当 IDENTITY_INSERT 设置为 OFF 时，无法在表“表"中插入标识列的显式值

I have the below error when I execute the following script. What is the error about, and how it can be resolved?

Insert table(OperationID,OpDescription,FilterID)
values (20,'Hierachy Update',1)

Error:

Server: Msg 544, Level 16, State 1, Line 1

Cannot insert explicit value for identity column in table 'table' when IDENTITY_INSERT is set to OFF.

解决方案

You're inserting values for OperationId that is an identity column.

You can turn on identity insert on the table like this so that you can specify your own identity values.

SET IDENTITY_INSERT Table1 ON

INSERT INTO Table1
/*Note the column list is REQUIRED here, not optional*/
            (OperationID,
             OpDescription,
             FilterID)
VALUES      (20,
             'Hierachy Update',
             1)

SET IDENTITY_INSERT Table1 OFF
