Google Drive Connector for SSAS
In this article you will learn how to integrate Using Google Drive Connector you will be able to connect, read, and write data from within SSAS. Follow the steps below to see how we would accomplish that. The driver mentioned above is part of ODBC PowerPack which is a collection of high-performance Drivers for various API data source (i.e. REST API, JSON, XML, CSV, Amazon S3 and many more). Using familiar SQL query language you can make live connections and read/write data from API sources or JSON / XML / CSV Files inside SQL Server (T-SQL) or your favorite Reporting (i.e. Power BI, Tableau, Qlik, SSRS, MicroStrategy, Excel, MS Access), ETL Tools (i.e. Informatica, Talend, Pentaho, SSIS). You can also call our drivers from programming languages such as JAVA, C#, Python, PowerShell etc. If you are new to ODBC and ZappySys ODBC PowerPack then check the following links to get started. |

Create Data Source in ZappySys Data Gateway based on API Driver
-
Download and install ZappySys ODBC PowerPack.
-
Search for gateway in start menu and Open ZappySys Data Gateway:
-
Go to Users Tab to add our first Gateway user. Click Add; we will give it a name tdsuser and enter password you like to give. Check Admin option and click OK to save. We will use these details later when we create linked server:
-
Now we are ready to add a data source. Click Add, give data source a name (Copy this name somewhere, we will need it later) and then select Native - ZappySys API Driver. Finally, click OK. And it will create the Data Set for it and open the ZS driver UI.
GoogleDriveDSN
-
When the Configuration window appears give your data source a name if you haven't done that already, then select "Google Drive" from the list of Popular Connectors. If "Google Drive" is not present in the list, then click "Search Online" and download it. Then set the path to the location where you downloaded it. Finally, click Continue >> to proceed with configuring the DSN:
GoogleDriveDSNGoogle Drive -
Now it's time to configure the Connection Manager. Select Authentication Type, e.g. Token Authentication. Then select API Base URL (in most cases, the default one is the right one). More info is available in the Authentication section.
Steps to get Google Drive Credentials
To make this work you will have to create an OAuth application. To register an App, perform the following steps (Detailed steps found in the help link at the end):
- Go to Google API Console
- From the Project Dropdown (usually found at the top bar) click Select Project
- On Project Propup click CREATE PROJECT
- Once project is created you can click Select Project to switch the context (You can click on Notification link or Choose from Top Dropdown)
- Click ENABLE APIS AND SERVICES
- Now we need to enable Google Drive API.
- Search Google Drive API. Select and click ENABLE
- Go to back to main screen of Google API Console
- Click OAuth Concent Screen Tab. Enter necessary details and Save.
- Click Credentials Tab
- Click CREATE CREDENTIALS (some where in topbar) and select OAuth Client ID option.
- When prompted Select Application Type as Desktop App and click Create to receive your ClientID and Secret. Later on you can use this information now to configure Connection with UseCustomApp=true.
NOTE: If you are planning to use your current data connection/token for automated processes, we recommend that you use a generic account for token generation when the login box appears (e.g. sales_automation@mycompany.com instead of bob_smith@mycompany.com). When you use a personal account which is tied to a specific employee profile and that employee leaves the company, the token may become invalid and any automated processes using that token will fail. Another potentially unwanted effect of using a personal token is incorrect logging; the API calls (e.g. Read, Edit, Delete, Upload) made with that token will record the specific user as performing the calls instead of an automated process.
- Go to OAuth Consent Screen tab. Under Publishing Status click PUBLISH APP to ensure your refresh token doesnt expire often. If you planning to use App for Private use then do not have to worry about Verification Status after Publish.

Use these steps to authenticate as service account rather than Google / GSuite User. Learn more about service account here Basically to call Google API as Service account we need to perform following steps listed in 3 sections (Detailed steps found in the help link at the end)Create Project
First thing is create a Project so we can call Google API. Skip this section if you already have Project (Go to next section)- Go to Google API Console
- From the Project Dropdown (usually found at the top bar) click Select Project
- On Project Propup click CREATE PROJECT
- Once project is created you can click Select Project to switch the context (You can click on Notification link or Choose from Top Dropdown)
- Click ENABLE APIS AND SERVICES
- Now we need to Enable two APIs one by one (Drive API).
