I am trying to write an ELSEIF conditional statement in QGIS Field Calculator (version 1.8.0). I have used an example I found online:
CASE WHEN val < 0 THEN 'negative' WHEN val = 0 THEN "neutral' ELSE 'positive' END
I modified the statement as follows:
CASE WHEN "GRID_ID" = 1 THEN 'complete' ELSEIF "GRID_ID" = 2 THEN "in progress' ELSE 'not started' END
This statement would not run, the Output preview stated Expression is invalid. The more info stated: Parser Error: syntax error, unexpected COLUMN_REF, expecting WHEN or ELSE or END
I am wondernig if anyone has had this error, and if they can share what they did to fix it.
