If the mode of the batch operation is one of CTBATCH_GET, CTBATCH_RANGE or CTBATCH_PHYS then it may be necessary to retrieve all records that match the batch criteria. The records are retrieved by calling the CTRecord::NextBatch() method.
CTRecordNextBatch() retrieves record data from the batch buffer maintained by c-treeDB’s record handle. After a successful call to CTRecordNextBatch() the field data can be retrieved by calling the appropriate CTRecord::GetFieldAs...() functions.
Example
try
{
// retrieve records
while (CTRecord::NextBatch())
{
CTString invoice = hRecord.GetFieldAsString("Invoice");
CTString item = hRecord.GetFieldAsString("ItemNbr");
printf("%-11s %s\n", invoice.c_str(), item.c_str());
}
catch (CTException &err)
{
printf("Batch operation failed with error %d\n", err.GetErrorCode());
}
