Summary: UUID not being returned correctly

Initial Comment:

I have the following in a postgres 8.3 DB:

Create Table test(f uuid);
insert into test values('e964684f-87fe-49d9-9b87-137cc83165ea');

I have the following VB.Net 2005 code that connects to this DB (using either ANSI or UNICODE driver); full connection string below. I use a DataAdapter as follows:

  Dim c As New ODBC.ODBCConnection(My.Settings.ConnectionString)
  Dim DA As New Odbc.OdbcDataAdapter("select f::text, f from test", c)
  Dim Tbl As New DataTable

When I inspect the values, they differ:


The original can be stored using the ODBC driver, it just seems to have trouble retrieving it.

Full connection string:

Driver={PostgreSQL ANSI};database=time_log;server=xxx.yyy.zzz.ttt;port=5433;uid=root;sslmode=allow;readonly=0;protocol=7.4-1;fakeoidindex=0;showoidcolumn=0;rowversioning=0;showsystemtables=0;fetch=100;socket=4096;unknownsizes=0;maxvarcharsize=255;maxlongvarcharsize=8190;debug=0;commlog=0;optimizer=0;ksqo=1;usedeclarefetch=0;textaslongvarchar=1;unknownsaslongvarchar=0;boolsaschar=0;parse=0;cancelasfreestmt=0;extrasystableprefixes=dd_;lfconversion=1;updatablecursors=0;disallowpremature=0;trueisminus1=1;bi=0;byteaaslongvarbinary=0;useserversideprepare=0;lowercaseidentifier=0;xaopt=1

Hi Nicolas,

I cannot reproduce the case with MS Access 2002.
Could you attach the Mylog output of your case?

Done the same on a x86 32 bits host / Access / ODBC driver

Same results, GUID are not well transfered.

Same bug here with the x64 latest driver version (2011-12-30 version)

Context :
- From MS Access 2010 64 bits
- Replication number field GUID
- Export table to ODBC tool

With the unicode driver the tables are created correctly i-e fields are mapped to uuid fields (with ansi version they are mapped to bytea fields) but data in them is not ok.

Source is GUID like : {7AB02082-2242-4A65-A7E3-6B624BF4873E}

Transfered data is like :  00410037-0042-0030-3200-300038003200

Thanks for the quick response!

I tried the ASCII driver, and it worked, which is great!

How stable are the beta drivers? and/or any schedule for
releasing a production version?

Thanks again.

Could you try the drivers on testing for 8.3.0300 dll at
