Assembly:  Microsoft.SqlServer.DTSPipelineWrap (in Microsoft.SqlServer.DTSPipelineWrap.dll)

Syntax

'Declaration
Function GetBLOBStream ( _

'Usage
Dim instance As IDTSBuffer100

    [InAttribute] int hRow, 
    [InAttribute] int hCol
)

abstract GetBLOBStream : 
        hRow:int * 
        hCol:int -> IStream

function GetBLOBStream(
    hRow : int, 
    hCol : int
) : IStream

Parameter

• hRow
  Typ: System.Int32
  The row handle.

• hCol
  Typ: System.Int32
  The column handle.

Rückgabewert

Typ: Microsoft.SqlServer.Dts.Runtime.Wrapper.IStream
An IStream interface.

Hinweise

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.
