Contains a row for each column found in sys.columns that is a computed-column.
| Column name | Data type | Description |
|---|---|---|
| <Inherited columns> | The sys.computed_columns view returns all columns in the sys.columns view. It also returns the additional columns described below. 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.computed_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. |
| is_persisted | bit | Computed column is persisted. |
