# sys.sql_dependencies (Transact-SQL)
[!INCLUDE [SQL Server](../../includes/applies-to-version/sqlserver.md)]

  Contains a row for each dependency on a referenced entity as referenced in the [!INCLUDE[tsql](../../includes/tsql-md.md)] expression or statements that define some other referencing object.  
  
> [!IMPORTANT]  
>  [!INCLUDE[ssNoteDepFutureAvoid](../../includes/ssnotedepfutureavoid-md.md)] Use [sys.sql_expression_dependencies](../../relational-databases/system-catalog-views/sys-sql-expression-dependencies-transact-sql.md) instead.  

  
|Column name|Data type|Description|  
|-----------------|---------------|-----------------|  
|**class**|**tinyint**|Identifies the class of the referenced entity:<br /><br /> 0 = Object or column (non-schema-bound references only)<br /><br /> 1 = Object or column (schema-bound references)<br /><br /> 2 = Types (schema-bound references)<br /><br /> 3 = XML Schema collections (schema-bound references)<br /><br /> 4 = Partition function (schema-bound references)|  
|**class_desc**|**nvarchar(60)**|Description of class of referenced entity:<br /><br /> **OBJECT_OR_COLUMN_REFERENCE_NON_SCHEMA_BOUND**<br /><br /> **OBJECT_OR_COLUMN_REFERENCE_SCHEMA_BOUND**<br /><br /> **TYPE_REFERENCE**<br /><br /> **XML_SCHEMA_COLLECTION_REFERENCE**<br /><br /> **PARTITION_FUNCTION_REFERENCE**|

|**referenced_minor_id**|**int**|Minor-ID of the referenced entity, interpreted by value of class, as shown in the following.<br /><br /> When class =:<br /><br /> 0, **referenced_minor_id** is a column ID; or if not a column, it is 0.<br /><br /> 1, **referenced_minor_id** is a column ID; or if not a column, it is 0.<br /><br /> Otherwise, **referenced_minor_id** = 0.|
