Connect to Presto Data in RazorSQL

Connect to Presto from wizards and query Presto data from the GUI in the RazorSQL database management tool.

The CData JDBC Driver for Presto enables standards-based access from third-party tools, from wizards in IDEs to data management and analysis tools. This article shows how to connect to Presto using wizards in RazorSQL.

Create a JDBC Data Source for Presto Data

  1. Open the RazorSQL application and, in the Connections menu, select Add Connection Profile -> Other -> JDBC.
  2. In the Connection Wizard that appears, set the following properties:
    • Driver Location: Set this property to the path to the lib subfolder in the installation directory.
    • Driver Class: Set the driver class to cdata.jdbc.presto.PrestoDriver.
    • Username: Enter the username. (This property can also be set in the JDBC URL.)
    • Password: Enter the password. (This property can also be set in the JDBC URL.)
    • JDBC URL: Enter connection parameters. The JDBC URL begins with jdbc:presto: and is followed by a semicolon-separated list of connection properties.

      Set the Server and Port connection properties to connect, in addition to any authentication properties that may be required.

      To enable TLS/SSL, set UseSSL to true.

      Authenticating with LDAP

      In order to authenticate with LDAP, set the following connection properties:

      • AuthScheme: Set this to LDAP.
      • User: The username being authenticated with in LDAP.
      • Password: The password associated with the User you are authenticating against LDAP with.

      Authenticating with Kerberos

      In order to authenticate with KERBEROS, set the following connection properties:

      • AuthScheme: Set this to KERBEROS.
      • KerberosKDC: The Kerberos Key Distribution Center (KDC) service used to authenticate the user.
      • KerberosRealm: The Kerberos Realm used to authenticate the user with.
      • KerberosSPN: The Service Principal Name for the Kerberos Domain Controller.
      • KerberosKeytabFile: The Keytab file containing your pairs of Kerberos principals and encrypted keys.
      • User: The user who is authenticating to Kerberos.
      • Password: The password used to authenticate to Kerberos.

      Built-in Connection String Designer

      For assistance in constructing the JDBC URL, use the connection string designer built into the Presto JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

      java -jar cdata.jdbc.presto.jar

      Fill in the connection properties and copy the connection string to the clipboard.

      A typical JDBC URL is the following:

      jdbc:presto:Server=127.0.0.1;Port=8080;

Query Presto Data and Select Tables

After establishing a connection, the wizard will close and the connection will be available in the connections panel. You can then query the tables.
