I'm trying to write an expression which will return a TRUE or 1 type result if the string in "column3" is the same as the string in either "column2" or "column1".
I've tried "column3" IN ("column2","column1") which would seem logically to do the job, but it just returns a blank cell.
I'm using QGIS 2.6, any ideas would be much appreciated.
