I was going to suggest something similar, but there are some issues with this as well.

First, one must make sure to still commit at regular intervals. The original poster mentioned 10M rows (I'm guessing 10 million) - you'd have to have a rather large transaction log if you're going to batch all of these rows in a single transaction.

Second, batching may not necessarily gain you all that much - certainly with Sybase the total amount of work that the database needs to do whether you batch transactions or not is the same - the only real difference is that rows are only committed to the "real" table when the server gets the COMMIT TRAN command instead of placing each row there individually (i.e. the total amount of disk IO is the same).
