Syntax

'Declaration
Public Sub UpdateStatistics ( _
    scanType As StatisticsScanType, _
    sampleValue As Integer, _
    recompute As Boolean _
)
'Usage
Dim instance As Column
Dim scanType As StatisticsScanType
Dim sampleValue As Integer
Dim recompute As Boolean

instance.UpdateStatistics(scanType, sampleValue, _
    recompute)

public void UpdateStatistics(
    StatisticsScanType scanType,
    int sampleValue,
    bool recompute
)

public:
void UpdateStatistics(
    StatisticsScanType scanType, 
    int sampleValue, 
    bool recompute
)

member UpdateStatistics : 
        scanType:StatisticsScanType * 
        sampleValue:int * 
        recompute:bool -> unit 

public function UpdateStatistics(
    scanType : StatisticsScanType, 
    sampleValue : int, 
    recompute : boolean
)

Parameter

  • sampleValue
    Typ: 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
    Typ: System. . :: . .Boolean
    A Boolean value that specifies whether the statistics will be automatically recomputed or not.
    If True, the statistics are automatically recomputed. Otherwise, False.
