create table tab(id int identity,col varchar(20)) insert tab select '123' union all select 'asdf' union all select '8866' union all select 'dfo' union all select 'dwoie' union all select 'fow' go delete tab where id=5 select * from tab go set identity_insert tab on insert tab(id,col) select 5,'dfa' set identity_insert tab off go select * from tab
证明一切................但是在一个数据库中只能同时只能设置一个set identity_insert 表 on
