ODBC Error trying to insert PDFs

Hi,

I am trying to insert a PDF into a BLOB column in Oracle using some methodology I found on a previous forum post. Essentially using SQL Parameter Mapping on the binary property after reading the PDF in with Binary Reader component. However, I get the following error:

[22001][DataDirect][ODBC Oracle Wire Protocol driver]String data, right truncated. Error in parameter 1

Can anyone point me in the right direction?

Kind Regards,
Liam
