声明
Function GetBLOBStream ( _
hRow As Integer, _
hCol As Integer _
) As IStream
用法
Dim instance As IDTSBuffer100
Dim hRow As Integer
Dim hCol As Integer
Dim returnValue As IStream
returnValue = instance.GetBLOBStream(hRow, _
hCol)
IStream GetBLOBStream(
int hRow,
int hCol

hRow:int *
hCol:int -> IStream
function GetBLOBStream(
hRow : int,
hCol : int
) : IStream
参数
- hRow
类型：System.Int32
The row handle.
- hCol
类型：System.Int32
The column handle.
返回值
类型：Microsoft.SqlServer.Dts.Runtime.Wrapper.IStream

注释
This method is used to retrieve an IStream interface that can be used to read and write the data bytes in a binary large object (BLOB). When the IStream is finished manipulating the data using the stream, it can be inserted back into the column using the SetBLOBFromStream method.
