class NdbError& NdbScanFilter::getNdbError | ( | ) | const |
Get filter level error.
Most errors are set only on operation level, and they abort the transaction. The error FilterTooLarge is set on filter level and by default it propagates to operation level and also aborts the transaction.
If option abort_on_too_large is set to false, then FilterTooLarge does not propagate. One can then either ignore this error (in which case no filtering is done) or try to define a new filter immediately.
