SQL Server error 1976

SQL Server raises error 1976 at severity 16, which marks a problem with the query or data that you can correct.

Cannot create index or statistics '%.*ls' on view '%.*ls' because cannot verify key column '%.*ls' is precise and deterministic. Consider removing column from index or statistics key, marking column persisted in base table if it is computed, or using non-CLR-derived column in key.
