[Resolved] Comparing JDBC results

Assuming that the requests are called 'First' and 'Second', create a script assertion on the second request, and use this code:

import java.text.SimpleDateFormat

def fmt = new SimpleDateFormat('yyyy-MM-ddHHmmss')
def firstUpdate = context.expand( '${First#ResponseAsXml#//LAST_UPDATE/text()}' )
def secondUpdate = context.expand( '${ResponseAsXml#//LAST_UPDATE/text()}' )

Date firstDate = fmt.parse(firstUpdate)
Date secondDate = fmt.parse(secondUpdate)

assert firstDate < secondDate

This assumes of course that there will always be a 1-second difference in the successive LAST_UPDATE values which seems to be the maximum precision for the field.
