Subject: strange issue with UUID data types
Date: Wed, 17 Mar 2010 11:29:23 -0500
Message-ID: <ff3fa5e776e6a57b7fd9cefe5aeecda2@intermodalsoftwaresolutions.net> (raw)
I'm running Windows 2008 64 bit server with Postgres 8.4.2 (also have tried
Windows 7 both 32 and 64 bit). The origin database is SQL Anywhere 10.
I've got several tables that have a UUID data type with
isscontrib.uuid_generate_v4() as the default value.
All of the tables where these are the primary key work just fine and
properly create the UUID columns.
I also have several child tables that call into the parent table to return
the parent tables UUID. All of the child tables column which I'm returning
the parent tables UUID are defined as UUID data types and no default value.
On all of my machines the UUID returned from the parent tables is always 16
bytes, in fact the numbers are not truncated they don't make any sense or
pattern.
Now I would think that this could be a problem with my program not having
the proper length to hold the temporary data but I've also run this on 2
other machines, one through teamviewer to Windows 2008 standard server with
Postgres 8.4.2 loaded and it's schema's loaded from a pgdumpall.
They are also running the same SQL Anywhere version 10 that we're converting
the data from. When we run the same code on that machine it runs properly
and the UUID returned is correct. I've tried this on his remote server and
it works.
Is there something I'm missing here? Is there somekind of environmental
parameter that I need to set? We've been scratching our heads over this for
about 10 days now trying to figure out why it works in one location and not
others.
Best Regards
