Thanks to built-in query processing in the CData ODBC Driver, you know that as much query processing as possible is being pushed to Excel, freeing up local resources and computing power. Having created external tables for Excel in your SQL Server instance, you are now able to query local and remote data simultaneously. The statement to create an external table based on a Excel Sheet would look similar to the following:
You can refer to the Tables tab of the DSN Configuration Wizard to see the table definition.

The table column definitions must match those exposed by the CData ODBC Driver for Excel. PUSHDOWN is set to ON by default, meaning the ODBC Driver can leverage server-side processing for complex queries.ĬREATE EXTERNAL DATA SOURCE cdata_excel_sourceĬONNECTION_OPTIONS = 'DSN=CData Excel Sys',Īfter creating the external data source, use CREATE EXTERNAL TABLE statements to link to Excel data from your SQL Server instance. WITH IDENTITY = 'username', SECRET = 'password' Įxecute the following SQL command to create an external data source for Excel with PolyBase, using the DSN and credentials configured earlier.įor Excel, set SERVERNAME to 'localhost' or '127.0.0.1' and leave PORT empty.

NOTE: Since Excel does not require a User or Password to authenticate, you may use whatever values you wish for IDENTITY and SECRET.ĬREATE DATABASE SCOPED CREDENTIAL excel_creds Create an External Data Source for Excel DataĪfter configuring the connection, you need to create a master encryption key and a credential database for the external data source.Įxecute the following SQL command to create a new master key, 'ENCRYPTION,' to encrypt the credentials for the external data source.ĬREATE MASTER KEY ENCRYPTION BY PASSWORD = 'password' Įxecute the following SQL command to create credentials for the external data source connected to Excel data.
Navigate to the Tables tab to review the table definitions for Excel. The ExcelFile, under the Authentication section, must be set to a valid Excel File.Ĭlick "Test Connection" to ensure that the DSN is connected to Excel properly. To create an external data source in SQL Server using PolyBase, configure a System DSN (CData Excel Sys is created automatically). You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs. This is the last step of the driver installation. If you have not already, first specify connection properties in an ODBC DSN (data source name). And with PolyBase, you can also join SQL Server data with Excel data, using a single query to pull data from distributed sources.
When you issue complex SQL queries from SQL Server to Excel, the driver pushes down supported SQL operations, like filters and aggregations, directly to Excel and utilizes the embedded SQL engine to process unsupported operations (often SQL functions and JOIN operations) client-side.

The CData ODBC drivers offer unmatched performance for interacting with live Excel data using PolyBase due to optimized data processing built into the driver. This article walks through creating an external data source and external tables to grant access to live Excel data using T-SQL queries. When paired with the CData ODBC Driver for Excel, you get access to your Excel data directly alongside your SQL Server data.
PolyBase for SQL Server allows you to query external data by using the same Transact-SQL syntax used to query a database table.
