Matching string removal from another column

Question

I am working in SQL Server 2014. I have 2 columns in a table named Gallery Name and Address . Below is my sample data from this table.

Gallery Name           Address
--------------------------------------------------------------
Boltelang              Boltelang street 12, Paris
BERG Contemporary      BERG Contemporary gorge ave, New York

Like this, I have a total of 207 records. Now the issue is that the data of column Gallery Name is being repeated in address column which I want to remove from address column. So it should be like this in

Gallery Name          Adress
--------------------------------------------
Bltelang              street 12, Paris
BERG Contemporary     gorge ave, New York

I have no clue which function I can use in SQL Server to achieve this

Answer 1

Answer to your query is to use REPLACE like following.

UPDATE TABLE_NAME 
SET [Address] = REPLACE([Address], [Gallery Name],'')

Note : In above query, REPLACE will replace all the occurrences of [Gallery Name] in [Address].

There can be scenario where you need to replace only the first occurance , not if it exists somewhere in the middle. In that case you can try like following.

 UPDATE T SET  [Address]= 
         LTRIM(STUFF([Address], CHARINDEX([Gallery Name], [Address]), LEN([Gallery Name]), ''))
    from TABLE_NAME T
    WHERE [Address] LIKE [Gallery Name] +'%'

Answer 2

I would go for:

update t
    set address = stuff(address, 1, len(gallery_name) + 1, '')
    where address like gallery_name + ' %';

These cover the examples in your question, where the gallery name is at the beginning of the address followed by a space. I am very conservative in making such changes. If you have another pattern, then you can run another update to fix those.

You want to be careful using REPLACE() , in case the address repeats the gallery name:

New York     New York 10 New York Ave

Answer 3

Assuming it's only needed when the "Gallery Name" is at the start of the "Address".

To correct the addresses in the table

UPDATE [YourTable]
SET [Address] = LTRIM(REPLACE([Address], [Gallery Name],''))
WHERE [Address] LIKE CONCAT([Gallery Name],'%')
