Question

ODBC not working (any ideas??)

Asked by: Intern

I am working in VC6 and trying to connect to an Oracle DB in my C++ program.  The problem is that I can't even get the OBDC driver to work in anything.  I have 2.53 driver for Oracle which is quite new.  But anytime I try to connect, even to link tables in Access, I get the following error:

ODBC--call failed.

[Microsoft]..blahblah.. Driver's SQLSetConnectATTR failed

Anyone have any idea what might be causing this?

Probably a silly question but I assume you can connect to Oracle with other tools (SQL*Plus for example) on the PC you are trying it with.

 

by: InternPosted on 2003-07-15 at 09:54:10ID: 8927131

I can connect just fine using SQL Plus and other tools.  I can also connect to the Oracle Database using the following dirvier:

Oracle ODBC driver   Version(8.01.07)

but not with

Microsoft ODBC for Oracle   Version (2.573)


The reason I can not use the first one is that for some reason the Class Wizard in Visual C++ does not work correctly with the Oracle Driver.  It did work with the Microsoft driver, but now I can't connect at all.  I just downloaded the 2.573 driver and replaced the slightly older one that I did have and it still does not work.

 

by: InternPosted on 2003-07-15 at 09:54:45ID: 8927137

dirvier = driver

 

by: m1lPosted on 2003-07-15 at 10:01:48ID: 8927172

Not to take all the credit ! but I had a quick look on the net and it says that it's possible to get this error with a non Oracle ODBC driver but it's non fatal (just a warning), so if you ignore it, maybe you can still get to the DB.

Well the one that I get will not allow me to ignore it, it just lets me hit OK.  Right now I am trying to test my DSN by going into Access and linking external tables to the Oracle DB.  It gives me the error when I do that.  

The Oracle ODBC Driver works for this purpose though.

Hi!

Why dont you try using driver with .UDL file mapping? I used .UDL file to connect to oracle through ASP. If you dont know what I am talking about then simple create a file with .UDL extension and open it. UDL stands for Data Link and work with other vendor provider databases using any of the Drivers installed onto the system.

Stupid question: Why don't u use Oracle Objects for Ole instead of ODBC ?

 

by: InternPosted on 2003-07-16 at 07:30:11ID: 8934733

>>Stupid question: Why don't u use Oracle Objects for Ole instead of ODBC ?

Because I am only a college student and I am stumbling through this any way I can.  I will look into it though.  Do you have a informative web site I could go to?

>>Why dont you try using driver with .UDL file mapping?

I will look into this also.

Thank You for the responses.
