For a description of the columns that the sys.computed_columns view inherits from sys.columns, see sys.columns (Transact-SQL). The value of the is_computed column is always set to 1 in the sys.computer_columns view.|
|definition||nvarchar(max)||SQL text that defines this computed-column.|
|uses_database_collation||bit||1 = The column definition depends on the default collation of the database for correct evaluation; otherwise, 0. Such a dependency prevents changing the database default collation.|

The visibility of the metadata in catalog views is limited to securables that a user either owns or on which the user has been granted some permission. For more information, see Metadata Visibility Configuration.
