> If you want to set a scan from your application to scan for a specific row
> prefix this is actually quite hard.
> As described in several places you can set the startRow to the prefix; yet
> the stopRow should be set to the prefix '+1'
> If the prefix 'ASCII' put into a byte[] then this is easy because you can
> simply increment the last byte of the array.
> But if your application uses real binary rowids you may run into the scenario
> that your prefix is something like
> {code}{ 0x12, 0x23, 0xFF, 0xFF }{code} Then the increment should be {code}{
> 0x12, 0x24 }{code}
> I have prepared a proposed patch that makes setting these values correctly a
> lot easier.
