Settings
Constant |
Value |
Description |
|---|---|---|
SQLDMOFreq_Autostart |
64 |
The scheduled activity is started when the SQL Server Agent service starts. |
SQLDMOFreq_Daily |
4 |
The schedule is evaluated daily. |
SQLDMOFreq_Monthly |
16 |
The schedule is evaluated monthly. |
SQLDMOFreq_MonthlyRelative |
32 |
The schedule is evaluated relative to a part of a month, such as the second week. |
SQLDMOFreq_OneTime |
1 |
The scheduled activity occurs once, at a scheduled time or event. |
SQLDMOFreq_OnIdle |
128 |
The SQL Server Agent service schedules the activity for any time during which the processor is idle. |
SQLDMOFreq_Unknown |
0 |
Schedule frequency is not set, or frequency is not applicable. |
SQLDMOFreq_Valid |
255 |
A mask to test schedule frequency validity. |
SQLDMOFreq_Weekly |

Notes
Setting FrequencyType may require setting other property values to schedule an activity accurately. For example, setting FrequencyType to SQLDMOFreq_Weekly without setting the FrequencyInterval property to specify days of the week results in an unscheduled activity.
