How to connect to SingleStore Data with Squirrel SQL client



Connect to SingleStore data and execute queries in the Squirrel SQL Client.

The CData JDBC Driver for SingleStore enables you to execute queries to SingleStore data in tools like Squirrel SQL Client. In this article, you will create a JDBC data source for SingleStore data and execute queries.

Add the JDBC Driver for SingleStore

Follow the steps below to add the driver JAR.

  1. In Squirrel SQL, click Windows -> View Drivers.
  2. Click the plus icon to open the Add Driver wizard.
  3. In the Name box, enter a user-friendly name for the driver; for example, CData JDBC Driver for SingleStore.
  4. In the Example URL box, enter jdbc:singlestore:
  5. In the Extra Class Path tab, click Add.
  6. In the file explorer dialog that opens, select the JAR file for the driver, located in the lib subfolder of the installation directory.
  7. Click List Drivers to populate the Class Name menu with the class name for the driver, cdata.jdbc.singlestore.SingleStoreDriver.

Define Connection Properties

Follow the steps below to save connection properties in the driver alias.

  1. Click Windows -> View Aliases.
  2. In the pane that lists the aliases, click the plus icon.
  3. In the Add Alias wizard that opens, the following fields are required for the JDBC driver:

    • Name: Enter a name for the alias; for example, CData SingleStore Source.
    • Driver: Select the CData JDBC Driver for SingleStore.
    • URL: Enter jdbc:singlestore:
  4. If you want to define any additional properties, click Properties.
  5. In the Driver properties tab of the dialog that appears, select the Use driver properties checkbox.
  6. In the Specify column, select the checkboxes for the required connection properties.

    The following connection properties are required in order to connect to data.

    • Server: The host name or IP of the server hosting the SingleStore database.
    • Port: The port of the server hosting the SingleStore database.
    • Database (Optional): The default database to connect to when connecting to the SingleStore Server. If this is not set, tables from all databases will be returned.

    Connect Using Standard Authentication

    To authenticate using standard authentication, set the following:

    • User: The user which will be used to authenticate with the SingleStore server.
    • Password: The password which will be used to authenticate with the SingleStore server.

    Connect Using Integrated Security

    As an alternative to providing the standard username and password, you can set IntegratedSecurity to True to authenticate trusted users to the server via Windows Authentication.

    Connect Using SSL Authentication

    You can leverage SSL authentication to connect to SingleStore data via a secure session. Configure the following connection properties to connect to data:

    • SSLClientCert: Set this to the name of the certificate store for the client certificate. Used in the case of 2-way SSL, where truststore and keystore are kept on both the client and server machines.
    • SSLClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
    • SSLClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
    • SSLClientCertType: The certificate type of the client store.
    • SSLServerCert: The certificate to be accepted from the server.

    Connect Using SSH Authentication

    Using SSH, you can securely login to a remote machine. To access SingleStore data via SSH, configure the following connection properties:

    • SSHClientCert: Set this to the name of the certificate store for the client certificate.
    • SSHClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
    • SSHClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
    • SSHClientCertType: The certificate type of the client store.
    • SSHPassword: The password that you use to authenticate with the SSH server.
    • SSHPort: The port used for SSH operations.
    • SSHServer: The SSH authentication server you are trying to authenticate against.
    • SSHServerFingerPrint: The SSH Server fingerprint used for verification of the host you are connecting to.
    • SSHUser: Set this to the username that you use to authenticate with the SSH server.

    Below is a typical connection string:

    jdbc:singlestore:User=myUser;Password=myPassword;Database=NorthWind;Server=myServer;Port=3306;
  7. In the dialog that appears after you click OK, click connect to test the connection.

Discover Schemas and Query SingleStore Data

After the metadata has loaded, a new tab for the SingleStore data source is displayed. On the Objects subtab, you can discover schema information, such as the available tables and views.

To view table data, select the table on the Objects tab. The table data is then loaded in a grid on the Content tab.

To execute an SQL query, enter the query on the SQL tab and then click Run SQL (the runner icon). For example:

SELECT ShipName, ShipCity FROM Orders WHERE ShipCountry = 'USA'
