Failure inserting into the read-only column and SET IDENTITY_INSERT ON
06 December,2014 by Tom Collins
Question: I’m using the Import and Export Wizard to transfer data and complete a Data Import from one SQL table to another SQL table. The job keeps failing with this SQL error message reported:
Messages Error 0xc0202049: Data Flow Task 1: Failure inserting into the read-only column "ItemID". (SQL Server Import and Export Wizard)
Error 0xc0202045: Data Flow Task 1: Column metadata validation failed. (SQL Server Import and Export Wizard)
It looks like I can’t import identity columns and timestamp columns. How can I fix?
Answer: The workaround for this problem is to use SET IDENTITY_INSERT ON. This code will allow values to INSERT into a table identity column.
How to use SET IDENTITY_INSERT ON
SET IDENTITY_INSERT MyTable ON ---Complete the Import Operations ---When Data import completes set identity insert off SET IDENTITY_INSERT Mytable OFF
