Use the list_type_names method, which belongs to the astrapy.Database class.

Method signature

list_type_names(
  *,
  keyspace: str,
  table_admin_timeout_ms: int,
  request_timeout_ms: int,
  timeout_ms: int,
) -> list[str]

Name Type Summary

Name	Type	Summary
`keyspace`	`str`	Optional. The keyspace to inspect. Default: The database’s working keyspace.
`table_admin_timeout_ms`	`int`	A timeout, in milliseconds, for the underlying HTTP request. If not provided, the `Database` setting is used. This parameter is aliased as `request_timeout_ms` and `timeout_ms` for convenience.

keyspace

str

Optional. The keyspace to inspect.

Default: The database’s working keyspace.

table_admin_timeout_ms

int

A timeout, in milliseconds, for the underlying HTTP request. If not provided, the Database setting is used. This parameter is aliased as request_timeout_ms and timeout_ms for convenience.

Use the listTypes method, which belongs to the Db class.

Method signature

async listTypes(
  options?: {
    nameOnly: true,
    keyspace?: string,
    timeout?: number | TimeoutDescriptor,
  },
): string[]

Name Type Summary

Name	Type	Summary
`options`	`ListTypesOptions`	Optional. The options for this operation. See Properties of `options` for more details.

options

ListTypesOptions

Optional. The options for this operation. See Properties of options for more details.

Properties of `options`
Name	Type	Summary
`nameOnly`	`false`	Optional. Must be `true` to return only the user defined type names. Otherwise, additional metadata about the user defined types is returned.
`keyspace`	`string`	Optional. The keyspace to inspect. Default: The database’s working keyspace.
`timeout`	`number` \| `TimeoutDescriptor`	Optional. A timeout to impose on the underlying API request.

Use the listTypeNames method, which belongs to the com.datastax.astra.client.databases.Database class.

Method signature

List<String> listTypeNames()

List<String> listTypes(ListTypesOptions options)

Name Type Summary

Name	Type	Summary
`options`	`ListTypesOptions`	Optional. The options for this operation, including the keyspace and timeouts.

options

ListTypesOptions

Optional. The options for this operation, including the keyspace and timeouts.

Use the ListTypeNamesAsync method, which belongs to the Database class. You can also use ListTypeNames, which is the synchronous version of the method.

Method signature

public Task<IEnumerable<string>> ListTypeNamesAsync(
  ListTypeNamesOptions options = null
);

Name Type Summary

Name	Type	Summary
`options`	`ListTypeNamesOptions`	Optional. General API options for this operation, including the keyspace and timeout. For more information and examples, see Customize API interaction.

options

ListTypeNamesOptions

Optional. General API options for this operation, including the keyspace and timeout. For more information and examples, see Customize API interaction.

Use the listTypes command.

Command signature

curl -sS -L -X POST "API_ENDPOINT/api/json/v1/KEYSPACE_NAME" \
--header "Token: APPLICATION_TOKEN" \
--header "Content-Type: application/json" \
--data '{
  "listTypes": {
    "options": {
      "explain": false
    }
  }
}'

Name Type Summary

Name	Type	Summary
`options.explain`	`false`	Must be `false` to return only the names of the user-defined types. Otherwise, additional metadata about the user-defined types is returned.

options.explain

false

Must be false to return only the names of the user-defined types. Otherwise, additional metadata about the user-defined types is returned.

Examples

The following examples demonstrate how to list names of the user-defined types in a keyspace.

Python
TypeScript
Java
C#
curl

from astrapy import DataAPIClient

# Get a database
client = DataAPIClient()
database = client.get_database(
    "API_ENDPOINT", token="APPLICATION_TOKEN"
)

# List type names
result = database.list_type_names()
print(result)

import { DataAPIClient } from "@datastax/astra-db-ts";

// Get a database
const client = new DataAPIClient();
const database = client.db("API_ENDPOINT", {
  token: "APPLICATION_TOKEN",
});

// List type names
(async function () {
  const result = await database.listTypes({ nameOnly: true });

  console.log(result);
})();

import com.datastax.astra.client.DataAPIClient;
import com.datastax.astra.client.databases.Database;
import java.util.List;

public class Example {

  public static void main(String[] args) {
    // Get a database
    Database database = new DataAPIClient("APPLICATION_TOKEN").getDatabase("API_ENDPOINT");

    // List type names
    List<String> result = database.listTypeNames();

    System.out.println(result);
  }
}

using System.Text.Json;
using DataStax.AstraDB.DataApi;

namespace Examples;

public class Program
{
  static async Task Main()
  {
    // Get an existing table
    var client = new DataAPIClient();
    var database = client.GetDatabase(
      "API_ENDPOINT",
      "APPLICATION_TOKEN"
    );

    // List type names
    var names = await database.ListTypeNamesAsync();

    Console.WriteLine(JsonSerializer.Serialize(names));
  }
}
