Hi,
I am trying to get erlydb running outside of erlyweb. So I tried to run the
test/erlydb/erlydb_test.erl program. It's not working, though. I had to
swap around the parameters on the code_gen call. So it obviously hasn't
been run since things changed in 0.7.
After that change, it runs for a while, but fails later on. Something is
going wrong with the code gen, I guess, as the order of the parameters
is not matching up in the generated SQL.

I haven't actually ran this test code in a while so it could be
broken. What DBMS are you using?
Btw, it should be quite easy to use ErlyDB without ErlyWeb. Just call
erlydb:start() followed by erlydb:code_gen().

The same error occurs with both MySQL and PostgreSQL. The error
message that I posted came from MySQL. I plan
to use it with PostgreSQL, though.

I am just getting started, so I figured I would start by running the
tests.
Is there a complete example somewhere that I could start with
instead?
