Hello everyone ,
I have to remove duplicates only from a specific column so that my Bot does not pick the repeated value in the next iteration. Currently I am using Invoice key and Unique reference to login to an application make a search . The Invoice Key has duplicates whereas Unique reference doesn’t have duplicates. How can I eliminate duplicates only from Invoice Key column keeping the actual Data table structure intact without deleting other rows in the Data table ?
Any sort of input would be much appreciated . Thanks !
@chenderson-Good morning . The mentioned post would be helpful if I want to remove all the other row values as well. In my current scenario I do not want to remove values from other rows. I just want to delete duplicates from a Column so that it does not effect rest of the other values from my Data table. Does that give you an idea of what I actually needed?
Hi @chenderson- in my scenario only out of 50 columns, only one Column is having duplicate values and I want to delete/empty those cells which have repeated values from that specific column only . How can i do that is what I meant to ask.
so you have a datatable with 50 rows and 50 column. There is a duplicate value in column 1 rows 1 and row 2. So you want the output to have 50 rows, but the value in row 2, column 1 should be blank? Or did you want to completely remove row 2 altogether?
Then in a for each loop, change the TypeArgument to DataRow.
Assign row.item(“YourColumnName”) = string.empty
I have tested it and this will work. It iterates through the collection of datarows directly from your datatable. Your output is still the original datatable. Here is a sample .xaml Shailesh123.xaml (9.4 KB)
EDIT: I realized after posting that this will only work if there are only 2 rows that are duplicated. If it is 3+ it will still leave duplicates. This can be resolved by putting it all within a while loop, or updating the assign activity to get IEnumerable<iEnumberable<datarow>> type and doubling the for each loop. I attached the updated .xaml showing the second method here: Shailesh123-updated.xaml (10.7 KB)
@Dave Hello Dave it did partially solve my problem . But now I want to read the relevant value of row 2 . For example : if Row1 has a Key I want to basically read Row2 as a Value for Row1.
So that when I pass Row1 value as a variable , I can read Row2 value as another variable which is equal to row1 .
Do you always want the row below it? If so, do it in a for each row loop.
For each row in dt
If (put your condition here to check for key value)
Assign row.item("YourColumnName") = dt.Rows(dt.rows.indexof(row)+1).item("YourColumnName").ToString
This will loop through the entire table and assign the value from the row below it into the current row for the column specified. Keep in mind if the last row meets your if condition it will throw an error, because there is no row below it to grab the value from
