ChangeSet
  1.1979 05/11/19 19:00:02 konstantin@stripped +1 -0
  A fix for Bug#14845 "mysql_stmt_fetch returns MYSQL_NO_DATA when 
  COUNT(*) is 0" (the test case has been pushed already)

  sql/sql_cursor.cc
    1.4 05/11/19 18:59:56 konstantin@stripped +1 -2
    Fix a return of an unitialized variable: return_zero_rows
    checks the return value of send_fields and in case it's 1
    doesn't call send_data. This caused creation of an empty result 
    set for the case when there is a cursor against a select with a 
    group function and no matching rows.

# 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.
