Sql-server – Database-wide equivalent of SET IDENTITY_INSERT OFF

identityidentity-insertsql server

In my eternal saga to insert 1.4 million rows of data from a SQL script, I've written a basic WinForms app that takes each line of the script and executes it individually.

However, because the original script contained

SET IDENTITY_INSERT [Table] OFF

and SET is a session-wide command, this setting is getting lost on every SQL call, meaning that each line is failing. Is there a way to set IDENTITY_INSERT off for the whole table, database-wide just so I can make these individual calls without them failing? Or perhaps I can tell it to ignore the identity specification by appending a command to each line?

BULK INSERT won't work for you? Or the SQL Server Import/Export Wizard (here or here)? I know import/export can turn off identity insert for the whole import. I'm reasonably certain you can do it just prior to BULK INSERT

Sql-server – Turn off IDENTITY_INSERT for Dataset insert

You have the options mixed up:

SET IDENTITY_INSERT orders ON

will turn ON the ability to insert specific values (that you specify) into a table with an IDENTITY column.

SET IDENTITY_INSERT orders OFF

Turns that behavior OFF again and the normal behavior (you can't specify values for IDENTITY columns since they are auto-generated) is reinstated.
