query

  • query(
        query: string,
        database?: string,
        queryOptions?: Partial<QueryOptions>,
    ): AsyncGenerator<Record<string, any>, void, void>

  • Execute a query and return the results as an async generator.

    Parameters

    • query: string

      The query string.

    • Optionaldatabase: string

      The name of the database to query.

    • queryOptions: Partial<QueryOptions> = ...

      The options for the query (default: { type: 'sql' }).

    Returns AsyncGenerator<Record<string, any>, void, void>

    An async generator that yields maps of string keys to any values.

    Example

       client.query('SELECT * from net', 'traffic_db', {
          type: 'sql',
          headers: {
            'channel-pref': 'eu-west-7',
            'notify': 'central',
          },
        })

queryPoints

  • queryPoints(
        query: string,
        database?: string,
        queryOptions?: Partial<QueryOptions>,
    ): AsyncGenerator<PointValues, void, void>

  • Execute a query and return the results as an async generator.

    Parameters

    • query: string

      The query string.

    • Optionaldatabase: string

      The name of the database to query.

    • queryOptions: Partial<QueryOptions> = ...

      The type of query (default: {type: 'sql'}).

    Returns AsyncGenerator<PointValues, void, void>

    An async generator that yields PointValues object.

    Example

    client.queryPoints('SELECT * FROM cpu', 'performance_db', {
          type: 'sql',
