DELETE FROM users WHERE id=?
As for more than one row, databases start to digress. Some give you the option to use IN(1,2,3)... but personally, I'd just delete them one by one in a loop. It's not like that would take such a long time: typically a small query will execute in a few milliseconds.
As you didn't say what kind of interface you're using, I can't go into much more details. In a HTML form you typically use the same name for every checkbox, and the id as the value. Then, for every checked checkbox, you'll get a parameter checkboxname=rowid. It's easy to loop through those. | [reply]

- Get the values of the checked checkboxes (How you do that depends on what type of checkboxes they are. Tk? HTML via CGI? You didn't say.)
- Prepare an SQL statement that deletes one entry (determined by a bind variable). (Assuming you are using an SQL database, you didn't say.).
- Loop over the values you have, executing the SQL query (with the current value) each time.

Or use one of the HTML::DBForm variants (as far as I can see HTML::DBForm doesn't do checkboxes, only radio buttons, tables or dropdown lists), which can provide this for you.

Hi,
you can get the list of users from the DB.
Display the users and make sure that your checkbox value should identify the user_id ( may be whatever u can identify your user as unique ).When multiple users are selected,then in the CGI you can get it (user ids )in the array-context .If your db supports sub-query then, you just do,
delete from tbl_name where id in (join(',',@usr_id_array));
Oterwise, you just prepare a delete query (outside the loop )and execute the query in the for loop for each user id.
This will delete all the users from the db.
