Add the following expressions: The syntax highlight may suggest that these are incorrect they are not Add a listbox for Year. This is proven by the fact that the minus and equal sign are not needed to be written together ‘-=’ is a single operator, where ‘=-‘ are in fact two, the equal sign telling Qlik to make selections and the – sign to select everything except Belgium. Perform the following steps to exclude the values from the results using Set operators: Add a straight table with Country as dimension. This means that however we make selections, we will always see all sales, expect for Belgium. Belgium is excluded.īut what happens with ‘=-‘? In that case we tell Qlik to make selections in the Country field, for everything except Belgium. However in the ‘-=’ set analysis we will only see the 80 of Denmark. We see that the total result should be 180. Referring to the example above we see that Belgium and Denmark are both selection. Therefor it is still possible to make selections, however, Belgium will never show up in the result of the expression. By effect, this will show all possible selections in the country field, except Belgium. This will make Qlik exclude Belgium from your selections. Now let’s place a minus in front of that to make the expression Sum(} Sales). The p () function extracts the possible values based on your filter, in this case, it was Expense and Labor, and operator does the and operation. Whatever other selection you will make, it will still only show the Sales for that condition. For example the expression Sum(} Sales) will select only Belgium in the country field. We should view the ‘=’ sign as an operator which selects or actually replaces current selections. The difference lies in the placement of the ‘-‘ minus sign. Keeping that in mind and lets evaluate what both statements do. As in the question, we tell Qlik to make a selection in the Country field. Based on the values in the set condition, Qlik evaluates this as a selection on chart level. As we all know, set analysis works by sort of making selections within the aggregation itself. The trick in this question is the fact that the end user still wants to make selections. And that is certainly not to our surprise since set analysis is the staple (and maybe the bane) of most Qlik developers. Quite an impressive amount of answers this time around. Last Friday we asked the following Qlik Data Architect certification practice question about excluding values in Set Analysis: Every Friday at Bitmetric we’re posting a new Qlik certification practice question to our LinkedIn company page.
