Below code works for \'Main Stream\' or \'Premium\' as parameter, however I am trying to make it work for both of them as you can see below, but it doesn\'t return any resul

Answer 1

declare @myParameter varchar(50)
SET @myParameter = 'Main Stream , Premium'


select * FROM sales  
where myCategory IN (select * from string_split(@myParameter,','))
