A very elegant link table script

Some nice out of the box thinkingToday was the last day of the Masters Summit for Qlik in Johannesburg and we all had a great time. One of the things I very much enjoy about these events is the chance to speak with so many experienced people who are enthusiastic about Qlik and keen to share their knowledge. I always go home with some cool new tricks and insights.

What I want to share with you today is an alternative script for building a link table. This was shared with me by Rene McGregor and the nice folks over at QlikView South Africa (who have also been very supportive in bringing the Masters Summit to South Africa, much appreciated).

Masters Summit for QlikView; London and BarcelonaComing to London from October 9  to 11 and to Barcelona from 14 to 16 October, the Masters Summit brings you 3 days of hands on sessions where we will discuss advanced techniques in building complex solutions with QlikView. The goal of this event is to take your QlikView skills to the next level and help you become a QlikView  master.

For the early birds, there is an attractive discount of US$ 300 (around 225 Euro’s) until August 16th, which, for example, should be enough to cover air fare from most locations within Europe. Make sure you do not miss out on this great offer and:

DISTINCT can be deceiving

DISTINCT can be deceiving

Never think you know it all! Today I have for you a little ‘gotcha!’ about the LOAD DISTINCT statement that I picked up from Oleg Troyansky at the Masters Summit for QlikView.

Common knowledge about LOAD DISTINCT is that it will remove duplicate records from the input table, similar to how the DISTINCT clause works in SQL. For example:

Regular LOAD DISTINCT

However, when used in combination with the JOIN or CONCATENATE statement, the results can be surprising, and even counterintuitive.
