ODBC Driver and Connection Information

ODBC Driver and Connection Information

ODBC Driver and Connection Information

(OP)
Everyone,

Recently, I had to research a problem I was having switching my ODBC connection from an v8.0 Postgres database to v8.1.  

Below is a list of psqlODBC drivers, versions, dates, and results of my research.

------------------------------------------------------
PostgreSQL Win32Clients    8.00.00.04  1-17-2005     CX=1b8143a9
(OLEDB/ODBC)       
------------------------------------------------------
Performance -> Good Performance          
Unicode ->     Error! Does not Connect to v8.1 UTF8, but ok with 8.0 'Unicode' type

------------------------------------------------------
PostgreSQL        8.00.01.02  8-2-2005    CX=1b103a9    
------------------------------------------------------
Performance -> Good Performance          
Unicode ->     Error! Does not Connect to v8.1 UTF8, but ok with 8.0 'Unicode' type

------------------------------------------------------
PostgreSQL         8.00.01.02  8-2-2005    CX=1b8143a9       
------------------------------------------------------
Performance -> Good Performance          
Unicode ->     Error! Does not Connect to v8.1 UTF8, but ok with 8.0 'Unicode' type

------------------------------------------------------
PostgreSQL (2drivers)    8.01.02.00  1-31-2006    CX=1b8143a9     
(bunded with ANSI and UNICODE specific drivers)
------------------------------------------------------
Performance -> Good Performance
Unicode -> Works with UTF8, but requires the selection of the "PostgreSQL Unicode" Driver.  This is for both 8.0 and 8.1 versions of Postgres

Hope this helps your ODBC endeavors a bit.  The CX is the last part of the connection string specifying parameters for connecting to the database.   Declare/Prefetch was selected for the above tests.

One of the Connection String Used for my DSNless connections...

ODBC;DSN=PostgreSQL Unicode;DATABASE=mydatabase;
SERVER=172.10.10.10;
PORT=5432;
A6=;A7=100;A8=4096;B0=254;B1=8190;BI=0;C2=dd_;;CX=1b8143a9
