Hi,
I just installed the latest snapshot on my PC where I have my Access test databases and now when I do a linked table I don't get anything back without a searchpath.
before I would at least get public.

Thanks,

Re: [ODBC] Schema support






Hi Dave,

I just started using the PG odbc driver with access and I noticed that the only schema that would show up was public, even though I had added several of my own that are visible.

The only way I could get it to work was with the searchpath, and that does not seem to me how it should work.

The search path is a marginal solution because if you add new schemas you have to update every single DSN with the new search path, this can be alleviated some by using a file DSN but it is still a huge PITA.

I was using the stable version from Nov 2003


Thanks,

[ODBC] Schema support







There have been a couple of reports that psqlODBC does not support
schemas. This is not strictly true, it actually has full support for
schemas, however, SQLTables honours the search_path variable on the
server and hides objects in schemas that are not visible.

I'm not convinced this is the correct behaviour - SQLTables should show
everything afaict, unless a parameter is passed to it to filter the
output. The micro-patch below corrects this - however I'm not 100% sure
there won't be any side effects I haven't thought of. I'd appreciate it
if I could get some feedback.

Thanks Dave.
