How to connect to SingleStore Data in DBVisualizer

The CData JDBC Driver for SingleStore implements JDBC standards to provide connectivity to SingleStore data in applications ranging from business intelligence tools to IDEs. This article shows how to establish a connection to SingleStore data in DBVisualizer and use the table editor to edit and save SingleStore data.

Create a New Driver Definition for SingleStore Data

Follow the steps below to use the Driver Manager to provide connectivity to SingleStore data from DBVisualizer tools.

1. In DBVisualizer, click Tools -> Driver Manager.
2. Click the plus sign "" to create a new driver.
3. Select "Custom" as the template.
4. On the Driver Settings tab:
   • Set Name to a user-friendly name (e.g. "CData SingleStore Driver")
   • Set URL Format to jdbc:singlestore:
   • In Driver artifacts and jar files (jars are loaded in order from top):
     1. Click the plus sign "" -> "Add Files"
     2. Navigate to the "lib" folder in the installation directory (C:\Program Files\CData[product_name] XXXX\)
     3. Select the JAR file (cdata.jdbc.SingleStore.jar) and click "Open"
5. The Driver Class should populate automatically. If not, select class (cdata.jdbc.singlestore.SingleStoreDriver).

Define the Connection to the JDBC Data Source

Close the "Driver Manager" and follow the steps below to save connection properties in the JDBC URL.

1. In the "Databases" tab, click the plus sign "" and select the driver you just created.

2. In the "Connection" section, set the following options:

   • Database Type: If you selected the wizard option, the database type is automatically detected. If you selected the "No Wizard" option, select the Generic or Auto Detect option in the Database Type menu.
   • Driver Type: Select the driver you just created.

   • Database URL: Enter the full JDBC URL. The syntax of the JDBC URL is jdbc:singlestore: followed by the connection properties in a semicolon-separated list of name-value pairs.

     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.

     Built-in Connection String Designer

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

     java -jar cdata.jdbc.singlestore.jar

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

     When you configure the JDBC URL, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

     A typical connection string is below:

     jdbc:singlestore:User=myUser;Password=myPassword;Database=NorthWind;Server=myServer;Port=3306;
   • NOTE: Database Userid and Database Password correspond with the User and Password properties for SingleStore.
3. On the Connection tab, click Connect.

To browse through tables exposed by the SingleStore JDBC Driver, right-click a table and click "Open in New Tab."

To execute SQL queries, use the SQL Commander tool: Click SQL Commander -> New SQL Commander. Select the Database Connection, Database, and Schema from the available menus.

See the "Supported SQL" chapter in the help documentation for more information on the supported SQL. See the "Data Model" chapter for table-specific information.
