sqlserver中set IDENTITY_INSERT on 和 off 的设置方法:

执行插入数据库插入数据时报了以下错误，我明明没有给主键set值但还是报错

解决方法如下:

qlserver 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 )
