SQL Split Address Line into Separate Columns












0















Whats the best way to split a comma list column into different columns? I am looking for a simple algorithm, heard it is best to avoid scalar value functions, as they might be slow. Searching into many methods, substring, find, splitstring; we need to run this algorithm across millions of addresses, so looking for best, optimal answer with good coding practice.



create table dbo.AddressTest (AddressLine varchar(255))

insert into dbo.AddressTest (AddressLine)
values ('123 Maple Street, Austin, Texas, 78653, 555-234-4589')

-- may not require substring, just looking for good way
select
substring as AddressStreet -- Expected: 123 Maple Street
substring(...) as City, -- Expected: Austin
substring(...) as State, -- Expected: Texas
substring(...) as ZipCode -- Expected: 78653
substring(...) as PhoneNumber -- Expected: 555-234-4589
from dbo.AddressTest
