Hi Experts, I'm building a sample beginner project with assistance from a book Ray Paseur recommended and I've got a question I'm not finding the answer to. I'm wondering if it's possible to perform an INSERT query of two rows based on form data collected from a user if the user types in "2" in a "quantity" field. In context, the form collects data on items that the user wants to donate for disaster-relief. In the pre-populated list of items needed, if the user chooses to donate 2 sleeping bags, is it possible to insert those 2 items as separate objects so the db will auto-increment the ID field?  I hope that makes sense...thanks for your input!

Yes, the format is:

INSERT INTO yourtable (field1, field2, field3) VALUES ('x','y','z'), ('x','y','z');

If your last auto increment was at say 100 then rows with index 101 and 102 would be created.

Cobol, if I may, I have a follow up question. In the example above, I mentioned that the number of rows to insert was dependent on the number the user typed in to the "quantity" field. Thus, it will be different for each form submitted. Wouldn't I need a foreach loop or something that would dynamically decide how to handle the number of inserts? Thanks again, I'm doing my best to read and understand but expert help is always easier to put in context and I greatly appreciate it.

Yeah a loop to generate the query works

Just begin the query string ahead of the loop and then concatenate the value strings in the loop and When you come out of the loop you can execute the query.  However you only have a single value so a for loop makes more sense than foreach.
