매개 변수
- affectType
유형: Microsoft.SqlServer.Management.Smo.StatisticsTarget
A StatisticsTarget object value that specifies the target of the statistics update, such as columns or indexes.
- scanType
유형: Microsoft.SqlServer.Management.Smo.StatisticsScanType
A StatisticsScanType object value that specifies the way in which statistical information is gathered.
- sampleValue
유형: System.Int32
An Int32 value that specifies the sample size. The units are dependent on the scan type.
- recompute
유형: System.Boolean
A Boolean value that specifies whether to recompute the statistics.If True, the statistics are recomputed.If False, the statistics are not recomputed.
