Numeric alias
The numeric value 81 doesn't have its own canonical entry — it's defined symbolically:
- UNKNOWN_DATABASE Unknown database The specified database does not exist on this server. Create the database first or check for a typo in the database name.
- FENCED_INSTANCE_ID Fenced Instance ID The static member's instance ID has been fenced by a newer member with the same instance ID. The fenced member must rejoin.
