Yeah, that’s what I thought. Trying to avoid proliferation of libraries (and digging into the main app’s source) at the moment so was seeing if I could use JMeter to extract the data…It would work if JMeter had an ‘ignore header row’ option on it’s CSV Data Set.

This example returns a single row resultset each time the JDBC Request is executed.

If you wanted to iterate, the query can be parametized using standard JMeter variables.

If you just wanted to populate a single large (multi-row) dataset then I would just use a CSV Data Set Config and populate that as part of your pre-test build e.g. via ant or the command line.

Really just depends on how you intend on using the data i.e. static data, transactional data etc

Still learning how to use JMeter, I don’t quite understand how this example might work if I have a large dataset and want each iteration to use a different value. But then, there are lots of things I still don’t understand about JMeter…
