Question

I need to trim ; from a string inside T-SQL. But only if it has it. Like below :

DECLARE @_tags AS NVARCHAR(MAX);
SET @_tags = 'bla; bla;';

--SELECT TRIMEND(@_tags, ';');

So, if @_tags ends with ;, ; will be trimmed. How can I do that?

Answer 1

To remove all if last char is ;:

SELECT 
   CASE
       WHEN RIGHT(@_tags, 1) = ';' THEN REPLACE (@_tags, ';', '')
       ELSE @_tags
   END

To remove the end one only:

SELECT 
   CASE
       WHEN RIGHT(@_tags, 1) = ';' THEN STUFF(@_tags, LEN(@_tags), 1, '')
       ELSE @_tags
   END
