Create a Data Source Name in iODBC with the CData ODBC Driver for SingleStore and work with SingleStore data in Microsoft Excel on Mac OS X.
Microsoft Excel features calculations, graphing tools, pivot tables, and a macro programming language that allows users to work with data in many of the ways that suit their needs, whether on a Windows machine or a Macintosh machine. This article walks through creating a DSN for SingleStore data in iODBC and accessing SingleStore data in Microsoft Excel, all on a machine running Mac OS X.
Installing the CData ODBC Drivers on Mac OS X
The CData ODBC Driver for SingleStore is preconfigured for the iODBC driver manager, as are many other products like Microsoft Excel. This makes the driver easy to use with these tools.
Licensing the Driver
In a terminal run the following commands to license the driver. To activate a trial license, omit the key input.
cd "/Applications/CData ODBC Driver for SingleStore/bin" sudo ./install-license <key>
Defining a DSN for iODBC with odbc.ini
You can define ODBC data sources in sections in the odbc.ini file. User data sources can only be accessed by the user account whose home folder the odbc.ini is located in. System data sources can be accessed by all users. You can find the correct odbc.ini in the following paths:
Privileges | Path | |
---|---|---|
User | /Users/myuser/Library/ODBC/odbc.ini | |
System | /Library/ODBC/odbc.ini |
Modifying iODBC's system-wide settings requires elevated permissions; to do so, you can use following to open a text editor from the terminal:
sudo nano /Library/ODBC/odbc.ini
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.
When you configure the DSN, 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.
In addition to the connection properties required to connect to SingleStore, the Driver property specifies either a driver definition in the odbcinst.ini file or the path to the driver library. Place your connection properties at the beginning of odbc.ini:
[CData SingleStore Sources] Driver = CData ODBC Driver for SingleStore User = myUser Password = myPassword Database = NorthWind Server = myServer Port = 3306
If you wish to authenticate using OAuth, you will need to add an additional connection property to ensure that the OAuth flow can execute properly:
Other = CheckPromptMode=False
Mac OS validates our drivers separately so you need to copy the license file to the appropriate path as well. After you have configured odbc.ini, run the following command.
sudo cp /Applications/CData ODBC Driver for SingleStore/lib/CData.ODBC.SingleStore.lic /Users/<YOUR_USER>/Library/Containers/com.microsoft.Excel/Data/.cdata/
Additionally, in the ODBC Data Sources section, the DSN must be set to a driver defined in the odbcinst.ini file. For example, below is the entry for the DSN created during the driver install:
[ODBC Data Sources]
CData SingleStore Source = CData ODBC Driver for SingleStore
Registering a DSN for iODBC with odbcinst.ini
You may need to modify the installed driver definition if you change the path to the driver library. To register an ODBC driver, modify the odbcinst.ini file. With iODBC, drivers can be available to only one user account or drivers can be available system wide. You can find the correct odbcinst.ini in the following paths:
Privileges | Path | |
---|---|---|
User | /Users/myuser/Library/ODBC/odbcinst.ini | |
System | /Library/ODBC/odbcinst.ini |
Drivers are defined in sections in the odbcinst.ini file. The section name specifies the name of the driver. In this section, the Driver property specifies the path to the driver library. The driver library is the .dylib file located in the lib subfolder of the installation directory, by default in /Applications/CData ODBC Driver for SingleStore.
[CData ODBC Driver for SingleStore]
Driver = /Applications/CData ODBC Driver for SingleStore/lib/libsinglestore.odbc.dylib
The ODBC Drivers section must also contain a property with the driver name, set to "Installed".
[ODBC Drivers]
CData ODBC Driver for SingleStore = Installed
Testing the Connection
You can test your connection using the iODBC administrator.
- Open a terminal and enter the following command to start the iODBC Administrator with the necessary permissions:
sudo /Applications/iODBC/iODBC\ Administrator64.app/Contents/MacOS/iODBC\ Administrator64
- On the Users tab, select CData SingleStore Source.
- Click the Test button.
Accessing SingleStore Data from Microsoft Excel
You can use the DSN configured above to access SingleStore data from Microsoft Excel.
- Open Microsoft Excel and open a spreadsheet (new or existing).
- Navigate to the data ribbon, click the drop down next to "Get Data (Power Query)," and select "From Database (Microsoft Query)"
- Select the User or System DSN that you previously configured and click OK.
- Build your SQL query in the Microsoft Query wizard:
- Click Return Data to execute the query and pull data into Excel.
Using the CData ODBC Driver for SingleStore, you can easily pull your SingleStore data directly into Excel. Once there, you can leverage all of the powerful features native to Excel to analyze, report, transform your SingleStore data, and more!
