update long string cell in table by SQL command

725537Jan 23 2011 — edited Jan 23 2011
Hi,
I use sqlplus in oracle (linux).
I have a table and the string cell have long string .
Like below :

column A Column B

A BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB
BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB
.....................................BBBBBBBBBBB


So, I need to edit/update the row A and the value in Column B.
But the string in Column B is so long and I only need to edit one character.
IF I use update command , I need to type very long string and
it is easy to wrong edit .


old value :
BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB
BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB
..................67890..............BBBBBBBBBBB

new value :
BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB
BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB
..................12345..............BBBBBBBBBBB





Any suggestion and other way to ensure the string will not type wrong ???
