Attributes

Remarks

The IDTSBLOBObject100 provides support for reading and writing bytes in a binary large object (BLOB). The bytes added to the object are stored in memory until the SpoolThreshold property is reached, and then are written to a temporary file.

Managed component developers do not use this object but instead use the BlobColumn class.

Properties

Length

Gets the number of bytes stored in an IDTSBLOBObject100.

SpoolThreshold

Gets or sets the number of bytes to store in memory before writing to a temporary file.

Methods

AddData(Byte, UInt32)

Adds bytes to an IDTSBLOBObject100 object.

GetData(UInt32, Byte, UInt32, UInt32)

Retrieves the specified number of bytes from an IDTSBLOBObject100 object.

GetStream()

Gets an IStream object that can be used to read or write bytes in an IDTSBLOBObject100.

PutData(UInt32, Byte, UInt32, UInt32)

Adds bytes in a specific location in the IDTSBLOBObject100

ResetData()

Empties the bytes stored by an IDTSBLOBObject100.

SetFromStream(ISequentialStream)

Adds bytes to an IDTSBLOBObject100 from an ISequentialStream object.
