    【Question】
    How many cities are in U.A.E? U.A.E refers to Country_Name = 'U.A.E'

    【Evidence】
    U.A.E refers to Country_Name = 'U.A.E'

    Please read and understand the database schema carefully, and generate an executable SQL based on the user's question and evidence. 

SQL: SELECT SUM(CASE WHEN T2.Country_Name = 'U.A.E' THEN 1 ELSE 0 END) FROM City AS T1 INNER JOIN country AS T2 ON T1.Country_id = T2.Country_id
