  - ### getSql

    public String getSql()
    Description copied from interface: `BatchTranslator`
    Returns SQL String that can be used to init a PreparedStatement.
    Specified by:
      `getSql` in interface `BatchTranslator`

  - ### isNullAttribute

    protected boolean isNullAttribute(DbAttribute attribute)
    Specified by:
      `isNullAttribute` in class `BaseBatchTranslator<DeleteBatchQuery>`

  - ### updateBindings

    public DbAttributeBinding[] updateBindings(BatchQueryRow row)
    Description copied from interface: `BatchTranslator`
    Updates internal bindings to be used with a given row, returning updated bindings array. This method guarantees that the returned array contains the same bindings in the same order as in the array returned from `BatchTranslator.getBindings()` (but in a state corresponding to the 'row' parameter). Usually the returned array is actually the same object reused for every iteration, only with changed object state.
    Specified by:
      `updateBindings` in interface `BatchTranslator`

  - ### updateBinding

    protected int updateBinding(Object value, int position)
