Обсуждение: snapshot - src: Since oracle does return '0' for rowcount, even when

Log Message:
-----------
Since oracle does return '0' for rowcount, even when there is more than zero rows returned, it broke the code.
Now there is a workaround based only on fetchrow_array behaviour (returning undef or error when there is no more
recordsto retrieve) and the count of records retrieved with the current fetch.
