Examples
The following examples demonstrate how to list table metadata.
List table metadata
using System.Text.Json;
using DataStax.AstraDB.DataApi;
namespace Examples;
public class Program
{
static async Task Main()
{
// Get a database
var client = new DataAPIClient();
var database = client.GetDatabase(
"API_ENDPOINT",
"APPLICATION_TOKEN"
);
// List table metadata
var result = await database.ListTablesAsync();
Console.WriteLine(JsonSerializer.Serialize(result));
}
}List table metadata and specify the keyspace
By default, this method uses the working keyspace of your database. If you want to use a different keyspace, you must specify the keyspace.
using System.Text.Json;
using DataStax.AstraDB.DataApi;
using DataStax.AstraDB.DataApi.Core;
namespace Examples;
public class Program
{
static async Task Main()
{
// Get a database
var client = new DataAPIClient();
var database = client.GetDatabase(
"API_ENDPOINT",
"APPLICATION_TOKEN"
);
// List table metadata
var result = await database.ListTablesAsync(
new ListTablesOptions() { Keyspace = "KEYSPACE_NAME" }
);
Console.WriteLine(JsonSerializer.Serialize(result));
}
