Connecting to SQL Server
Zoomdata's SQL Server connector lets you access the data available in this SQL query engine for visualization and exploration within the Zoomdata Client. Zoomdata supports SQL Server 2012 11.0.21 and later versions.
The table below lists information on the features that are supported by SQL Server:
|Supports Distinct Count?||Yes|
|Supports Live Mode/ Playback?||Yes|
|Supports Group-by Time?||Yes|
|Supports Multi Group-by Charts?||Yes|
|Supports Box Plot?||Yes|
|Custom SQL Capable?||Yes|
|Supports Last Value?||No|
Starting with Zoomdata v2.5.3, the SQL Server connector will require a JDBC driver to be configured before you can connect to your data source. You can download the driver from the vendor's site. If you are upgrading, keep in mind you will need to configure the JDBC driver (refer to the article Upgrading Zoomdata Server to v2.5 for instructions). For more information, refer to the Add a JDBC Driver article.

- Select Next to continue to the next setup page.
This page defines the connection source for Zoomdata to be able to access the data source. If this is the first time setting up a connection, then you need to input the necessary credentials. If a validated connection already exists, you are given the option to use it.
- To create a new connection, select the Input New Credentials option.
- Enter a unique name for the connection (to help distinguish between other connections in this Zoomdata account).
Specify the connection name and JDBC URL. The JDBC URL for SQL Server database being connected, must be:
If authentication is required, provide the username and password.
Click Validate .
If successfully validated, the connection is saved.
The Tables page lets you select the schema and table to connect with and provides a preview of the selected table. In addition, caching options and toggling the availability of the fields can be done on this page.
- Select the schema and then select the desired table to connect to Zoomdata.
- Create a Custom SQL query, if needed.
- Toggle the caching options (SparkIt and Caching) as needed (by default, SparkIt is disabled; access the article How Zoomdata Caches the Data for more information).
- Toggle the availability of the fields, as needed.
- Click Next to continue.
The Fields page lets you (1) configure attribute options, (2) create custom labels for the fields in your data source (that will be displayed in the charts), (3) manage the Volume metric, and (4) work with Calculations.

If you are setting up a new connection, the Calculations section will not be available until after the connection is saved.
- Click Next to continue.
The Refresh page lets you schedule asynchronous jobs to update the source metadata. For guidance to set up a refresh schedule, refer to the article Using the Zoomdata Scheduler .
On the Charts page, you can:
- Edit Global Default Settings .
- Select the Standard and, if available, Custom chart styles to be used with the data source.
- Set default parameters (group, sub-group, colors, sorting, and so on) for each chart style.
Click Finish to save your changes. Once your data connection has been established, it will be listed under the My Data Sources section of the page.
