Renaming multiple fields and joining tables



I have a table PersonList with fields: Contact_Id, Contact_Name and Contact_Email
Then I have a table Employees with fields: Employee_Id, Employee_Name, Employee_Email and Status


How would I go about renaming Contact_id to ID and Employee_Id to ID (and doing the same for other columns as well) and then joining everything in one table?
The solution I have for now is to set temporary tables and rename columns one by one (for example):

Set(PersonListTemp; RenameColumns(PersonListTemp; "Contact_Id"; "ID"));;

But there has to be a way where I don't have to make so many new tables?


Thanks in advance!

Re: Renaming multiple fields and joining tables

Hi @jernejp ,

Could you please share a bit more about your scenario?

Do you want to rename column names within your underlying tables (original tables)?


If you want to rename column names within your underlying tables (original tables), I afraid that there is no way to achieve your needs in PowerApps currently.


As an alternative solution, you could consider create a temporary table for each of your original table with renamed columns, then merge the temporary tables into single one table.


I have made a test on my side, please take a try with the following workaround:

Set the OnSelect property of a button to following:

               RenameColumns(PersonList, "Contact_Id", "ID", "Contact_Name", "Name", "Contact_Email", "Email"),
RenameColumns(Employees, "Employee_Id", "ID", "Employee_Name", "Name", "Employee_Email", "Email") )

Then you could use the MergedTable as data source within your app.

Note: The PersonList represents your Person List table, the Employees represents your Employees Table.


More details about the RenameColumns function, please check the following article:
