    i am trying to upload files to database. I am successfull in uploading documents, txt files, pdf files which are very small in size say 25 kb. But, whenever i try uploading bigger files, i get a error "ORA-01460: unimplemented or unreasonable conversion requested ". Between, i use a stored  procedure to upload file, where in blob datatype is used for file content in oracle. Feels like i am out of path somewhere, Please help.

                    oracleCon = DLORACLEConnectionObject();

    There is actually a number of reasons why you are experiencing this problem... some as obscure as "trying to load Cyrillic data with CL8WMWIN1251 as the NLS_LANG into a database set up as UTF8 language code" while other problems are as simple as loading data through a stored procedure is limited to the PLSQL limitation of 32KB for the size of data coming in as a parameter.  I'm guessing the latter might be your problem... [;)]

    However, depending on how you are accessing the database (not sure since you are using your own(?) Oracle connection object), you may have other options available... try this page: (http://www.oracle.com/technology/oramag/oracle/05-nov/o65odpnet.html) but this would require using Oracle's ODP.NET adapter.


    Hope this helps!
