自增字段中插入指定值 set IDENTITY_INSERT on 和 off 的设置

如何自增字段中插入指定值 set IDENTITY_INSERT on 和 off 的设置
sqlserver 批量插入记录时,对有标识列的字段要设置 set IDENTITY_INSERT 表名 on,然后再执行插入记录操作;插入完毕后恢复为 off 设置

格式:
  set IDENTITY_INSERT 表名 on
  set IDENTITY_INSERT 表名 off

举例:

set IDENTITY_INSERT peoplePworkpositiontype  on
insert peoplePworkpositiontype(id,workpositiontype,workpositiontypeid) values(1 , '平台' , 1 )
insert peoplePworkpositiontype(id,workpositiontype,workpositiontypeid) values(2 , '陆地' , 2 )
insert peoplePworkpositiontype(id,workpositiontype,workpositiontypeid) values(3 , '海上' , 3 )

go
set IDENTITY_INSERT peoplePworkpositiontype  off


set IDENTITY_INSERT peoplePstatetype  on
insert peoplePstatetype(id,nowstatetype,nowstatetypeid) values(1 , '出海' , 1 )
insert peoplePstatetype(id,nowstatetype,nowstatetypeid) values(2 , '出差' , 2 )
insert peoplePstatetype(id,nowstatetype,nowstatetypeid) values(3 , '公司' , 3 )
insert peoplePstatetype(id,nowstatetype,nowstatetypeid) values(4 , '会议' , 4 )
go
set IDENTITY_INSERT peoplePstatetype  off
go
