您实际上可以很容易地做到这一点：
-- Select everything into temp table
Select * Into
#tmpBigTable
From [YourBigTable]
-- Drop the Primary Key Column from the temp table
Alter Table #tmpBigTable Drop Column [PrimaryKeyColumn]
-- Insert that into your other big table
Insert Into [YourOtherBigTable]
Select * From #tmpBigTable
-- Drop the temp table you created
Drop Table #tmpBigTable
只要您在“ YourOtherBigTable”中具有“身份插入”且列完全相同，就可以了。
