매개 변수
- scanType
유형: Microsoft.SqlServer.Management.Smo.StatisticsScanType

- sampleValue
유형: System.Int32
An Int32 value that specifies the number of rows or percentage of the total number of rows to use in a sampled scan. This parameter is required only when the scanType indicates a sampled scan.
- recompute
유형: System.Boolean
