程序集：  Microsoft.SqlServer.DTSPipelineWrap（在 Microsoft.SqlServer.DTSPipelineWrap.dll 中）

语法

声明
Sub GetStatus ( _
    hRow As Integer, _
    hCol As Integer, _
    <OutAttribute> ByRef pDBStatus As UInteger _
)
用法
Dim instance As IDTSBuffer100
Dim hRow As Integer
Dim hCol As Integer
Dim pDBStatus As UInteger

instance.GetStatus(hRow, hCol, pDBStatus)

void GetStatus(
    int hRow,
    int hCol,
    out uint pDBStatus
)

void GetStatus(
    [InAttribute] int hRow, 
    [InAttribute] int hCol, 
    [OutAttribute] unsigned int% pDBStatus
)

abstract GetStatus : 
        hRow:int * 
        hCol:int * 
        pDBStatus:uint32 byref -> unit 

function GetStatus(
    hRow : int, 
    hCol : int, 
    pDBStatus : uint
)

参数

• hRow
  类型：System. . :: . .Int32
  The handle to the row.

• hCol
  类型：System. . :: . .Int32
  The handle to the column.

• pDBStatus
  类型：System. . :: . .UInt32%
  The status value of the column.

注释

This method retrieves the OLE DB status information for the specified column. If the IDTSBuffer100 was not created with the BUFF_NOOLEDB flag, the status is either DTPSTATUS_ISNULL or DTPSTATUS_OK. Otherwise, the status stored at the lStatusOffset location in the column is returned. The value is the sum of the values contained in the DTPSTATUSENUM enumeration.

OLE DB may return status values that Integration Services does not recognize and disregards. Custom components should use the GetStatus method only to check for null values.
