Instantiates and initializes the CDynamicAccessor object.
Syntax
CDynamicAccessor(
DBBLOBHANDLINGENUM eBlobHandling = DBBLOBHANDLING_DEFAULT,
DBLENGTH nBlobSize = 8000
);
Parameters
eBlobHandling
Specifies how the binary large object (BLOB) data is to be handled. The default value is DBBLOBHANDLING_DEFAULT. See SetBlobHandling for a description of the DBBLOBHANDLINGENUM values.
nBlobSize
The maximum BLOB size in bytes; column data over this value is treated as a BLOB. The default value is 8,000. See SetBlobSizeLimit for details.
Remarks
If you use the constructor to initialize the CDynamicAccessor object, you can specify how it will bind BLOBs. BLOBs can contain binary data such as graphics, sound, or compiled code. The default behavior is to treat columns more than 8,000 bytes as BLOBs and try to bind them to an ISequentialStream object. However, you can specify a different value to be the BLOB size.
You can also specify how CDynamicAccessor handles column data that qualifies as BLOB data: it can handle BLOB data in the default manner; it can skip (does not bind) BLOB data; or it can bind BLOB data in provider-allocated memory.
