RE: It took more than an hour to update 10,000 records

Is there a parameter that I can tune in init.ora file to improve this process?

Thanks,
David

Bind variables will not buy you anything. The time taken is mainly dependent on the execution plan and the cardinality of the indexes being used. Also any overhead like updating a column that's part of an index, triggers, referential constraints, etc.

I run it on the server. How do I use bind variables?

Thanks,

>From the look of your sql statements it seems that each
statement will be hard parsed because the values are different. If you will use bind variables you can save a lot of time.

Is the script runs on the server or from another computer? If you run the script from another computer you also have the network time added.
