How can I query all tables for the current user in Couchbase?

Couchbase is a document-oriented NoSQL database that does not directly support the concept of tables. Instead, it organizes data using the concepts of collections and buckets.

To retrieve all collections of the current user, you can use Couchbase’s query language N1QL (similar to SQL). Here is one possible method:

  1. Log in to the Couchbase console with administrator privileges.
  2. Navigate to the Buckets tab in the console and locate the bucket you are interested in.
  3. Click on the name of the bucket to open up its detailed information on the right side.
  4. In the detailed information page, you will find a list of collections in this bucket.

Please note that Couchbase also supports querying information about collections and buckets using SDKs or command-line tools. You can use Couchbase’s Java, Node.js, Python, etc. SDKs to write custom applications to query information about collections and buckets. For example, using the Java SDK, you can use the following code to query all collections:

import com.couchbase.client.java.Cluster;
import com.couchbase.client.java.Collection;
import com.couchbase.client.java.json.JsonObject;

public class Main {
    public static void main(String[] args) {
        Cluster cluster = Cluster.connect("127.0.0.1", "username", "password");
        Collection collection = cluster.bucket("bucketName").defaultCollection();
        
        JsonObject queryResult = collection.query("SELECT name FROM system:namespaces");
        System.out.println(queryResult);
        
        cluster.disconnect();
    }
}

Please note that the above code is for demonstration purposes only and assumes you have already installed the Couchbase Java SDK and properly configured the connection parameters. You will need to replace “bucketName” with the name of the bucket you are interested in.
