How Do You Insert Large Blobs Into Oracle 10G Using System.Data.OracleClient?

Question

Trying to insert 315K Gif files into an Oracle 10g database. Everytime I get this error "ora-01460: unimplemented or unreasonable conversion requested" whe I run the stored procedure. It appears that there is a 32K limit if I use a stored procedure. I read online that this does not apply if you are doing a direct insert, but I do not know how to create the insert string for a Byte Array. This is a thick client running on the server so not worried about SQL Injection attacks.

Any help would be greatly appreciated. FYI, code in vb.net.

Thanks,

Dave

Do not use System.Data.OracleClient. It has performance issues with BLOBs/CLOBs. Now it's deprecated by Microsoft and will not be supported. Instead of it, use Oracle's native ODP.NET.
