  -Comparing the value of the _update_ event to the _create_ (insert) event, notice the following differences in the `payload` section:
  -
  -* The `op` field value is now `u`, signifying that this row changed because of an update
  -* The `before` field now has the state of the row with the values before the database commit
  -* The `after` field now has the updated state of the row, and here was can see that the `EMAIL` value is now `anne@example.com`.
  -* The `source` field structure has the same fields as before, but the values are different since this event is from a different position in the redo log.
  -* The `ts_ms` shows the timestamp that {prodname} processed this event.
  +The payload has the same structure as the payload of a _create_ (insert) event, but the following values are different:
  +
  +* The value of the `op` field is `u`, signifying that this row changed because of an update.
  +* The `before` field shows the former state of the row with the values that were present before the `update` database commit.
  +* The `after` field shows the updated state of the row, with the `EMAIL` value now set to `anne@example.com`.
  +* The structure of the `source` field includes the same fields as before, but the values are different, because the connector captured the event from a different position in the redo log.
  +* The `ts_ms` field shows the timestamp that indicates when {prodname} processed the event.
   
   The `payload` section reveals several other useful pieces of information.
   For example, by comparing the `before` and `after` structures, we can determine how a row changed as the result of a commit.
  
positive.code:

  |`type`
  a|Describes the kind of change. The value is one of the following:
  
  `CREATE`:: Table created.
  `ALTER`:: Table modified.
  
negative.code: Without these grants, the connector cannot operate.
