how works ExecuteOracleNonQuery ?

ExecuteOracleNonQuery comes back the rowid of an INSERT
in it's out parameter.

I don't know why, but the result is supposed to be base64
encoded. But I'm starting to be sceptical.

for instance a line like:

byte[] b = Convert.FromBase64String(rowid.Value)

raises an exception saying the length of rowid does not
match.

Has anybody been successfull in using
executeOracleNonQuery .
How did you do that?

thank you
