Sql 总共得到两个不同的列

我需要生成两个不同列的总和

我的问题是这样的

SELECT 0 AS OTHER_AMT, ABS([MISC AMT]*100) AS MISC_AMT FROM ESCHEATMENT_FINAL WHERE [TRAN DT] < '6/30/2012' AND [MISC AMT]<>0

UNION ALL

SELECT ABS([DEP AMT]*100+[INT AMT]*100) AS OTHER_AMT, 0 AS MISC_AMT FROM [CCC_Escheatment].[dbo].[ESCHEATMENT_FINAL] WHERE [TRAN DT] < '6/30/2014' AND [DEP AMT]<>0

---

我需要杂项金额和其他金额的合计金额。我该怎么做呢

谢谢，我很感激！

select sum(other_amt) + sum(misc_amt) from (
    SELECT 0 AS OTHER_AMT, ABS([MISC AMT]*100) AS MISC_AMT FROM ESCHEATMENT_FINAL WHERE [TRAN DT] < '6/30/2012' AND [MISC AMT]<>0

    UNION ALL

    SELECT ABS([DEP AMT]*100+[INT AMT]*100) AS OTHER_AMT, 0 AS MISC_AMT FROM [CCC_Escheatment].[dbo].[ESCHEATMENT_FINAL] WHERE [TRAN DT] < '6/30/2014' AND [DEP AMT]<>0
)
