title: Non-standard joins in QlikView?
body: <p>Lately we have been testing QlikView in the office. The first impression is good: it has an attractive interface and performs very fast. We want to use it as a database frontend for our customers. We are also trying to determine whether it can take over parts of our relational database structure. However, we are in doubt whether its database functions are advanced enough to be more than an attractive frontend.</p>
  
  <p>Specifically, we run into the following problem. The equivalent of normal JOIN (equijoin) operations can be done in QlikView simply by setting equal field names across tables - those fields will then be linked. However, one of our traditional SQL JOIN operations uses a "BETWEEN" query to find out whether a date is in a certain range and join the data on that. </p>
  
  <p>Is it possible to specify such a "non-equijoin" relationship between tables in QlikView? Or is this an inherent limitation to the so-called "associative database" structure? </p>
