PollingAmount (OraLOB/BFILE) Property

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.
