Issue 373 was created to refactor the logic into the clients. The logic in HqlParse.h is basically finding the non-inclusive end_row by adding 1 to the last non-0xff byte.
The logic is non-trivial and should not be in HqlParser.h in the first place. On Wed, Jan 20, 2010 at 10:20 AM, Stanislav Yudin <[email protected]> wrote: > Thanks Sanjit, but this is not a solution.
