Use CData Connect Server to access Microsoft OneDrive data in Google Apps Script.
Google Apps Script gives you the ability to create custom functionality within your Google documents, including Google Sheets, Google Docs, and more. With CData Connect Server, you get a SQL Server interface for any of the 200+ sources supported by CData, including Microsoft OneDrive. The SQL Server protocol is natively supported through the JDBC service in Google Apps Script, so by utilizing Connect Server, you gain access to live Microsoft OneDrive data within your Google documents.
This article shows how to create a virtual database for Microsoft OneDrive in Connect Server and provides sample scripting for processing Microsoft OneDrive data in a Google Spreadsheet.
CData Connect Server provides a pure SQL Server interface for Microsoft OneDrive, allowing you to easily build reports from live Microsoft OneDrive data in Apps Script — without replicating the data to a natively supported database. As you build visualizations, Apps Script generates SQL queries to gather data. Using optimized data processing out of the box, CData Connect Server pushes all supported SQL operations (filters, JOINs, etc) directly to Microsoft OneDrive, leveraging server-side processing to quickly return the requested Microsoft OneDrive data.
Create a Virtual SQL Server Database for Microsoft OneDrive Data
CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.
- Login to Connect Server and click Connections.
- Select "Microsoft OneDrive" from Available Data Sources.
-
Enter the necessary authentication properties to connect to Microsoft OneDrive.
OneDrive uses the OAuth authentication standard. To authenticate using OAuth, you will need to create an app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties. See the OAuth section of the Help documentation for an authentication guide.
- Click Save Changes
- Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.
With the virtual database created, you are ready to connect to Microsoft OneDrive data from Apps Script.
Connect to Microsoft OneDrive Data with Apps Script
At this point, you should have configured a virtual database for Microsoft OneDrive in Connect Server. All that is left now is to use Google Apps Script to access Connect Server and work with your Microsoft OneDrive data in Google Sheets.
In this section, you will create a script (with a menu option to call the script) to populate a spreadsheet with Microsoft OneDrive data. We have created a sample script and explained the different parts. You can view the raw script at the end of the article.
1. Create an Empty Script
To create a script for your Google Sheet, click Tools Script editor from the Google Sheets menu:
2. Declare Class Variables
Create a handful of class variables to be available for any functions created in the script.
//replace the variables in this block with real values as needed var address = 'CONNECT_SERVER_URL:port'; var user = 'CONNECT_USER'; var userPwd = 'CONNECT_PASSWORD'; var db = 'onedrivedb'; var serverSslCert = '-----BEGIN CERTIFICATE----- ... -----END CERTIFICATE-----'; var clientSslCert = '-----BEGIN CERTIFICATE----- ... -----END CERTIFICATE-----'; var clientSslKey = '-----BEGIN CERTIFICATE----- ... -----END CERTIFICATE-----'; var dbUrl = 'jdbc:sqlserver://' + address + '/' + db + '?useSSL=true';
3. Add a Menu Option
This function adds a menu option to your Google Sheet, allowing you to use the UI to call your function.
function onOpen() { var spreadsheet = SpreadsheetApp.getActive(); var menuItems = [ {name: 'Write data to a sheet', functionName: 'connectToOneDriveData'} ]; spreadsheet.addMenu('Microsoft OneDrive Data', menuItems); }
4. Write a Helper Function
This function is used to find the first empty row in a spreadsheet.
/* * Finds the first empty row in a spreadsheet by scanning an array of columns * @return The row number of the first empty row. */ function getFirstEmptyRowByColumnArray(spreadSheet, column) { var column = spreadSheet.getRange(column + ":" + column); var values = column.getValues(); // get all data in one call var ct = 0; while ( values[ct] && values[ct][0] != "" ) { ct++; } return (ct+1); }
5. Write a Function to Write Microsoft OneDrive Data to a Spreadsheet
The function below writes the Microsoft OneDrive data, using the Google Apps Script JDBC functionality to connect to Connect Server, SELECT data, and populate a spreadsheet. When the script is run, two input boxes will appear:
The first one asks the user to input the name of a sheet to hold the data (if the spreadsheet does not exist, the function creates it).
The second asks the user to input the name of a Microsoft OneDrive table to read. If an invalid table is chosen, an error message appears and the function is exited.
Note, while the function is designed for use as a menu option, you can extend it for use as a spreadsheet formula.
/* * Reads data from a specified Microsoft OneDrive 'table' and writes it to the specified sheet. * (If the specified sheet does not exist, it is created.) */ function connectToOneDriveData() { var thisWorkbook = SpreadsheetApp.getActive(); //select a sheet and create it if it does not exist var selectedSheet = Browser.inputBox('Which sheet would you like the data to post to?',Browser.Buttons.OK_CANCEL); if (selectedSheet == 'cancel') return; if (thisWorkbook.getSheetByName(selectedSheet) == null) thisWorkbook.insertSheet(selectedSheet); var resultSheet = thisWorkbook.getSheetByName(selectedSheet); var rowNum = 2; //select a Microsoft OneDrive 'table' var table = Browser.inputBox('Which table would you like to pull data from?',Browser.Buttons.OK_CANCEL); if (table == 'cancel') return; var conn = Jdbc.getConnection(dbUrl, { user: user, password: userPwd, _serverSslCertificate: serverSslCert, _clientSslCertificate: clientSslCert, _clientSslKey: clientSslKey ); //confirm that var table is a valid table/view var dbMetaData = conn.getMetaData(); var tableSet = dbMetaData.getTables(null, null, table, null); var validTable = false; while (tableSet.next()) { var tempTable = tableSet.getString(3); if (table.toUpperCase() == tempTable.toUpperCase()){ table = tempTable; validTable = true; break; } } tableSet.close(); if (!validTable) { Browser.msgBox("Invalid table name: " + table, Browser.Buttons.OK); return; } var stmt = conn.createStatement(); var results = stmt.executeQuery('SELECT * FROM ' + table); var rsmd = results.getMetaData(); var numCols = rsmd.getColumnCount(); //if the sheet is empty, populate the first row with the headers var firstEmptyRow = getFirstEmptyRowByColumnArray(resultSheet, "A"); if (firstEmptyRow == 1) { //collect column names var headers = new Array(new Array(numCols)); for (var col = 0; col < numCols; col++){ headers[0][col] = rsmd.getColumnName(col+1); } resultSheet.getRange(1, 1, headers.length, headers[0].length).setValues(headers); } else { rowNum = firstEmptyRow; } //write rows of Microsoft OneDrive data to the sheet var values = new Array(new Array(numCols)); while (results.next()) { for (var col = 0; col < numCols; col++) { values[0][col] = results.getString(col + 1); } resultSheet.getRange(rowNum, 1, 1, numCols).setValues(values); rowNum++; } results.close(); stmt.close(); }
When the function is completed, you have a spreadsheet populated with your Microsoft OneDrive data, and you can now leverage all of the calculating, graphing, and charting functionality of Google Sheets anywhere you have access to the Internet.
