    Connecting to a Server

    QuestDB provides a number of APIs, REST / ILP - InfluxDB Line Protocol and PostgreSQL wire protocol.
    For querying we are going to connect to the PostgreSQL on port 8812

    2. Host:localhost
      Port: 8812
    3. Database: qdb
    4. Username: admin
      Password: quest
    5. Click Add

    Sending Queries

    Copy paste the below code into the SQL editor. Then highlight the commands you want to run and press Ctrl + e to run that code. See Keyboard Shortcuts.
