'insert into'from more source-tables

Question

我想從三個不同的表中插入一個表， 但下面的第一條語句有效，下一條不會。 我該怎麼辦？

SELECT * into NewTable from ta where farm like'%aa'; 
SELECT * into NewTable from tb where farm like'%aa'; 
SELECT * into NewTable from tc where farm like'%aa'; 

Answer 1

嘗試這種方式

select * into NewTable from (
SELECT * from ta where farm like'%aa' 
Union all 
SELECT * from tb where farm like'%aa' 
Union all 
SELECT * from tc where farm like'%aa' 
)a; 

Answer 2

查詢select * into NewTable其實按SELECT查詢的結果產生是NewTable然後插入這些結果。

因此，爲了第一次查詢後插入到表存在，改變第二和第三個以

insert into NewTable 
select * from tb ... 

insert into NewTable 
select * from tc ... 

注意 - 在這種情況下，所有表都應該具有相同的結構。

Answer 3

代替三個刀片最好做一個和UNION結果：

SELECT * into NewTable 
from ta 
where farm like'%aa' 

UNION ALL 

SELECT * 
from tb 
where farm like'%aa' 

UNION ALL 

SELECT * 
from tc 
where farm like'%aa'; 

Answer 4

下一次，我wan't 選擇*到newtable中從 SELECT * FROM td農場如'％aa' 顯示錯誤：NewTable已存在。
