Has anyone ever figured out a way to commit a certain number of rows in a select statement.
I always thought the general rule is that if you can check a box in ssis, there is equitable functionality in Tsql.
I am having a hard time believing that you can't.

A SELECT statement would have nothing to commit. What are you trying to do?

I guess I was pretty unclear.

I am currently using SSIS data flow task to select and insert rows from one table to another.

There is a check box to commit after a certain number of rows.

I would like to stop using SSIS and do it in tsql.

I was wondering if there is any way to programmatically commit a certain number of rows.

Thanks,

In T-SQL you would use the TOP (N) predicate to do that. In the current versions (2005/2008) you can also use SET ROWCOUNT N, but that will stop working with anything updating tables in the next version.

Keep in mind that by doing that - you need to a. structure your statement to "walk through the table" and b. reissue the command enough times to walk all of the way through the table.

Your lack of planning does not constitute an emergency on my part...unless you're my manager...or a director and above...or a really loud-spoken end-user..All right - what was my emergency again?

Right, search the site a bit for batch large transactions. There are some posts and articles about doing this that will help you write the necessary loops.
