Input Parameter
| Input Parameter | Description |
|---|---|
| RequestType | A= Return all events. C = Return current state events. |
Usage Notes
The TDWMEventStatus function provides similar functionality to an EVENT STATUS request. For more information about this interface, see EVENT STATUS.
Result Rows
| Column Name | Description |
|---|---|
| EventId | Internal ID of the Event. A value of zero indicates there is no event for this record entry and there are no events for the Normal SysCon, the Always OpEnv and a State. Events are reported in the order they appear within the associated expression. Only events in the associated expression are included. |
| EventStatus | Current status of the event. The value is either Inactive or Active. |
| EventActiveDate | Date when EventStatus was last changed. This is the date when the EventStatus was set to Inactive or Active. |
| EventActiveTime | Time when EventStatus was last changed. This is the time when EventStatus is set to Inactive or Active. |
| ExpressionId | Internal ID of the Expression. A value of zero indicates there is no expression for this record entry. There are no expressions for the Normal SysCon, the Always OpEnv, and a State. For the CURRENT state request, the first TRUE expression for the State is included. When there are multiple TRUE expressions for a state, only the first one processed is reported. The order of processing is consistent within a rule set and, therefore, the same TRUE expression is reported on every request. |
| ExpressionStatus | Current status of the Expression:
|
| ExpActiveDate | Date when ExpressionStatus last changed. |
| ExpActiveTime | Time when Expression Status was last changed. This is the time when Expression Status was set to either Active or Inactive. |
| RecordType | Type of record, for example: a SysCon, OpEnv, or Notify Only Expression. |
| RecordId | Internal ID of the SysCon or OpEnv depending on the type of record specified in the RecordType field. A value of zero indicates the Notify Only Expression record type. |
| RecordStatus | Current status of the SysCon or OpEnv record:
|
| DueToDuration | An indicator that the corresponding Syscon is being considered as TRUE or is TRUE:
This field is valid only when SysCon is the specified RecordType.
|
| StateActiveDate | Date when RecordStatus was last changed. |
| StateActiveTime | Time when RecordStatus was last changed. |
