插入多个表相同的字段（以更有效的方式）

Question

我期待避免重写下同查询（每个唯一表）：

Insert Into dbo.DatabaseNEW (Field1 , Field 2) 
Select Field 1, Field 2 FROM OldDatabase.dbo.[Table 1] WHERE DESCRIPTION LIKE 'Something'; 

Insert Into dbo.DatabaseNEW (Field1 , Field 2) 
Select Field 1, Field 2 FROM OldDatabase.dbo.[Table 2] WHERE DESCRIPTION LIKE 'Something'; 

我试着查询相结合的下面，但它不起作用：

Insert Into dbo.DatabaseNEW (Field1 , Field 2) 
Select Field 1, Field 2 FROM OldDatabase.dbo.[Table 1], OldDatabase.dbo.[Table 2] WHERE DESCRIPTION LIKE 'Something'; 

任何帮助吗？对于noob问题抱歉。谢谢！

Answer 1

你可以使用UNION ALL操作

Insert Into dbo.DatabaseNEW (Field1 , Field2) 
(
Select Field1, Field2 FROM OldDatabase.dbo.[Table 1] WHERE DESCRIPTION LIKE 'Something' 
UNION ALL 
Select Field1, Field2 FROM OldDatabase.dbo.[Table 2] WHERE DESCRIPTION LIKE 'Something' 
);
