Connect to Snowflake data in MicroStrategy Developer using the CData ODBC Driver for Snowflake.
MicroStrategy is an analytics and mobility platform that enables data-driven innovation. When you pair MicroStrategy with the CData ODBC Driver for Snowflake, you gain database-like access to live Snowflake data from MicroStrategy, expanding your reporting and analytics capabilities. In this article, we walk through creating a database instance for Snowflake in MicroStrategy Developer and creating a Warehouse Catalog based on Snowflake data.
The CData ODBC driver offers unmatched performance for interacting with live Snowflake data in MicroStrategy due to optimized data processing built into the driver. When you issue complex SQL queries from MicroStrategy to Snowflake, the driver pushes supported SQL operations, like filters and aggregations, directly to Snowflake and utilizes the embedded SQL engine to process unsupported operations (often SQL functions and JOIN operations) client-side. With built-in dynamic metadata querying, you can visualize and analyze Snowflake data using native MicroStrategy data types.
About Snowflake Data Integration
CData simplifies access and integration of live Snowflake data. Our customers leverage CData connectivity to:
- Reads and write Snowflake data quickly and efficiently.
- Dynamically obtain metadata for the specified Warehouse, Database, and Schema.
- Authenticate in a variety of ways, including OAuth, OKTA, Azure AD, Azure Managed Service Identity, PingFederate, private key, and more.
Many CData users use CData solutions to access Snowflake from their preferred tools and applications, and replicate data from their disparate systems into Snowflake for comprehensive warehousing and analytics.

Getting Started
Connect to Snowflake as an ODBC Data Source
Information for connecting to Snowflake follows, along with different instructions for configuring a DSN in Windows and Linux environments (the ODBC Driver for Snowflake must be installed on the machine hosting the connected MicroStrategy Intelligence Server).
To connect to Snowflake:
- Set User and Password to your Snowflake credentials and set the AuthScheme property to PASSWORD or OKTA.
- Set URL to the URL of the Snowflake instance (i.e.: https://myaccount.snowflakecomputing.com).
- Set Warehouse to the Snowflake warehouse.
- (Optional) Set Account to your Snowflake account if your URL does not conform to the format above.
- (Optional) Set Database and Schema to restrict the tables and views exposed.
See the Getting Started guide in the CData driver documentation for more information.
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.
Windows
If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.
Linux
If you are installing the CData ODBC Driver for Snowflake in a Linux environment, the driver installation predefines a system DSN. You can modify the DSN by editing the system data sources file (/etc/odbc.ini) and defining the required connection properties.
/etc/odbc.ini

For specific information on using these configuration files, please refer to the help documentation (installed and found online).
Create a Snowflake Database Instance in MicroStrategy Developer
You can connect to Snowflake in MicroStrategy Developer by adding a database instance based on the CData ODBC Driver for Snowflake.*
- Open MicroStrategy Developer and select a Project Source.
- Navigate to Administration -> Configuration Managers -> Database Instances and right-click to add a new instance.
- Name the instance, select Generic DBMS as the database connection type, and create a new database connection.
- In the database connection wizard, name the connection and create a new Database Login name, using filler values for the user and password.
- Select the DSN that you configured earlier as the ODBC data source (i.e., CData Snowflake Sys).
- Select the newly created database connection.
- In the Project Source, right-click the project and open the Project configuration.
- Navigate to Database Instances and select the newly created database instance.
- Close MicroStrategy Developer and restart the connected MicroStrategy Intelligence Server to complete the database instance creation.
With the database instance configured, you will now be able to connect to Snowflake data from the Warehouse Catalog and Data Import.
Connect to Snowflake Data from the Warehouse Catalog
Once you have created a database instance based on the ODBC Driver for Snowflake, you can connect to data from the Warehouse Catalog.
- Select your project and click Schema -> Warehouse Catalog.
- In the Read Settings for the Catalog, click Settings and set the queries to retrieve the schema:
- To retrieve the list of tables, use the following query:
SELECT CatalogName NAME_SPACE, TableName TAB_NAME FROM SYS_TABLES
- To retrieve the list of columns for selected tables, use the following query:
SELECT DISTINCT CatalogName NAME_SPACE, TableName TAB_NAME, ColumnName COL_NAME, DataTypeName DATA_TYPE, Length DATA_LEN, NumericPrecision DATA_PREC, NumericScale DATA_SCALE FROM SYS_TABLECOLUMNS WHERE TableName IN (#TABLE_LIST#) ORDER BY 1,2,3
- To retrieve the list of tables, use the following query:
- Select tables to be used in the project.
If you are interested in connecting to Snowflake from other MicroStrategy products, you can read about connecting from MicroStrategy Web and connecting from MicroStrategy Desktop.
Note: connecting using a ODBC driver requires a 3- or 4-tier architecture.
