Excel Spreadsheet Automation on Google Spanner Data with the QUERY Formula

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

The syntax of the CDATAQUERY formula is the following:

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

This formula requires three inputs:

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

• Connection: Either the connection name, such as GoogleSpannerConnection1, or a connection string. The connection string consists of the required properties for connecting to Google Spanner data, separated by semicolons.

  Google Spanner uses the OAuth authentication standard. To authenticate using OAuth, you can use the embedded credentials or register an app with Google.

  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 Google Spanner 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 Customer WHERE Id = '"&B5&"'","ProjectId="&B1&";InstanceId="&B2&";Database="&B3&";InitiateOAuth="&B4&";Provider=GoogleSpanner",B6)
