How to download files from Google Drive using SSIS

Introduction

In today’s data-driven world, the ability to seamlessly integrate and transfer files between different platforms is crucial for efficient business operations. If you’re a user of SQL Server Integration Services (SSIS) and looking to integrate Google Drive into your data workflow, you’re in luck. ZappySys SSIS PowerPack offers a powerful Google Drive Connector that makes downloading files from Google Drive a breeze. In this guide, we’ll walk you through the process of downloading files from Google Drive using SSIS and the ZappySys SSIS PowerPack Google Drive Connector.

How to download a single file from Google Drive

In the API Source Component, we’ve chosen the API Connection Manager. Next, we need to configure the remaining properties of the component to download the single file from Google Drive.

  1. Choose the Download a file endpoint from the “Select Table/Endpoint” dropdown menu.
  2. To access detailed API documentation for downloading files, you can click on the following link: Help for: Download a File.
  3. Please choose a File ID from the drop-down menu to indicate which file you wish to download. This is an essential parameter for the download process.
  4. Please indicate the desired filename for the file being downloaded by setting the FileName parameter.
  5. If you intend to replace the local file with the one being downloaded, please select the ‘AlwaysOverwrite‘ option from the dropdown menu labeled ‘FileOverwriteMode‘. Alternatively, you can choose ‘FileIfExists’ or ‘SkipIfExists’ based on your specific needs.

Please refer to the sample screenshot below.

Once you have configured all the mentioned properties above, please click on the “Preview Data” button to initiate the API call. With just a few clicks, we have successfully configured the call to Google Drive using the ZappySys Google Drive Connector for downloading a Single file from Google Drive.

How to download multiple files from Google Drive

In the API Destination Component, we have chosen the API Connection Manager. Now, we must proceed to configure the remaining properties of the component to facilitate the download of multiple files from Google Drive. Additionally, we should make use of an OLE DB Source and Derived Column component to map the files for the download process.

  1. Drag and drop the OLE DB Source Component from the SSIS Toolbox. Double-click on the OLE DB Source Component to initiate its configuration.
