Cannot insert explicit value for identity column in table "table" when IDENTITY_INSERT is set to OFF
🔥 How to Fix "Cannot Insert Explicit Value for Identity Column" Error in SQL Server 🔥
Are you getting the dreaded "Cannot insert explicit value for identity column" error in SQL Server? Don't sweat it! We've got you covered with easy solutions to fix this annoying problem. 💪
🤔 What's the error all about?
The error message "Cannot insert explicit value for identity column in table 'table' when IDENTITY_INSERT is set to OFF" means that you're trying to insert a value into an identity column explicitly. Identity columns are auto-incrementing columns that are usually used as primary keys in a table. They automatically generate unique values when new rows are inserted.
By default, SQL Server doesn't allow you to insert explicit values into identity columns. But fear not, we'll show you how to fix it in a jiffy! 😎
💡 Common Issues
Here are some common scenarios where you might encounter this error:
Scenario 1: Explicitly setting a value for an identity column
INSERT INTO table (Column1, IdentityColumn) VALUES ('Value1', 42)In this case, you're explicitly setting a value (42) for the identity column, which causes the error.
Scenario 2: Using SET IDENTITY_INSERT OFF
SET IDENTITY_INSERT table ON
-- Some other operations
INSERT INTO table (Column1, IdentityColumn) VALUES ('Value1', 42)
SET IDENTITY_INSERT table OFFHere, you've enabled IDENTITY_INSERT for the table, but you forgot to turn it off after the operation. This can cause issues when trying to insert rows into other tables with identity columns.
🔧 Easy Solutions
Solution 1: If you don't need to explicitly insert values into the identity column, simply remove the identity column from your INSERT statement. SQL Server will automatically generate a unique value for it.
INSERT INTO table (Column1) VALUES ('Value1')Solution 2:
If you must explicitly insert a value into the identity column, you can enable IDENTITY_INSERT for the table before the insert operation and then turn it off afterwards.
SET IDENTITY_INSERT table ON
INSERT INTO table (Column1, IdentityColumn) VALUES ('Value1', 42)
SET IDENTITY_INSERT table OFF📣 Call-to-Action
