问题
I am trying to allow users to choose a file from local hard disk and to insert it with java in a Oracle Data base as BLOB value.
The setBinaryStream did not allow big files.
with the setBlob I have no way to convert the file to a blob.
Is the import of a blob file from the DB then overwrite it the unique solution?.
Regards, Haythem
回答1:
This is a suggestion that I've used before
In essence a file is an array of bytes, what you can do is to read the file data and use PreparedStatement.setBytes(index, byte[]) to store the data.
Hope this helps.

You need to read the file as any byte array. This byte array can be assigned to Oracle BLOB column.
