SQL Duplicates

[Sander Martens]

Hi all,

I'm facing the next problem:

I've got a table like this:

Name Size Total

Martens 200 2
Martens 300 3

What I want is run an SQL script which will give me the following answer:

Martens 200 2
Martens 200 2
Martens 300 3
Martens 300 3
Martens 300 3

It should show the data the number of times of total.

Who can help?

Kind Regards Sander

I don't think you're going to be able to do this just in MySQL. You'll
need to do it in another programming language.

FWIW, I agree with Jerry, I'd handle this in application code, not in SQL.

Thanks for the code.

In the meantime I've managed to do it with some programming code.

Kind Regards Sander
