I have the rule-based labelling provided for my labels, inside which I want to make other distinctions. Unfortunately, the multiple CASE WHEN seem to be not valid, as I get an error:

Parser Errors: syntax error, unexpected STRING syntax error, unexpected END, expecting $end

My code looks like this so far:

"rotate_angle" = 90 THEN
"rotate_angle" = 270 AND "Plan" = E

and I believe the situation is similar to this query:

QGIS Multiple CASE WHEN/THEN Statements for Expression Based Labels

where the rule-based styling was proposed. In my case it has been already applied, but I need a step further - a few rules inside of the given rule. Is it possible?

  • Please provide example data. I suppose the "rotate_angle" = 270 is superfluous, but can't confirm w/o having a look at the data.

You can't have ELSE with a condition. ELSE is used for catch all others values, so it's a syntax error.

And E seems to be a literal value --> missing quote ('E')

  WHEN "rotate_angle" = 90 THEN '10,0'
  WHEN "rotate_angle" = 270 AND "Plan" = 'E' THEN '8,10'

or just

  WHEN "rotate_angle" = 90 THEN '10,0'
  ELSE '8,10'
