I added a VARCHAR2 column to my table and used the key_column to update the
VARCHAR2 column with the length of the long_column. Don't ask why !!!

Subject: Re: Length of LONG datatype - ANSWER
I'll address your second question, because I don't know, offhand, the
answer to the first!
IMO, there's almost no advantage to using LONG. There are many
restrictions on its use (e.g., only one LONG in a table), you can't
apply a function to a LONG column, you can't use it in a set operation,
etc. In addition, Oracle says that the LONG datatype will soon be
phased out.
If you can fit your data into 4000 or fewer characters, use VARCHAR2.
If not, go for CLOB/BLOB, which require a little more overhead, but are
much more useable than LONG.
