  Bug#24568, NdbScanFilter NAND/NOR operations sometimes do not works as expected
  this patch is an absolutely necessary supplement of the previous patch,
  the previous patch doesnot cover isnull() and isnotnull() methods' effect.

  ndb/src/ndbapi/NdbScanFilter.cpp@stripped, 2007-03-21 15:36:20+08:00, Justin.He@stripped +8 -2
    correct isnull() and isnotnull() when these two methods called in a NAND/NOR operation 

# This is a BitKeeper patch.  What follows are the unified diffs for the
# set of deltas contained in the patch.  The rest of the patch, the part
# that BitKeeper cares about, is below these diffs.
