Thanks for your help Igor, extremely elegant solution.

MySql and msSql have seek commands to go to a( or return) a specific row in a

Is there a generic SELECT statement that can do this for sqlite or indeed,

Good evening.
Due to many deletions, my database is non sequential anymore.
Is there any way to fetch the very first record in the database and find the
id number? Or for that matter, a function to select the last record?

Currently, I return any needed data like this.
select * from pubs,notes,publishers where pub_title like '%salem%'

and pubs.publisher_id=publishers.publisher_id
And it works except for all fields in the matching tables being returned.
Is there any way using

Thanks, but it didn't work the way I expected it to:)
Now I have my query laid out a lot better and can 'slim' it down from here
SELECT * FROM pubs
INNER JOIN notes

Hello folks, sorry to bother you. You must admit I take 6 months or more to
ask questions:):)
Using the first part of this query works fine to return data by searching
the multiple concatenated columns, very happy with that.
