.net sql sever 当 IDENTITY_INSERT 设置为 OFF 时,不能为表 'Archives' 中的标识列插入显式值。 60

}在数据库中有一个字段 datapartyid 是自增的 ,但是我的增加语句中没有给datapartyid 赋值, 还是出现错误!
我在数据库里直接添加是可以成功的 在。net里就不行 展开

太简单了。把表的IDCard 为自动增长给去掉,或者把语句改为:
strSql.Append("insert into Archives(");
strSql.Append("Name,Password,Gender,Age,Education,Height,DateOfBirth,Native,Degree,Major,Title,Post)");
strSql.Append(" values (");
strSql.Append("@Name,@Password,@Gender,@Age,@Education,@Height,@DateOfBirth,@Native,@Degree,@Major,@Title,@Post)");
OK。搞定
strSql.Append("insert into Archives(");
strSql.Append("Name,Password,Gender,Age,Education,Height,DateOfBirth,Native,Degree,Major,Title,Post)");
strSql.Append(" values (");
strSql.Append("@Name,@Password,@Gender,@Age,@Education,@Height,@DateOfBirth,@Native,@Degree,@Major,@Title,@Post)");
OK。搞定

idcard不是自增 自增的datapartyid已经去掉了

set IDENTITY_INSERT ArchivesON
IDCard 为自动增长 不需要插入 去掉这一列 即可!!!!
