#### 23.6.14.37 The ndbinfo hash\_maps Table

[]()

* `id`

   The hash map's unique ID

* `version`

   Hash map version (integer)

* `state`

   Hash map state; see [Object::State](https://dev.mysql.com/doc/ndbapi/en/ndb-object.html#ndb-object-state) for values and descriptions.

* `fq_name`

   The hash map's fully qualified name

 The `hash_maps` table is actually a view consisting of the four columns having the same names of the [`dict_obj_info`](mysql-cluster-ndbinfo-dict-obj-info.html) table, as shown here:

```
CREATE VIEW hash_maps AS
  SELECT id, version, state, fq_name
  FROM dict_obj_info
  WHERE type=24;  # Hash map; defined in dict_obj_types
```

 See the description of [`dict_obj_info`](mysql-cluster-ndbinfo-dict-obj-info.html) for more information.

 The `hash_maps` table was added in NDB 8.0.29.
