Description
Enable streaming on LOB operations.
Usage
void EnableStreaming(unsigned long totalamount, unsigned long initialoffset = 1) const throw(OException)
Arguments
totalamount
The total amount to be read or written for multiple chunk read and write operations (in streaming mode).
initialoffset
The offset into the LOB that reading or writing will begin with. The default
value is 1.
Remarks
Streaming mode provides the best possible performance and allows you to use a
small buffer for read and write methods. Read and write operations will stream data starting at initialoffset until totalamount has been read or written. Read and write operations must be repeatedly called
until the read or write is complete, meaning that the streaming may not be
aborted.
