To avoid painful quoting the mysql reference manual suggest binding
the value like this:
$sth = $dbh-prepare (select name from toolbox where name LIKE

That has issues similar to REGEXP, because the value can contain
LIKE-wildcards such as %

Are you using do() instead of prepare()? Placeholders go into with
prepared statements, not immediate executions.
See the DBI documentation:

In your code there is:

Is there a simple way to create a new table with the same structure

That instruction doesn't guarantee that the new table has the same

The tranid and certno in your where don't have table

more.
I didn't know that dropping the table ids could make a difference.
I'll try adding them. Thanks.

Huh? It is fine if you can deliberately turn it off, but by default such

I searched all night and cannot find an example of how to do this

This should do it:
