I am facing a problem with writing a MySQL query to fetch distinct results. Here is the scenario: I have a table named city as shown below. I have around 131k records now. I have to select the distinct cities. I tried to do substring but I don’t know the length for each. Help in this regard is appreciated.
City
33098 Paderborn
Paderborn
Berlin
02826 Görlitz
10829 Berlin
Görlitz

This assumes that the only issue is the sequence of numbers and spaces at the beginning (or end) of the city name.
