How do I disable not for replication option for the identity column?
Set Tables Identity Column to Not For Replication for SQL Server 2005 and later. In SQL Server 2005 and later a system stored procedure has been created to allow you to turn on or turn off this “Not For Replication” setting. This new stored procedure is sys. sp_identitycolumnforreplication.
How do you change columns to identity?
You cannot alter a column to be an IDENTITY column. What you’ll need to do is create a new column which is defined as an IDENTITY from the get-go, then drop the old column, and rename the new one to the old name.
What does not for replication mean?
“Not for Replication” is a property which can be set for different objects like Check constraints, Foreign Key constraints, Triggers , Identity columns etc while using SQL Server Replication.
What is identity column in SQL?
An identity column is a column (also known as a field) in a database table that is made up of values generated by the database. This is much like an AutoNumber field in Microsoft Access or a sequence in Oracle. In Microsoft SQL Server you have options for both the seed (starting value) and the increment.
What does not for replication do on identity column?
Replication sets the NOT FOR REPLICATION option on the identity column at the Subscriber, so that only user inserts cause the value to be incremented at the Subscriber. Note. Subscribers must synchronize with the Publisher to receive new ranges.
Can you add an identity column to a published table?
Replication handles identity columns across all publication and subscription types, allowing you to manage the columns manually or have replication manage them automatically. Adding an identity column to a published table is not supported, because it can result in non-convergence when the column is replicated to the Subscriber.
How to reseed an identity column in SQL 2005?
You can do it on sql 2005 and up dynamically (without affecting replication) using sys.sp_identitycolumnforreplication. If you are not updating the data on subscriber side, you should be fine. Say we were to reseed an Identity Column on a Table on Server A (for whatever reason), how would this affect the data on Server B?
Why are the values in the identity column different?
The values in the identity column at the Publisher depend on the order in which the rows for the affected table are physically stored. The rows might be stored differently at the Subscriber; therefore the value for the identity column can be different for the same rows.
