将值从一列添加到另一列

Question

我有这样的疑问：

SELECT 
    CurrentAccountID
    , IncomeBYR + IncomeConvertBYR AS AmountBYR
    , IncomeUSD AS AmountUSD
    , [Date] AS ExecutionDate   
FROM CTE2
ORDER BY [Date]

我需要将AmountBYR和AmountUSD组合成一个具有相同日期的列。 结果集如下：

CurrentAccountID  AmountTotal  ExecutionDate
3                 2383410.00   2010-02-13
3                 -159     2010-02-13
...               ....          .....

在一个Select查询中存在某种方式吗？

Answer 1

我会使用UNION ALL。

像

这样的东西

SELECT 
    CurrentAccountID
    , IncomeBYR + IncomeConvertBYR AS AmountTotal
    , [Date] AS ExecutionDate   
FROM CTE2
UNION ALL
SELECT 
    CurrentAccountID
    , IncomeUSD AS AmountTotal
    , [Date] AS ExecutionDate   
FROM CTE2
ORDER BY [Date]
