解决方法
你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
如果您在“YourOtherBigTable”中有Identity In On，并且列完全相同，那么你会没事的。
