How to get everything in a string up to the 2nd or 3rd comma in postgresql?

Question

I already had help here .

But when I tried switching from spaces to commas it didn't work

Basically if I have an address:

FLAT 10, ELGAR HOUSE, CHURCHILL GARDENS, LONDON, SW1V 3BS

I need to cut it and have as output only

FLAT 10, ELGAR HOUSE

How to do it in postgresql?

Answer 1

I guess you could use split_part function to get string before occurrence of 2nd comma

select split_part(address, ',', 1) || ',' || split_part(address, ',', 2)
from your_table
