something?
Cheers,
Nick
