Applies To
OraBLOB, OraCLOB
OraBFILE
Description
Gets or 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 property is read/write at runtime.
Usage
pollamountbytes = OraBFile.PollingAmount
OraBfile.PollingAmount = pollamountbytes
pollamountbytes = OraBlob.PollingAmount
OraBlob.PollingAmount = pollamountbytes
pollamountchars= OraClob.PollingAmount
OraClob.PollingAmount = pollamountchars
Remarks
This value is expressed in bytes for OraBlob/OraBFILE or characters for
OraClob. 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 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 will result in an error.
