Adding columns to a replicated table

Mon, 01 Jan 0001 00:00:00 +0000

When you add tables to transactional replication and you want replication to propagate column additions made by third-party applications, you can run into a permission problem.

By default, replication requires the user who alters the table and adds a column to be either sysadmin or db_owner.

You may well have applications that do not hold those permissions and still need to add columns to replicated tables.

To work around this, we can bend the database DDL trigger that fires on ALTER TABLE, adding the EXECUTE AS SELF option to it. When you make that change you must be sysadmin or db_owner yourself: EXECUTE AS SELF makes the trigger run under the same execution context as the one you had when you altered it.
