Settings
The NotifyMethod argument is a bit-packed long integer. Use an OR logical operator to specify more than a single value. Set the NotifyMethod argument using these values.
| Constant | Value | Description | 
|---|---|---|
| SQLDMONotify_All | 7 | Notification by e-mail, e-mail sent to the pager address, and network pop-up message. | 
| SQLDMONotify_Email | 1 | Notification by e-mail sent to the operator e-mail address. | 
| SQLDMONotify_NetSend | 4 | Notification by network pop-up message posted to the operator network address. | 
| SQLDMONotify_Pager | 2 | Notification by e-mail sent to the operator pager address. | 
Set the EnumNotifyType argument using these values.
| Constant | Value | Description | 
|---|---|---|
| SQLDMOEnumNotify_/Actual | 2 | Return only those operators or alerts configured for notification. | 
| SQLDMOEnumNotify_All | 1 | Return all operators or alerts. The value of the use_email, use_netsend, or use_pager column indicates that the operator or alert is configured for notification by the indicated method. | 
| SQLDMOEnumNotify_Max | 3 | SQLDMOEnumNotify_Target. | 
| SQLDMOEnumNotify_Min | 1 | SQLDMOEnumNotify_All. | 
| SQLDMOEnumNotify_/Target | 3 | Return a result set that enumerates notification for the operator or alert specified in the AlertOrOperator argument. |

| has_pager | integer | When 1, the operator is configured with a pager address. | 
| operator_id | integer | System-generated operator identifier. | 
| operator_name | nvarchar(129) | Operator name. | 
| use_email | integer | Column present when NotifyMethod specifies SQLDMONotify_Email. When 1, the operator is configured to receive notification by e-mail. | 
| use_netsend | integer | Column present when NotifyMethod specifies SQLDMONotify_NetSend. When 1, the operator is configured to receive notification by network pop-up message. | 
| use_pager | integer | Column present when NotifyMethod specifies SQLDMONotify_Pager. When 1, the operator is configured to receive notification by page. |
