Hi ,

I have an application written in C++ which uses OraOLEDB provider…Earlier
I used OraOLEDB.Oracle 8.1.6 and it works fine…

But now I upgraded to OraOLEDB.Oracle 8.1.7.3…. and the problem
starts…Now I am not able to view data in fields of type BLOB/LONG….BOB
fields returns value NULL….but Value is there in the field…I am able to
insert data to blob field using my application..

My question is : Is there any special seting for OraOLEDB.Oracle 8.1.7 to
retrieve data from a BLOB field other than settings for OraOLEDB 8.1.6

If anyone knows any solution, please post it...
Thanks,

Regards

Hi all,

I got the problem..In my code for blob foields I set dbbinding.cbMaxLen = 0 ...But from 8.1.7.x onwards we have to provide a non-zeo value to cbmaxlen.

So I put dbbinding.cbMaxLen = sizeof(IUnknown *)..

It works perfectly fine...

Thanks
