Merge/Concat Data tables in PAD

Posted on by JuanPuelloUSGBC

Hi,

I have two datatable variables and I want to add all the values from DataTable2 to DataTable1. The tables have the same amount of columns. So, let's suppose this:

DataTable1: 2 Columns (Column1 - Column2) - 3 Rows

DataTable2: 2 Columns (Column1 - Column2) - 7 Rows

The expected result that I want is: 2 Columns (Column1 - Column2) - 10 Rows

I know I can achieve this with a for loop or even using Excel to paste the values and read all of them together. But those options don't work for me in my current use-case.

I was doing some research about using custom objects, JSON conversions, etc. but could not find anything useful. Maybe I can use some of the scripting actions available?

Thanks in advance!

Thanks for the answer, but as I mentioned in the topic, I know that I can achieve this using a for loop or using Excel, but I am looking for a more efficient way to do this and also avoid changes in my data (Could happen if using Excel approach)

Then I would do it with a script as you were suggesting.

Before merge:
After merge:

Copy paste action to your PAD flow:

Scripting.RunDotNetScript Language: System.DotNetActionLanguageType.CSharp Script: $'''DT1.Merge(DT2); DT1 = DT1.DefaultView.ToTable();''' @'name:DT1': DataTable1 @'type:DT1': $'''Datatable''' @'direction:DT1': $'''InOut''' @'name:DT2': DataTable2 @'type:DT2': $'''Datatable''' @'direction:DT2': $'''In''' => DataTable1
