Hi all,
I have a varchar2 column with data. I need to update it in the middle. If I issue the followith command:

update table T1
set substr(column1,100,10) = rpad('5',10,' ')

then i am getting an error message: Missing equal sign.
How do i do something like that? Is it possible?
Thanks,

You can create a view based on your SUBSTR() rules and then update the view.

CREATE VIEW my_view as SELECT substr(column1,100,10) "SUBSTR_COLUMN" FROM t1;

UPDATE my_view
SET sybstr_column = RPAD(...);

Hope that helps,
