# SetPollingAmount Method (not used)

Applies To

OBlob

OClob

OBfile

Description

Sets the total amount to be read or written for multiple chunk Read and Write operations (polling). A value of zero means that polling will not be used. This attribute is read/write at runtime.

Usage

void SetPollingAmount(unsigned long amount) const throw(OException)

Arguments

amount | Total amount to be read or written for multiple chunk Read and Write operations.

Remarks

This value is expressed in bytes for OBlob/OBFILE or characters for OClob. It is set prior to beginning a multiple chunk read or write operation. After it is set, a series of Read or Write operations must be issued until LOB GetStatus no longer returns OLOB_NEED_DATA .This occurs when the PollingAmount bytes or characters have been read. Attempting to do other LOB operations before the end of the polling operation will result in an error.
