JMETER + query regarding Mysql database

Question

I am using wordpress application and running Jmeter to perform load test on "wordpress" app. When I am creating a blog, I capture through JMETER via proxy and 1 blog is created, with a new record in mysql database say id is 2.

When I run again the same suite of jmeter, I get the results but new records are not added to mysql still the same id 2 is used.

If I say no of threads as 2 and loop count as 1, will 2 new records be added to MYSQL?
I don't see this happening.
Just need some clarification on this.

Answer 1

yes 2 records should be created. Once you record, you need to variabilize what is dynamic before replaying, to do that you typically use Regular Expression Extractor to extract the id for example and can then use it with ${}
