Oracle8i introduces the following new types:
· BLOB
· CLOB
· BFILE
The design of these types allow Oracle Objects for OLE to access them much
faster than Long or Long Raw. For this reason you should convert existing Long Raw
code to BLOB, CLOB and BFILE.
To make migration easier, the AppendChunk, AppendChunkByte, GetChunk,
GetChunkByte, GetChunkByteEx, and ReadChunk methods can be used with BLOBs, CLOBs, and
BFILEs. However, new applications should only use LOBs and BFILEs. The OraLOB
object should be used to access LOBs and BFILEs, rather than these Long Raw
chunking methods which are provided for backward compatibility only. Note that
OraLob offers maximum control.
For older applications using the Long Raw chunking methods, migration should
be relatively simple with few code changes required. The primary code changes
involve the requirement that NULL BLOBs and CLOBs be updated with "Empty" before
being used.
