PowerApps - Update Vs UpdateIf functions

In this article, we will understand when to use Update and when to use UpdateIf function. We will understand the functionalities of Update and UpdateIf function using some simple examples.

Note:

  • Update function updates the entire record in a database
  • UpdateIf and Patch functions update only specific columns
  • Update and UpdateIf both return table as a modified data source.
  • The Update function will change all the columns of the row. So, if you don’t provide the new value for any specific column, it will update the column to a blank (“”) value in the table.

PowerApps Update function Syntax

Update( DataSource, OldRecord, NewRecord [, All ] )

  • DataSouce: This is Required. Pass the table or collection or data source on which Update operation will be fired
  • OldRecords: This is Required. The existing records to be updated.
  • NewRecords: This is Required.
    • The old records will be replaced by this record.
    • All the columns will be updated.
    • If the NewRecords-column is not having the value, then it will be updated as blank.
  • All: This is Optional.
    • There could be multiple records matching the old record. If you want to update all the records, then specify All otherwise only one record will be updated.

PowerApps UpdateIf function Syntax

UpdateIf( DataSource, Condition1, ChangeRecord1 [, Condition2, ChangeRecord2, ... ] )

  • DataSouce: This is Required. Pass the table or collection or data source on which Update operation will be fired.
  • Condition(s): This is Required. Condition to filter the data from the data source. You can use column names from the data source specified in the first argument.
  • ChangeRecord(s): the records which satisfy the above condition, can be changed using this parameter. In curly brackets, you can specify the column name and a new value of that column.
