这个代码 在加一列写成视图形式怎么写呀

 SELECT     CONVERT(NVARCHAR, RH.REQ_ID) + '-' + CONVERT(NVARCHAR, EEO.EXP_TYPE) + CONVERT(NVARCHAR, EEO.CURRENCY_TYPE) + '-S' AS ID, RH.REQ_ID, 
                      EEO.EXP_TYPE,EEO.ISHAVEBREAKFAST, EEO.CURRENCY_TYPE, SUM(EEO.EXP_PRICE) AS EXP_PRICE, SUM(EEO.RMB_PRICE) AS RMB_PRICE, SUM(EEO.ACT_EXP_PRICE) 
                      AS ACT_EXP_PRICE ,SUM(EEO.ACT_RMB_PRICE) AS ACT_RMB_PRICE, 'Total' AS CONTENT, '' AS MEMO
FROM         REQUEST_HEAD RH, EXP_EVECTION_OTHERS EEO
WHERE     RH.REQ_ID = EEO.REQ_ID
GROUP BY RH.REQ_ID, EEO.EXP_TYPE, EEO.CURRENCY_TYPE
UNION
SELECT     CONVERT(NVARCHAR, RH.REQ_ID) + '-' + CONVERT(NVARCHAR, EEO.EXP_TYPE) + '-' + CONVERT(NVARCHAR, EEO.EXP_ID) AS ID, RH.REQ_ID, EEO.EXP_TYPE, 
                      EEO.CURRENCY_TYPE, EEO.EXP_PRICE, EEO.RMB_PRICE, EEO.ACT_EXP_PRICE,EEO.ISHAVEBREAKFAST, EEO.ACT_RMB_PRICE, CONVERT(NVARCHAR(10), EEO.OCCUR_DATE, 120) 
                      AS CONTENT, EEO.EXP_DESC AS MEMO
FROM         REQUEST_HEAD RH, EXP_EVECTION_OTHERS EEO
WHERE     RH.REQ_ID = EEO.REQ_ID;

在加一列 （EXP_EVECTION_OTHERS这个表中的别名EEO的 ISHAVEBREAKFAST这个列 怎么写呀 求各位大神帮忙）
