One of the most resource intensive functions in a chart is the If statement. In a lot of scenarios, what you can do is leverage the combination of Pick and Match to replicate the functionality while i...

There’s nothing worse than waiting for a long reload to find out you made a typo. One thing I have made a habit of is copy and pasting script items: table names, field names, variables, etc̷...

If you are like me, you probably use SubField a lot. I had used it for years before I stumbled across one of its most powerful features in someone else’s code. If you do not provide the position...

Arrays and/or Lists are very common in programming languages. In Qlik scripting there are two ways to go about creating an array of sorts. The first way is storing a list in a variable: SET vCount = '...

I can’t tell you how many times a client has said to leave a field in the data model just in case they want to use it later. Just don’t do it. Take it out now, if they want to use it later...
