从MS SQL Server 2008中的源表中仅向N表添加N行

Question

我想使用

从源表中仅将N行插入新表

Select * into NewTable from SourceTable where ......

我不知道源表列

Answer 1

Select * into NewTable...将创建new table [您无法将数据插入到这样的现有表中。您必须使用insert into...]

如果要插入N行，请尝试;

select top N * into NewTable sourcetable where ...

Answer 2

SELECT * INTO NewTable
FROM
(
    SELECT *, ROW_NUMBER() OVER (ORDER BY (SELECT 100)) AS Row
    FROM SourceTable
) t
WHERE t.Row <= N
