QGIS Labeling – Adding Text in Integer Field for Label

Question

I am labeling mile points along several different lines in QGIS 3.2. For the labels I am using a field that is just integers so the labels are 1, 2, 3, etc but I would like to add some text so that that for one line it'd say, for example A1, A2, etc.

Is there a function to add the text characters in either the field/a new field or in the label styling window?

Answer 1

Yes, there is! With string concatenation || you can make label with custom strings, or with values from other fields. In Label with field write expression like this:

'A'||your_field

or use expression builder
