How can I make each row in the resultset returns multiple times?

Question

I'm writing an application that uses Mysql and for now my tables don't have many data in it. I want to test how my application handles a larger amount of data. In order to do that I need each row in the resultset to repeat itself several times.

I know that I can run the query and UNION it with the same query and UNION that with the same query. Is there a different way that makes it easier for me to choose how many duplications will occur?

Answer 1

Make sure you have a table to insert into

To generate dummy data. http://www.generatedata.com This will generate the data as well as the insert scripts.

Then Just create a massive dataset

你可以自己进行交叉连接，这会产生2 ^ n的结果，但这一切都将是肮脏的黑客
