      Deprecated.

    - #### getSql

          public String getSql()

      Deprecated.
      Translates BatchQuery into an SQL string formatted to use in a PreparedStatement.
      Specified by:
        `getSql` in interface `BatchTranslator`

    - #### getBindings

          public DbAttributeBinding[] getBindings()

      Deprecated.
      Description copied from interface: `BatchTranslator`
      Returns the widest possible array of bindings for this query.
      Specified by:
        `getBindings` in interface `BatchTranslator`

    - #### updateBindings

          public DbAttributeBinding[] updateBindings​(BatchQueryRow row)

      Deprecated.
      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`

          protected abstract String createSql()

      Deprecated.

    - #### createBindings

          protected abstract DbAttributeBinding[] createBindings()

      Deprecated.

    - #### doUpdateBindings

          protected abstract DbAttributeBinding[] doUpdateBindings​(BatchQueryRow row)

      Deprecated.

                                           DbAttribute dbAttribute)

      Deprecated.
      Appends the name of the column to the query buffer. Subclasses use this method to append column names in the WHERE clause, i.e. for the columns that are not being updated.
