* NdbTransaction::execute can sometimes indicate an error
* (return with -1) while the error code on the NdbTransaction is 0.
* This is an indication that one of the operations found a record
* problem. The transaction is still ok and can continue as usual.
* The NdbTransaction::execute returns -1 together with error code
* on NdbTransaction object equal to 0 always means that an
* operation was not successful but that the total transaction was OK.
* By checking error codes on the individual operations it is possible
* to find out which operation was not successful.
*
* NdbTransaction::executeScan is used to setup a scan in the NDB kernel
* after it has been defined.
* NdbTransaction::nextScanResult is used to iterate through the
* scanned tuples.
* After each call to NdbTransaction::nextScanResult, the pointers
* of NdbRecAttr objects defined in the NdbOperation::getValue
* operations are updated with the values of the new the scanned tuple.
