Re: Calling A Source an an If Statement - Qlik Community

Hi All. I'm hoping someone can assist me. At the top of my data load editor I have sources listed.

SET Source_A = File1.txt

SET Source_B = File2.xlsx

SET Source_C = File3.xlsx

I want to be able to create an IF statement that looks at the sources and then creates a value in a field. For example:

IF(Source_A, 'Lions',
IF(Source_B, 'Tigers',
IF(Source_C, 'Bears'))) AS Oh_My;

Any help will be greatly appreciated.

Source_A etc are variables. You can reference them in a script expression using $() syntax. So your if condition would be like:

If('$(Source_A)' = 'something', 'Lions',...

I suspect what you are wanting to do is test the name of the file you are loading? If so, your test would be:

if (FileName() ='$(Source_A)', 'Lions', ....
