Excel Spreadsheet Automation on Snowflake Data with the QUERY Formula

The CData Excel Add-In for Snowflake provides formulas that can edit, save, and delete Snowflake data. The following three steps show how you can automate the following task: Search Snowflake data for a user-specified value and then organize the results into an Excel spreadsheet.

Getting Started

---

The syntax of the CDATAQUERY formula is the following:

=CDATAQUERY(Query, [Connection], [Parameters], [ResultLocation]);

This formula requires three inputs:

• Query: The declaration of the Snowflake data records you want to retrieve or the modifications to be made, written in standard SQL.

• Connection: Either the connection name, such as SnowflakeConnection1, or a connection string. The connection string consists of the required properties for connecting to Snowflake data, separated by semicolons.

  To connect to Snowflake:

  1. Set User and Password to your Snowflake credentials and set the AuthScheme property to PASSWORD or OKTA.
  2. Set URL to the URL of the Snowflake instance (i.e.: https://myaccount.snowflakecomputing.com).
  3. Set Warehouse to the Snowflake warehouse.
  4. (Optional) Set Account to your Snowflake account if your URL does not conform to the format above.
  5. (Optional) Set Database and Schema to restrict the tables and views exposed.
  6. (Optional) If MFA is enabled on your Snowflake account (via Duo Security), set MFACode to the passcode generated by your Duo authenticator app.

  See the Getting Started guide in the CData driver documentation for more information.

• ResultLocation: The cell that the output of results should start from.

Pass Spreadsheet Cells as Inputs to the Query

The procedure below results in a spreadsheet that organizes all the formula inputs in the first column.

1. Define cells for the formula inputs. In addition to the connection inputs, add another input to define a criterion for a filter to be used to search Snowflake data, such as Id.
2. In another cell, write the formula, referencing the cell values from the user input cells defined above. Single quotes are used to enclose values such as addresses that may contain spaces.

=CDATAQUERY("SELECT * FROM Products WHERE Id = '"&B10&"'","Authscheme="&B1&";URL="&B2&";User="&B3&";Password="&B4&";Server="&B5&";Database="&B6&";Warehouse="&B7&";Account="&B8&";MFACode="&B9&";Provider=Snowflake",B11)
