      Description

      When executing a batch of UPDATE/DELETE statements using PreparedStatement.executeBatch(), there is no method that returns update counts.
      1) PreparedStatement.executeBatch() returns int[], but all values are -2 (meaning SUCCESS but not the real number of updated/deleted records)
      to get at least the total number of updated/deleted records, one can call:
      2) PreparedStatement.getUpdateCount() - returns -1
      3) PreparedStatement.getLargeUpdateCount() - returns -1
      Note that the same method (getLargeUpdateCount) returns the correct value with driver 2.1.0, which is our current workaround.
      Therefore we cannot upgrade the driver due to this bug!
