I believe you always get an array, even if only 1 thing is returned. If you request more than 1 column from the database you can use a comma separated list of variables.
If you haven't tried a simple test to see what it does, I suggest doing so. Just make a test with a JDBC Config data element, a view results tree listener, a thread group, a JDBC query that sets variables and a debug sampler. The debug sampler is your friend. The two things you want to look at in the results tree after you run your test are the JDBC request results tab and the debug sampler. Verify that your JDBC results did, in fact, retrieve columns from the database. Then look at the debug sampler and see how it created the variables for you to use. -- Bruce Ide flyingrhenqu...@gmail.com
