I use the BLOB in an Oracle table to store IMG and document files. Now for Postgres(9.4.5), I have two options, i.e., BYTEA or OID.
With consideration of passing the params (SAVING) from the Java side as follows:
DiskFileItemDeepy file = myFile; InputStream is = null; long fileSize = 0; if (file != null && file.getFileSize() > 0){ is = file.getInputStream(); fileSize = file.getFileSize(); call.setBinaryStream(1, (InputStream)is, (long)fileSize);
}
...
call.execute();
//When retrieve the data use:
java.sql.Blob blob = (Blob) resultSet.getBlob(tableColumnName);
For the purpose mentioned above, which Postgres data type is a better candidate for replacement the BLOB, BYTEA or OID?
Thanks
Eugene

My goodness, that's out of date (as you should have guessed from the

has been able to dump large objects just fine since 8.1 or so.
I don't know what else an Oracle user might be expecting that we don't
have, though, so I'm hesitant to change the text.
