What would be the best approach to just return the characters after the last special character (-) in a string?
Example:
ReportServer-SalesOrders
ReportServer-OKLA-SalesOrders
I only want to return "SalesOrders". Any help will be appreciated.
Thanks

This is most likely not the "best"

DECLARE @x table (y varchar(100));

INSERT INTO @x VALUES

('ReportServer-SalesOrders'),

('ReportServer-OKLA-SalesOrders');

SELECT REVERSE(left(REVERSE(Y), charindex('-', REVERSE(y))-1)) FROM @x;

Here are 2 additional options:

Note that PARSENAME can return incorrect results if you have dots in your values or if you have more than 4 sections.

DECLARE @x table (y varchar(100));

INSERT INTO @x VALUES

('ReportServer-SalesOrders'),

('ReportServer-OKLA-SalesOrders');

SELECT REVERSE(left(REVERSE(Y), charindex('-', REVERSE(y))-1)) ,

RIGHT(Y, charindex('-', REVERSE(y))-1),

PARSENAME( REPLACE( y, '-', '.'),1)

FROM @x;

Thanks for the feedback. Works like a charm!

Another thing, all the options so far (except the parsename) will fail if there isn't a '-'.

My preference is generally to use STUFF, but it's much the same as the others.

WITH sample AS (

SELECT *

FROM (VALUES('something-result'),('noresult'),('need-this-result'))s(Val)

)

SELECT NULLIF(

STUFF(Val,1,len(Val)-Charindex('-',reverse(Val))+1,'')

,'')

FROM sample

Why do I always forget the safety net? I live on the edge. :hehe:

DECLARE @x table (y varchar(100));

INSERT INTO @x VALUES

('ReportServer-SalesOrders'),

('ReportServer-OKLA-SalesOrders'),

('SalesOrders');

SELECT REVERSE(left(REVERSE(Y), charindex('-', REVERSE(y) + '-')-1)) ,

RIGHT(Y, charindex('-', REVERSE(y) + '-')-1),

PARSENAME( REPLACE( y, '-', '.'),1)

FROM @x;
