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

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 

How to Fix the Error 'Cannot insert explicit value for identity column , In the first case, we will insert data into the table with the “IDENTITY INSERT” set to “OFF”. So, if the ID is present into the INSERT statement, you will get the error “Cannot insert explicit value for identity column in table 'person' when IDENTITY_INSERT is set to OFF”. Execute the following code in the query tab. The problem with your description of what you want and what you actually have is that the IDENTITY specification is ever increasing and you cannot insert a value to it without IDENTITY_INSERT switched on for that field. You won't get Company_ID 1 having ID 1, 2, 3 and Company_ID 2 having ID 1,2,3 etc.

don't put value to OperationID because it will be automatically generated. try this:

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

Simply If you getting this error on SQL server then run this query-

SET IDENTITY_INSERT tableName ON

this is working only single table of databse e.g If table name is student then query look like this SET IDENTITY_INSERT student ON

If you getting this error on your web application or you using entity framework then first run this query on SQL server and Update your entity model (.edmx file) and build your project and this error will be resolved

Cannot Insert Explicit Value For Identity Column, The reason you're getting this error is because you are trying to tell SQL Server what the ID value for a row in the table should be. If you have an identity column on your table, SQL Server will want to generate that ID value for you automatically. Cannot insert explicit value for identity column in table 'mytable' when IDENTITY_INSERT is set to OFF. But a query like this will work: SET IDENTITY_INSERT mytable ON INSERT INTO mytable (VoucherID, name) VALUES (1, 'Cole') SET IDENTITY_INSERT mytable OFF;

Be very wary of setting IDENTITY_INSERT to ON. This is a poor practice unless the database is in maintenance mode and set to single user. This affects not only your insert, but those of anyone else trying to access the table.

Comments
  • Possible duplicate of SQL Server error: "Cannot insert explicit value for identity column" even when I SET IDENTITY_INSERT ON
  • @HimanshuAhuja This question (1334012) is 10 years old, the one you linked only 1. If anything, then the newer is a duplicate. But on closer look you will that they differ (the newer one specifies IDENTITY_INSERT as ON). Please delete your flag/comment.
  • @jasie will do that as I dont remember when i had posted this flag
  • +1 exactly - turn the option to allow explicit inserts ON, then insert, then turn the option OFF again
  • If you really want to add your value to the identity column, this is your answer, but on the other hand, someone have set the column to be incrementing by itself up on insert. In that case the table will keep track of the next free number, and you do not need to generate the OperationID by yourself. The new id can be fetched by SELECT SCOPE_IDENTITY().
  • Dangerous practice, do not recommend using it without caveats telling why it is a poor idea. Very poor answer.
  • good answer, but make sure you know what you are doing. For me it's useful to seed a database with data where the foreign keys need to match up over different tables
  • @UlyssesAlves: this option can only be turned on for a single table database-wide - so if you leave it on for one table, you won't be able to ever use it for another table. Also: it's not an option that should be left on - by default, you should let SQL Server handle identity values - this is only intended as a last resort measure for very specific cases - not a general-purpose option to leave on or off at your leisure...
  • this is the correct answer if you want automatically generated OperationID
  • It was the case in my MVC web app with EF and I just deleted the model from .edmx and re-added (Right Click Update Model From Database) and clean and rebuild the project which then worked for me. Thank you @Umang Patwa
  • Affects in what way? This is a session level option not a property of the table.
  • One time data sync between two databases that you want to maintain relationships. For example I used it to pull my product schema from one database to another
  • @NSjonas, that would be a good use of set Identity _insert table1 ON. I have seen people who wanted to use this to do something from the application that should be done with a simple insert and allowing the identity to get generated.
  • The question is "Could you specify what it is and how it can be resolved?" Your answer is a comment which raises a warning and another question instead of a proper answer that addresses the problem.
