Blobs on Oracle8i

Posted: 2000/07/06 14:55

I have used OCI blob demo and i have made a very simple program that use OCI components BUT why the demo and my program don't works ?

When i'm posting on the OCIQuery.post or i choose a image and use TBlobField.LoadFromFile ..., a error appear :

You can't affect the blob field because is read only and it require one transaction ?

Hi !

I am sorry, but now BLOB support has a lot of problems. I mean support of TDataSet.Edit / Insert methods. So, it really is not working.

If you want (and know how) you can use TOCIQuery and SQL operators - INSERT/UPDATE/... and explicit transaction management. In that case you can update blobs.
