SQLSERVER2012 SQL语句修改标识列数据

2017-09-27

今天给客户导数据，内容表100万条记录，表字段不到100个。用程序分批导。

由于标识列 id 里的值有用，所以在导入时把id改为了不自增。导完后，再加为自增列时，提示超时。

用语句 alter table rcms_contents alter column [id] bigint identity(1,1) 修改，在sql08下提示语法错误。

标注：rcms_contents为源表；content为临时表

于是上网查，解决了。方法如下：

1、先把数据加到临时表里，一会儿会用到 select * into content from rcms_contents

2、先加一列id_1设为自增列 alter table rcms_contents add id_1 bigint identity(1,1)

3、（一定要备份数据库）然后把源表里的数据删掉 truncate table rcms_contents

4、打开此表设计，把id列改为自增，保存表

5、执行 set identity_insert rcms_contents on （可更改标识列）

6、设置表rcms_contents列id_1可以为空

7、用 insert into rcms_contents(字段) select 字段 from content 从临时表里进行导入数据

8、把可更改标识列的值关闭，执行 set identity_insert rcms_contents off

9、删除rcms_contents的id_1

这样就大功告成了。数据库方面还要再加强。
