# sys.sensitivity_classifications (Transact-SQL)
[!INCLUDE[tsql-appliesto-xxxxxx-asdb-asdw-xxx-md](../../includes/tsql-appliesto-xxxxxx-asdb-asdw-xxx-md.md)]

Returns a row for each classified item in the database.

|Column name|Data type|Description|
|-----------------|---------------|-----------------|  
|**class**|**int**|Identifies the class of the item on which the classification exists. Will always have the value 1 (representing a column)|  
|**class_desc**|**varchar(16)**|A description of the class of the item on which the classification exists. will always have the value *OBJECT_OR_COLUMN*|  
|**major_id**|**int**|Represents the ID of the table containing the classified column, corresponding with sys.all_objects.object_id|  
|**minor_id**|**int**|Represents the ID of the column on which the classification exists, corresponding with sys.all_columns.column_id|   
|**label**|**sysname**|The label (human readable) assigned for the sensitivity classification|  
|**label_id**|**sysname**|An ID associated with the label, which can be used by an information protection system such as Azure Information Protection (AIP)|  
|**information_type**|**sysname**|The information type (human readable) assigned for the sensitivity classification|  
|**information_type_id**|**sysname**|An ID associated with the information type, which can be used by an information protection system such as Azure Information Protection (AIP)|  
|**rank**|**int**|A numerical value of the rank: <br><br>0 for NONE<br>10 for LOW<br>20 for MEDIUM<br>30 for HIGH<br>40 for CRITICAL| 
|**rank_desc**|**sysname**|Textual representation of the rank:  <br><br>NONE, LOW, MEDIUM, HIGH, CRITICAL|  
| &nbsp; | &nbsp; | &nbsp; |

## Remarks  

- This view provides visibility into the classification state of the database. It can be used for managing the database classifications, as well as for generating reports.
- Currently only classification of database columns is supported.
 
## Examples

### A. Listing all classified columns and their corresponding classification

The following example returns a table listing the table name, column name, label, label ID, information type, information type ID for each classified column in the database.

> [!NOTE]
> Label is a keyword for Azure SQL Data Warehouse.

```sql
SELECT
    SCHEMA_NAME(sys.all_objects.schema_id) as SchemaName,
    sys.all_objects.name AS [TableName], sys.all_columns.name As [ColumnName],
    [Label], [Label_ID], [Information_Type], [Information_Type_ID], [Rank], [Rank_Desc]
FROM
          sys.sensitivity_classifications
left join sys.all_objects on sys.sensitivity_classifications.major_id = sys.all_objects.object_id
left join sys.all_columns on sys.sensitivity_classifications.major_id = sys.all_columns.object_id
                         and sys.sensitivity_classifications.minor_id = sys.all_columns.column_id
```

## Permissions  
 Requires the **VIEW ANY SENSITIVITY CLASSIFICATION** permission.
