Update operators for tables

Some Data API commands, like Update a row, use update operators to modify rows in a table.

Set

The $set operator sets the value of the specified column to the specified value.

To update a value to a map that includes non-string keys, you must use an array of key-value pairs to update the map column. Otherwise, you can use an array of key-value pairs or a normal map.

Example setting a non-map column:

  • Python

  • TypeScript

  • Java

  • curl

from astrapy import DataAPIClient

# Get an existing table
client = DataAPIClient("APPLICATION_TOKEN")
database = client.get_database("API_ENDPOINT")
table = database.get_table("TABLE_NAME")

# Update a row
table.update_one(
    {"title": "Hidden Shadows of the Past", "author": "John Anthony"},
    {
        "$set": {"rating": 4.5, "genres": ["Fiction", "Drama"]},
    },
)
import { DataAPIClient } from "@datastax/astra-db-ts";

// Get an existing table
const client = new DataAPIClient("APPLICATION_TOKEN");
const database = client.db("API_ENDPOINT");
const table = database.table("TABLE_NAME");

// Update a row
(async function () {
  await table.updateOne(
    {
      title: "Hidden Shadows of the Past",
      author: "John Anthony",
    },
    {
      $set: {
        rating: 4.5,
        genres: ["Fiction", "Drama"],
      },
    },
  );
})();

  public static void main(String[] args) {
    // Get an existing table
    Table<Row> table =
        new DataAPIClient("APPLICATION_TOKEN")
            .getDatabase("API_ENDPOINT")
            .getTable("TABLE_NAME");

    // Update a row
    Filter filter =
        new Filter(
            Map.of(
                "title", "Hidden Shadows of the Past",
                "author", "John Anthony"));
    TableUpdateOperation update =
        new TableUpdateOperation()
            .set("rating", 4.5)
            .set("genres", Arrays.asList("Fiction", "Drama"));
    table.updateOne(filter, update);
  }
}
curl -sS -L -X POST "API_ENDPOINT/api/json/v1/KEYSPACE_NAME/TABLE_NAME" \
  --header "Token: APPLICATION_TOKEN" \
  --header "Content-Type: application/json" \
  --data '{
  "updateOne": {
    "filter": {
      "title": "Hidden Shadows of the Past",
      "author": "John Anthony"
    },
    "update": {
      "$set": {
        "rating": 4.5,
        "genres": ["Fiction", "Drama"]
      }
    }
  }
}'

Example setting a map column:

  • Python

  • TypeScript

  • Java

  • curl

If the updated map includes non-string keys, you must use an array of key-value pairs to update the map column. With the Python client, you can also use DataAPIMap to encode maps that use non-string keys.

Otherwise, you can use an array of key-value pairs or a normal map.

from astrapy import DataAPIClient
from astrapy.data_types import DataAPIMap

# Get an existing table
client = DataAPIClient("APPLICATION_TOKEN")
database = client.get_database("API_ENDPOINT")
table = database.get_table("TABLE_NAME")

# Update a row
table.update_one(
    {"title": "Hidden Shadows of the Past", "author": "John Anthony"},
    {
        "$set": {
            # This map has non-string keys,
            # so the update is an array of key-value pairs
            "map_column_1": [[1, "value1"], [2, "value2"]],
            # Alternatively, use DataAPIMap to encode maps with non-string keys
            "map_column_2": DataAPIMap({1: "value1", 2: "value2"}),
            # This map does not have non-string keys,
            # so the update does not need to be an array of key-value pairs
            "map_column_3": {"key1": "value1", "key2": "value2"},
        }
    },
)

If the updated map includes non-string keys, you must use an array of key-value pairs to update the map column.

Otherwise, you can use an array of key-value pairs or a normal map.

