使用where子句将两个表中的数据合并到一个表中

Question

我有两个文件已批量导入到两个日期重叠的表中。现在我想将两个表中的数据移动到一个新表中，但删除重叠的日期。这是我的代码：

-- Pull across data from P1-10 and exclude out of scope dates
SELECT      *
INTO        I_Inventory
FROM        I_Inventory_P10_Temp
WHERE       [date] >= '01/01/2016' and [date] <= '10/31/16'

-- Pull across data from P11-12 and exclude out of scope dates
SELECT      *
INTO        I_Inventory
FROM        I_Inventory_P12_Temp
WHERE       [date] >= '11/01/2016' and [date] <= '12/31/16'

但是这不起作用，因为它说在第一次选择后表已经存在。有人可以让我知道如何解决这个问题吗？我对 SQL 很陌生。

Answer 1

使用UNION ALL合并结果，然后插入到表中

SELECT      *
INTO        I_Inventory
FROM        I_Inventory_P10_Temp
WHERE       [date] >= '01/01/2016' and [date] <= '10/31/16'
Union All
-- Pull across data from P11-12 and exclude out of scope dates
SELECT      *
FROM        I_Inventory_P12_Temp
WHERE       [date] >= '11/01/2016' and [date] <= '12/31/16'
