[postgis-users] How to take sum of varchar column ?

[Taylan Karakurt]

Hello everyone,

I have an example job from my client and figuring out it with postgresql. I
imported the csv data which is approx. 3 million rows. I'm trying to get
for example how many airport id has EGLL code but not with where command.
Tried to sum but didnt work. We were doing same thing before at my previous
job. Every help appreciated.