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

// Get an existing table
const client = new DataAPIClient("APPLICATION_TOKEN");
const database = client.db("API_ENDPOINT");
const table = database.table("TABLE_NAME");

// Update a row
(async function () {
  await table.updateOne(
    {
      title: "Hidden Shadows of the Past",
      author: "John Anthony",
    },
    {
      $set: {
        // This map has non-string keys,
        // so the update is an array of key-value pairs
        map_column_1: [
          [1, "value1"],
          [2, "value2"],
        ],
        // This map does not have non-string keys,
        // so the update does not need to be an array of key-value pairs
        map_column_2: {
          key1: "value1",
          key2: "value2",
        },
      },
    },
  );
})();

The Java client supports updates of a row with a map column that includes non-string keys. (You don’t need to use an array of key-value pairs to represent the map column.)

public class Example {

  public static void main(String[] args) {
    // Get an existing table

        new DataAPIClient("APPLICATION_TOKEN")

            .getTable("TABLE_NAME");

    Filter filter =
        Filters.and(
            Filters.eq("title", "Hidden Shadows of the Past"),
            Filters.eq("author", "John Anthony"));

    // This map has non-string keys,
    // but the insertion can still be represented as a map
    // instead of an array of key-value pairs
    Map<Integer, String> mapColumn1 = Map.of(1, "value1", 2, "value2");

    // This map does not have non-string keys
    Map<String, String> mapColumn2 = Map.of("key1", "value1", "key2", "value2");

    TableUpdateOperation update =
        new TableUpdateOperation().set("map_column_1", mapColumn1).set("map_column_2", mapColumn2);

    table.updateOne(filter, update);
  }
}

If the updated map includes non-string keys, you must use an array of key-value pairs to update the map column.

Otherwise, you can use an array of key-value pairs or a normal map.

curl -sS -L -X POST "API_ENDPOINT/api/json/v1/KEYSPACE_NAME/TABLE_NAME" \
  --header "Token: APPLICATION_TOKEN" \
  --header "Content-Type: application/json" \
  --data '{
  "updateOne": {
    "filter": {
      "title": "Hidden Shadows of the Past",
      "author": "John Anthony"
    },
    "update": {
      "$set": {
        # This map has non-string keys,
        # so the update is an array of key-value pairs
        "map_column_1": [
            [1, "value1"],
            [2, "value2"]
        ],
        # This map does not have non-string keys,
        # so the update does not need to be an array of key-value pairs
        "map_column_2": {
          "key1": "value1",
          "key2": "value2"
        }
      }
    }
  }
}'

Unset

The $unset operator sets the specified column’s value to null or the equivalent empty form, such as [] or {} for map, list, and set types.

Unsetting a column will produce a tombstone. Excessive tombstones can impact query performance. For more information, see What are tombstones.

        "$unset": {
            "genres": ""
        }
    }
  }
}'

Push

The $push operator appends a single element to a map, list, or set.

To append multiple items, use the $each operator with $push.

When appending to a map, if the appended key-value pair has a non-string key, you must represent the key-value pair as an array. Otherwise, you can either use an array or a normal map.

Example appending to a list or set column:

  • Python

  • TypeScript

  • Java

  • curl

from astrapy import DataAPIClient

# Get an existing table
client = DataAPIClient("APPLICATION_TOKEN")
database = client.get_database("API_ENDPOINT")

Each

The $each operator modifies the $push operator to append multiple items to a map, list, or set.

Example appending to a list or set column:

  • Python

  • TypeScript

  • Java

  • curl

from astrapy import DataAPIClient

# Get an existing table
client = DataAPIClient("APPLICATION_TOKEN")
database = client.get_database("API_ENDPOINT")
table = database.get_table("TABLE_NAME")

# Update a row
table.update_one(
    {"title": "Hidden Shadows of the Past", "author": "John Anthony"},
    {
        "$push": {
            # Appends a single element to the "genres" list
            "genres": "SciFi",
            # Appends two elements to the "topics" list
            "topics": {"$each": ["robots", "AI"]},
        }
    },
