Extract substring address SQL

Question

I have a table with column Address which is like city. City_Name, citysector. CitySector, Street. Street_Name, StreetNumber. Street_Number city. City_Name, citysector. CitySector, Street. Street_Name, StreetNumber. Street_Number

EXAMPLE
Address
c. Paris, s. ParisDowntown, str. Rue Étienne Marcel, nr. 50

How can I substract 4 different columns like city, sector, street, streetNumber from Address column? Thanks in advance!

Answer 1

With a couple of replaces you can change your string format to json, and then use openjson to extract the values.

First, create and populate sample table ( Please save us this step in your future questions):

DECLARE @T AS TABLE
(
    [Address] nvarchar(200)
);

INSERT INTO @T ([Address]) VALUES 
('c. Paris, s. ParisDowntown, str. Rue Étienne Marcel, nr. 50');

The query:

SELECT City, CitySector, Street, Number
FROM @T
CROSS APPLY OPENJSON('{"' + REPLACE(REPLACE([Address], ', ', '", "'), '. ', '":"') + '"}') 
WITH (
    City nvarchar(100) '$.c',
    CitySector nvarchar(100) '$.s',
    Street nvarchar(100) '$.str',
    Number int '$.nr'
) As vals

Results:

City    CitySector      Street              Number
Paris   ParisDowntown   Rue Étienne Marcel  50
