Re: Generate update / Insert scripts

Thanks HJR !

    I am sorry I did not mention the oracle version. I cannot use the 'merge' sql command as the two tables may be in different databases (under different versions) . I have a local copy of T1 and T2 in the same database. What I have to do is generate scripts and send it to people who will then run scripts, to update their T2 table.

    I guess a pl/sql prg which goes row by row (and col by col) is the only way which I can generate the script.

Thanks,
Sunil.
