Contains a row for each statistics object that exists for the tables, indexes, and indexed views in the database.
Note
Every index will have a corresponding statistics row with the same name and ID (index_id = stats_id), but not every statistics row has a corresponding index.
The catalog view, sys.stats_columns, provides statistics information for each column in the database. For more information, see sys.stats_columns (Transact-SQL)
For more information about statistics, see Statistics.
