Can SQL Server 2008 use a variable in a WHERE IN clause

Are there any updates in SQL Server 2008 to allow a variable for the IN clause of a WHERE predicate?

Will this code work as expected?

declare @InParams varchar(100) = '1,2';

select * from Catego开发者_StackOverflow中文版ry
where CategoryID in @InParams;

See here: Arrays and Lists in SQL Server (pick your version), or here http://www.sommarskog.se/dynamic_sql.html

No - still need to use either:

• a split function, Table Valued CLR or Table Valued function
• dynamic SQL
