Question

I’m very new at SQL scripts and couldn’t figure out how to make a specific for each loop. I need to do something like this:

I have Sites and SiteCrawls tables.

Basically, for every site I need to create a new SiteCrawl and that SiteCrawl‘s Site_ID column will equal to that site’s ID.

How can I do this?

Answer 1

insert SiteCrawl
(
    Site_ID
)
select
 s.Site_ID
from Site as s
where s.Site_ID not in (select Site_ID from SiteCrawl)
