使用結果，形成另一個查詢

Question

我有兩個疑問其中一個依賴於輸入從其他的一部分：

查詢＃1：

SELECT ACCOUNT_ID 
FROM ISET.ACCOUNT 
WHERE HOLDER='12345' 

這將返回的ACCOUNT_ID列表與持有人相關12345

然後我需要把這些account IDs傳遞到下面的查詢，以顯示與所有的帳戶ID關聯交易的列表撿到

SELECT TRANS_ID, ACCOUNT_ID, "REF" 
FROM ISET.ENTRY 
WHERE ACCOUNT_ID='LIST OF ACCOUNT IDS'; 

我該如何找到最有效的方法？

感謝您的期待。
