PowerApps - Patch function with examples

In this article, we will understand the PowerApps Patch function. We will understand the functionalities and limitations of the Patch function using some simple examples.


  • The Patch function Modifies an existing record or Creates a new record.
  • Using the Patch function, you can only update one record at a time or create a single record only.
  • You have to use ForAll function if you want to update or create multiple records using Patch function
  • To create a record using the Patch function, you need to use the Defaults function to create a base record with default values.

PowerApps Patch function Syntax

Patch( DataSource, BaseRecord, ChangeRecord1 [, ChangeRecord2, … ])

  • DataSouce: This is Required. Pass the table or collection or data source on which Patch operation will be fired.
  • BaseRecord: This is Required:
    • Filter the records which need to modify or create.
    • If the record is from the data source, the records will be modified
    • If the record is from the Default result, then a new record will be created.


Table Name: Weathers

PowerApps Patch function - Create record

  • DataSource: Weathers
  • Here, we are going to use the Patch function to create a record.
  • As mentioned earlier, you can create only one record using the Patch function.
  • Also, you need to use the Defaults function which will create a base record and then update with column values you provide.
  • If you don’t specify columns values, then it will take blank values for a new record in those columns.
  • You need to provide values for all the mandatory columns.
  • In the below example, Name is a mandatory column, so have specified a sample name. you can observe that the record is created with the rest of the column having blank values.

Patch(Weathers, Defaults(Weathers), {Temperature: 33, Name: "Sample Name"});


Powerapps patch function create records

PowerApps Patch multiple records using Patch and ForAll

  • DataSource: Weathers
  • You can update multiple records using Patch in ForAll function or you can use UpdateIf function
  • In this example, I have created a collection and, on that collection, I have applied ForAll because the function cannot operate on the same data source that is used in ForAll.

// Create a Collecction

ClearCollect(TempCollection, Weathers);

// Loop through the collection created and patch the records.
