    【Question】
    Among the sets in the block "Ice Age", how many of them have an Italian translation? sets in the block "Ice Age" refers to block = 'Ice Age'; Italian translation refers to language = 'Italian' and translation is not null

    【Evidence】
    sets in the block "Ice Age" refers to block = 'Ice Age'; Italian translation refers to language = 'Italian' and translation is not null

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

SQL: SELECT COUNT(DISTINCT T1.id) FROM sets AS T1 INNER JOIN set_translations AS T2 ON T2.setCode = T1.code WHERE T1.block = 'Ice Age' AND T2.language = 'Italian' AND T2.translation IS NOT NULL
