[sqlalchemy] Re: Dialect for Vertica db connectivity ?

2013-04-01 Thread James Casbon
I put a rework of the code posted by Bo into a package https://pypi.python.org/pypi/vertica-sqlalchemy/0.1 Selects, joins, table introspection works. Let me know if you can use it. Does anyone have an email for Bo so I can attribute him and check the license? thanks, James On Saturday, 16

[sqlalchemy] mysql + query.execute memory usage

2009-11-18 Thread James Casbon

Ah, thanks. Should have searched the bug reports as well as the list. On Jun 12, 3:27 pm, Michael Bayer [EMAIL PROTECTED] wrote: this is ticket #1074.   A slightly klunky workaround for now is: col = t1.c.c1.in_([select([t1.c.c1]).as_scalar()]) On Jun 12, 2008, at 10:04 AM, casbon wrote
