SELECT * FROM TABLE
WHERE (CASE WHEN ISNULL(@P_NAME,'') = '' THEN '' ELSE NAME END)= ISNULL(@P_NAME,'')
AND (CASE WHEN ISNULL(@P_CITY,'') = '' THEN '' ELSE CITY END)= ISNULL(@P_CITY,'')
AND (CASE WHEN ISNULL(@P_STATE,'') = '' THEN '' ELSE STATE END)= ISNULL(@P_STATE,'')

Thus if you ask 
@P_Name = 'xxx'
@P_CITY = NULL
@P_STATE = 'yyyy'
