Query for multiple value search

Question

Hi
I got struck when I try to construct SQL query to fetch multiple values in WHERE clause.
SELECT columnName from someTable
WHERE someValue = {here is the problem, I have multiple values here which I get from some array}
Is there any way I can put multiple values to where clause?
