Gets or sets the total amount to be read or written for multiple chunk
Write operations (polling). A value of zero means that polling is not used. This property is read/write at run time.
pollamountbytes = OraBFile.PollingAmount OraBfile.PollingAmount = pollamountbytes pollamountbytes = OraBlob.PollingAmount OraBlob.PollingAmount = pollamountbytes pollamountchars= OraClob.PollingAmount OraClob.PollingAmount = pollamountchars
This value is expressed in bytes for the
OraBFILE objects, or characters for the
OraCLOB object. It is set before beginning a multiple-chunk read or write operation. After it is set, a series of
Write operations must be issued until the LOB
Status property no longer returns
ORALOB_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 results in an error.
