To do that you have to number the rows you're inserting, and add an offset to make them begin at the largest number in the table. You could do this by <a href="/blog/2005/09/27/simulating-the-sql-row_number-function/" rel="nofollow">simulating the ROW_NUMBER function</a>, but it would be ugly at best.</p> Not that I can think of right away.

For instance "insert into t1log" with a select statement that returns several rows instead of one as in your example above?</p> Is there a way to insert several rows at once and have the counter increment by one for each row?
