Updated: Jan 8

Hey there, Power App enthusiasts! If you've ever found yourself puzzled over patching Dataverse columns, we've got your back. We've created a comprehensive video guide Patch Dataverse Columns with Power Apps that dives deep into patching various Dataverse column types. But if you're more of a reader, this blog post is your go-to resource!

Dataverse Text Columns: More Than Just Words

Dataverse Text and Dataverse Multi-Line columns are the backbone of most databases. While they offer various display options, at their core, they're all about storing text. Single Lines of Text have a character limit of 4000, while Multiple Lines can store just over a million characters. In Power Apps, patching these types of columns is a breeze. Here's a quick example:

Patch('YourTable', Defaults('YourTable'), {Title: "Hello, World!"})

Dataverse Number and Currency Columns: The Numbers Game

When it comes to Dataverse Number and Currency columns, precision is key. Number columns can store integers or decimals, while Currency columns are formatted to handle monetary values. Patching these columns in Power Apps is straightforward:

Patch('YourTable', Defaults('YourTable'), {Price: 19.99})

Dataverse Date and Time Columns: Tick Tock

Dataverse Date and Time columns are perfect for scheduling, logging, and more. Power Apps offers built-in functions like `Today()` and `Now()` to make patching these columns a walk in the park.

Patch('YourTable', Defaults('YourTable'), {MeetingDate: Today()})

Dataverse Choice and Yes/No Columns: The Decision Makers

Choice columns in Dataverse are ideal for fields with a predefined set of options, like 'Status' or 'Priority'. Yes/No columns simplify it even further, boiling it down to a binary choice. Here's how to patch them:

Patch('YourTable', Defaults('YourTable'), {Status: {Value: "Completed"}})

Dataverse Lookup Columns: The Relationship Builders

Dataverse Lookup columns are all about creating relationships between tables. They're essential for maintaining data integrity and making your apps more dynamic. To patch these columns, you'll need to provide a record, like so:

Patch('YourTable', Defaults('YourTable'), {Customer: LookUp('CustomersTable', ID = 1)})

Dataverse File and Image Columns: Worth a Thousand Words

Dataverse File and Image columns allow you to store a variety of media. While File columns can handle documents like PDFs and Excel sheets, Image columns are optimized for image files. Here's how to patch them:

Patch('YourTable', Defaults('YourTable'), {Document: AddMediaButton1.Media})
