JMETER + query regarding Mysql database -

i using wordpress application , running jmeter perform load test on "wordpress" app. when creating blog, capture through jmeter via proxy , 1 blog created, new record in mysql database id 2.

when run again same suite of jmeter, results new records not added mysql still same id 2 used.

if no of threads 2 , loop count 1, 2 new records added mysql?
don't see happening.
need clarification on this.

yes 2 records should created. once record, need variabilize dynamic before replaying, typically use regular expression extractor extract id example , can use ${}