- Search Drive. Select and click ENABLE
Create Service Account
Once Project is created and APIs are enabled we can now create a service account under that project. Service account has its ID which looks like some email ID (not to confuse with Google /Gmail email ID)- Go to Create Service Account
- From the Project Dropdown (usually found at the top bar) click Select Project
- Enter Service account name and Service account description
- For Role, do not select anything for now and Click Continue and then click Done. Next we will create Key.
Create Key
Once service account is created we need to create key file (i.e. credentials).- In the Cloud Console, click the email address for the service account that you created.
- Click Keys.
- Click Add key, then click Create new key.
- Click Create and select P12 format. A P12 key file is downloaded to your computer. We will use this file in our API connection.
- Click Close.
- Now you may use downloaded *.p12 key file as secret file and Service Account Email as Client ID (e.g. some-service-account-name@your-project-id.iam.gserviceaccount.com ).
Add Permission
Now last thing is give read/write permission to Service Account. Basically you can create or open Google Sheet and add the Service Account as an editor to it as below.- Copy the email address of your service account we created in previous step (its usually like this some-service-account-name@your-project-id.iam.gserviceaccount.com).
- Create or select an existing Google Docs File.
- Navigate to Google Docs File for which you like to give read/write access to Service Account.
- Click on the Share button in the top right, and add the email address of the service account as an editor. Here is how to share file(s) with specific people. Juse share with Service Account (use Service Account Email found on previous section)
Fill in all required parameters and set optional parameters if needed:
GoogleDriveDSNGoogle DriveService Account (Using Private Key File) [OAuth]https://www.googleapis.com/Required Parameters Service Account Email Fill in the parameter... Service Account Private Key Path (i.e. *.p12) Fill in the parameter... Optional Parameters Scope Fill in the parameter... RetryMode Fill in the parameter... RetryStatusCodeList Fill in the parameter... RetryCountMax Fill in the parameter... RetryMultiplyWaitTime Fill in the parameter... -
Once the data source has been configured, you can preview data. Select the Preview tab and use settings similar to the following to preview data:
-
Click OK to finish creating the data source.
Read Google Drive data in SSAS cube
With the data source created in the Data Gateway (previous step), we're now ready to read Google Drive data in an SSAS cube. Before we dive in, open Visual Studio and create a new Analysis Services project. Then, you're all set!
Create data source based on ZappySys Data Gateway
Let's start by creating a data source for a cube, based on the Data Gateway's data source we created earlier. So, what are we waiting for? Let's do it!
- Create a new data source:
- Once a window opens, select Create a data source based on an existing or new connection option and click New...:
-
Here things become a little complicated, but do not despair, it's only for a little while.
Just perform these little steps:
- Select Native OLE DB\SQL Server Native Client 11.0 as provider.
- Enter your Server name (or IP address) and Port, separated by a comma.
- Select SQL Server Authentication option for authentication.
- Input User name which has admin permissions in the ZappySys Data Gateway.
- In Database name field enter the same data source name you use in the ZappySys Data Gateway.
- Hopefully, our hard work is done, when we Test Connection.
GoogleDriveDSNGoogleDriveDSNIf SQL Server Native Client 11.0 is not listed as Native OLE DB provider, try using these:- Microsoft OLE DB Driver for SQL Server
- Microsoft OLE DB Provider for SQL Server
- Indeed, life is easy again:
Add data source view
We have data source in place, it's now time to add a data source view. Let's not waste a single second and get on to it!
- Start by right-clicking on Data Source Views and then choosing New Data Source View...:
- Select the previously created data source and click Next:
- Ignore the Name Matching window and click Next.
-
Add the tables you will use in your SSAS cube:
For cube dimensions, consider creating a Virtual Table in the Data Gateway's data source. Use the
DISTINCT
keyword in theSELECT
statement to get unique values from the facts table, like this:SELECT DISTINCT Country FROM Customers
For demonstration purposes we are using sample tables which may not be available in Google Drive. - Review your data source view and click Finish:
- Add the missing table relationships and you're done!
Create cube
We have a data source view ready to be used by our cube. Let's create one!
