Search for a data in spreadsheet or tinyDB

Hi there. So I was building an app in which the user will connect to a wifi clock using a barcode.
Basically, the user has to scan a barcode or QR code and the app will convert the QR into a text and search for the entry for the text like, the text is "abc" and the app will get this text using qr scan and will search for the entry or other related data to this text. How can i do so? As a newbie i don't know much about MIT app inventor so please help me out.

You can learn.

Here are some resources to help you learn to use the AI2 tools. A very good way to learn App Inventor is to read the free Inventor's Manual here in the AI2 free online eBook App Inventor 2 Book: Create Your Own Android Apps ... the links are at the bottom of the Web page. The book 'teaches' users how to program with AI2 blocks.

There is a free programming course here Course In A Box and the aia files for the projects in the book are here: App Inventor 2 Book: Create Your Own Android Apps

How to do a lot of basic things with App Inventor are described here: How do you...? .
