FrequencyInterval Property
后续版本的 Microsoft SQL Server 将删除该功能。请避免在新的开发工作中使用该功能，并着手修改当前还在使用该功能的应用程序。
The FrequencyInterval property defines the most significant portion of a Microsoft SQL Server schedule for daily, weekly, or monthly schedules.
语法

Settings
FrequencyInterval is always interpreted relative to the value of the FrequencyType property. For some FrequencyType values, FrequencyInterval is a bit-packed long integer. FrequencyInterval is interpreted using these values.
| FrequencyType value | FrequencyInterval value |
|---|---|
SQLDMOFreq_Daily |
A positive, long integer that represents a number of day units. For example, if FrequencyInterval is 3, the scheduled activity occurs every third day. |
SQLDMOFreq_Weekly |
A bit-packed long integer. Values are interpreted using SQLDMO_WEEKDAY_TYPE, which names the days of the week. Combine values using an OR logical operator to set more than a single day. For example, combine SQLDMOWeek_Tuesday and SQLDMOWeek_Friday to schedule an activity for Tuesday and Friday. |
SQLDMOFreq_Monthly |
A positive, long integer that represents the ordinal day of the month on which the schedule is active. For example, 4 specifies the fourth day of the month. |
SQLDMOFreq_/MonthlyRelative |
A positive, long integer that represents a day of the week or a generic indication of a day. Values are interpreted using SQLDMO_MONTHDAY_TYPE. |
备注
The FrequencyInterval property is valid for Schedule objects with a FrequencyType value of SQLDMOFreq_Daily, SQLDMOFreq_Weekly, SQLDMOFreq_Monthly, or SQLDMOFreq_MonthlyRelative.