- Start by right-clicking on Cubes and selecting New Cube... menu item:
- Select tables you will use for the measures:
- And then select the measures themselves:
- Don't stop and select the dimensions too:
- Move along and click Finish before the final steps:
- Review your cube before processing it:
- It's time for the grand finale! Hit Process... to create the cube:
- A splendid success!
Execute MDX query
The cube is created and processed. It's time to reap what we sow! Just execute an MDX query and get Google Drive data in your SSAS cube:

Create Custom Stored Procedure in ZappySys Driver
You can create procedures to encapsulate custom logic and then only pass handful parameters rather than long SQL to execute your API call.
Steps to create Custom Stored Procedure in ZappySys Driver. You can insert Placeholders anywhere inside Procedure Body. Read more about placeholders here
-
Go to Custom Objects Tab and Click on Add button and Select Add Procedure:
-
Enter the desired Procedure name and click on OK:
-
Select the created Stored Procedure and write the your desired stored procedure and Save it and it will create the custom stored procedure in the ZappySys Driver:
Here is an example stored procedure for ZappySys Driver. You can insert Placeholders anywhere inside Procedure Body. Read more about placeholders here
CREATE PROCEDURE [usp_get_orders] @fromdate = '<<yyyy-MM-dd,FUN_TODAY>>' AS SELECT * FROM Orders where OrderDate >= '<@fromdate>';
-
That's it now go to Preview Tab and Execute your Stored Procedure using Exec Command. In this example it will extract the orders from the date 1996-01-01:
Exec usp_get_orders '1996-01-01';
-
Let's generate the SQL Server Query Code to make the API call using stored procedure. Go to Code Generator Tab, select language as SQL Server and click on Generate button the generate the code.
As we already created the linked server for this Data Source, in that you just need to copy the Select Query and need to use the linked server name which we have apply on the place of [MY_API_SERVICE] placeholder.
SELECT * FROM OPENQUERY([MY_API_SERVICE], 'EXEC usp_get_orders @fromdate=''1996-07-30''')
-
Now go to SQL served and execute that query and it will make the API call using stored procedure and provide you the response.
Create Custom Virtual Table in ZappySys Driver
ZappySys API Drivers support flexible Query language so you can override Default Properties you configured on Data Source such as URL, Body. This way you don't have to create multiple Data Sources if you like to read data from multiple EndPoints. However not every application support supplying custom SQL to driver so you can only select Table from list returned from driver.
If you're dealing with Microsoft Access and need to import data from an SQL query, it's important to note that Access doesn't allow direct import of SQL queries. Instead, you can create custom objects (Virtual Tables) to handle the import process.
Many applications like MS Access, Informatica Designer wont give you option to specify custom SQL when you import Objects. In such case Virtual Table is very useful. You can create many Virtual Tables on the same Data Source (e.g. If you have 50 URLs with slight variations you can create virtual tables with just URL as Parameter setting.
-
Go to Custom Objects Tab and Click on Add button and Select Add Table:
-
Enter the desired Table name and click on OK:
-
And it will open the New Query Window Click on Cancel to close that window and go to Custom Objects Tab.
-
Select the created table, Select Text Type AS SQL and write the your desired SQL Query and Save it and it will create the custom table in the ZappySys Driver:
Here is an example SQL query for ZappySys Driver. You can insert Placeholders also. Read more about placeholders here
SELECT "ShipCountry", "OrderID", "CustomerID", "EmployeeID", "OrderDate", "RequiredDate", "ShippedDate", "ShipVia", "Freight", "ShipName", "ShipAddress", "ShipCity", "ShipRegion", "ShipPostalCode" FROM "Orders" Where "ShipCountry"='USA'
-
That's it now go to Preview Tab and Execute your custom virtual table query. In this example it will extract the orders for the USA Shipping Country only:
SELECT * FROM "vt__usa_orders_only"
-
Let's generate the SQL Server Query Code to make the API call using stored procedure. Go to Code Generator Tab, select language as SQL Server and click on Generate button the generate the code.
As we already created the linked server for this Data Source, in that you just need to copy the Select Query and need to use the linked server name which we have apply on the place of [MY_API_SERVICE] placeholder.
SELECT * FROM OPENQUERY([MY_API_SERVICE], 'EXEC [usp_get_orders] ''1996-01-01''')
-
Now go to SQL served and execute that query and it will make the API call using stored procedure and provide you the response.
