# ADCPROP_UPDATECRITERIA_ENUM
Specifies which fields can be used to detect conflicts during an optimistic update of a row of the data source with a [Recordset](../../../ado/reference/ado-api/recordset-object-ado.md) object.  
  
 Use these constants with the **Recordset** "**Update Criteria**" dynamic property, which is referenced in the [ADO Dynamic Property Index](../../../ado/reference/ado-api/ado-dynamic-property-index.md) and documented in the [Microsoft Cursor Service for OLE DB](../../../ado/guide/appendixes/microsoft-cursor-service-for-ole-db-ado-service-component.md) documentation.  
  
|Constant|Value|Description|  
|--------------|-----------|-----------------|  
|**adCriteriaAllCols**|1|Detects conflicts if any column of the data source row has been changed.|  
|**adCriteriaKey**|0|Detects conflicts if the key column of the data source row has been changed, which means that the row has been deleted.|  
|**adCriteriaTimeStamp**|3|Detects conflicts if the timestamp of the data source row has been changed, which means the row has been accessed after the **Recordset** was obtained.|  
|**adCriteriaUpdCols**|2|Detects conflicts if any of the columns of the data source row that correspond to updated fields of the **Recordset** have been changed.|
