Q:

I am using updateBinaryStream method of resultset to update the BLOB field but it is failing after giving following exception java.sql.SQLException: Internal Error: Unable to construct a Datum from the specified input Can anyone help me in this regard ?
A:
That's because you are using FileInputStream. FileInputStream doesn't implement all methods of java.io.InputStream. Use java.io.File instead.
