I have a new clustered database and I’ve been moving data into the tables from our old database. When I import the data, everything works fine, but when I manually insert a record the Identity column does not follow the next identity number. So, for example, I import 100 records into the table and the Identity column shows 1-100, but if I then manually add a row to the database, I’ll get 102 or 103, not 101.
Any ideas why this is happening?
It is happening across all of my tables and it’s getting very frustrating as sometimes the gap between Identities is up to 4 or 5.
If you “test” your insert within a transaction and a rollback. And then you run it for real. The insert within the transaction will increment the identity field by one, even if you then rollback.
