Question

我有一个表Persons (ID, Name, Address)和另一个表Persons_twin (ID, Name, Address)，其中我要从Persons复制整行。

哪种方法是复制数据的最短最好的方法？下面是我尝试的代码，但没有执行。您的建议最有价值。谢谢。

BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    SET NOCOUNT ON;

    -- Insert statements for procedure here
    INSERT INTO [dbo].[Persons_twin](ID, Name, Address)
    VALUES(SELECT ID, Name, Address FROM [dbo].[Persons])
END

select

Answer 2

如果两个表都相同，则可以使用此查询：

INSERT INTO Persons_twin
SELECT * FROM Persons

Answer 3

您甚至可以创建第二个表即时。在这种情况下，您不必担心表的结构：

SELECT * INTO persons_twin FROM Persons

使用SQL将整个数据从一个表复制到另一个表的存储过程
