I have 157 values (varchar) in a table but I am only interested in say 50 of these strings. So it's a simple where clause basically but I don't want to do 50 AND's, so I'm thinking about an IN operator on the where. Thing is I have two CTE's and I want to do this in BOTH CTE's.
Is there any way of storing all these values in something like an array and reusing it wherever I want in SQL Server?

Can you please post the DDL (create table) script, sample data as an insert statement and the desired results!

Yes, it's called a table. You can either store the values you're interested in in a table, temp table, or table variable or you can add a column to the current table to flag the ones that you are interested in.
