    hCol : int
) : IStream

Parameters

hRow
The row handle.

hCol
The column handle.

An IStream interface.

Remarks

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.
