Hi All,
I have an Address column that I need to Substring. I want to remove part of the string after either, or both of the following characters i.e ',' OR '*'
Example Record 1. Elland **REQUIRES BOOKING IN***
Example Record 2. Theale, Nr Reading, Berkshire
Example Record 3. Stockport
How do I achieve this in a CASE Statement?
The following two case statements return the correct results, but I some how need to combine them into a single Statement?
,LEFT(Address ,CASE WHEN CHARINDEX(',',Address) =0
THEN LEN(Address )
ELSE CHARINDEX(',' ,Address ) -1 END) AS 'Town Test'
,LEFT(Address ,CASE WHEN CHARINDEX('*',Address ) =0
THEN LEN(Address)
ELSE CHARINDEX('*' ,Address ) -1 END) AS 'Town Test2'
Thanks in advance

What is the difference between 'Town' and 'Address' and which is the sample data referring to?

Hi,

Sorry typo on my part. Address/Town are the same column.

The examples are sample records found in the Address Column.

Thanks

OK. Here is a hack for you.

with addresses

as (select address = 'Elland **REQUIRES BOOKING IN***'

union all

select 'Theale, Nr Reading, Berkshire'

union all

select 'Stockport'

)

select *

,left(address, case when charindex(',', address) = 0 then len(address)

else charindex(',', address) - 1

end) as 'Town Test'

,left(address, case when charindex('*', address) = 0 then len(address)

else charindex('*', address) - 1

end) as 'Town Test2'

,left(address, case when charindex(',', replace(address,'*',',')) = 0 then len(address)

else charindex(',', replace(address,'*',',')) - 1

end) as 'Town Test3'

from addresses;

If you just need whichever comes first, I suggest:

with addresses

as (select address = 'Elland **REQUIRES BOOKING IN***'

union all

select 'Theale, Nr Reading, Berkshire'

union all

select 'Stockport'

)

select address

,left(address, PATINDEX('%[,*]%', address + ',') - 1) as address_trimmed

from addresses;
