I have a shape layer in qgis with blank attribute table. I want to fill attribute table with false data randomly. I successfully update the field with integer values using 'rand' expression. I am stuck at 'how to randomly fill string values.'
Suppose I have shape with drain 500 features. I want to enter values in drain_name field with values "ravi", "Sangpo","ganga",... etc.
Which expression should i use to update the drain name with random string value.
