How to Query Presto Data in MySQL Workbench

You can use the SQL Gateway from the ODBC Driver for Presto to query Presto data through a MySQL interface. Follow the procedure below to start the MySQL remoting service of the SQL Gateway and work with live Presto data in MySQL Workbench.

Getting Started

---

Connect to Presto Data

If you have not already done so, provide values for the required connection properties in the data source name (DSN). You can use the built-in Microsoft ODBC Data Source Administrator to configure the DSN. This is also the last step of the driver installation. See the "Getting Started" chapter in the help documentation for a guide to using the Microsoft ODBC Data Source Administrator to create and configure a DSN.

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.

Configure the SQL Gateway

See the SQL Gateway Overview to set up connectivity to Presto data as a virtual MySQL database. You will configure a MySQL remoting service that listens for MySQL requests from clients. The service can be configured in the SQL Gateway UI.

Query Presto from MySQL Workbench

The steps below outline connecting to the virtual Presto database created in the SQL Gateway from MySQL Workbench and issuing basic queries to work with live Presto data.

Connect to Presto through the SQL Gateway

1. In MySQL Workbench, click to add a new MySQL connection.
2. Name the connection (CData SQL Gateway for Presto).
3. Set the Hostname, Port, and Username parameters to connect to the SQL Gateway.
4. Click Store in Vault to set and store the password.
5. Click Test Connection to ensure the connection is configured properly and click OK.

NOTE: When we refer to Username and Password, we mean the credentials for the user(s) created for the SQL Gateway.

Query Presto Data

1. Open the connection you just created (CData SQL Gateway for Presto).
2. Click File -> New Query Tab.
3. Write a SQL query to retrieve Presto data, like SELECT * FROM `CData Presto Sys`.Customer;

With access to live Presto data from MySQL Workbench, you can easily query and update Presto, just like you would a MySQL database. Get started now with a free, 30-day trial of the CData ODBC Driver for Presto and the CData SQL Gateway.
