So my problem is all values are NULL if I join my CSV table to a point shapefile, why? (QGIS)

I tried so many things but I cannot find and handle the problem. I have customer names in the CSV, account numbers as well, digits and letters.

OK, I put a screenshot here, that is maybe better to see what I mean.

  • Do both your csv file and your point shapefile have a common attribute that you are joining? – Joseph May 28 '15 at 15:27
  • yes it looks like this 'D00 045' in both columns. this are account numbers – Juli May 28 '15 at 15:39
  • Or is there somebody who knows which kombination can I use in the field-calculator to delete the space in the number like this 'D00 0054' ??? that would be also interesting – Juli May 28 '15 at 15:54
  • Could you also include the exact steps that you used to do the joins? – Aaron May 28 '15 at 16:26

So now I got it. I tried something else. I wanted to remove the space out of the numbers which are these ID to join the csv.

I could delete the space with the field-calculator, the funnction for that is replace("text",' ','') so and then the space was deleted. then I joined the csv and dadada it works. the values are all there, not NULL anymore.

Thank you very much all of you for your help!!!keep it up
