Hello,

I am struggling with selecting several group of rows with categorize by data in row :Folder.

My objective is to clean up the data table with full group of "0" or empty cells

For example, i have a data table as such;

Well	Data	Folder
A1	0	20200107 011 3F
A2	0	20200107 011 3F
A3	0	20200107 011 3F
A4	0	20200107 011 3F

How do select and delete off a group of data rows by :Folder, while maintaining the "0" or empty cells that have some values for other :Well in the :Folder

After the clean up, the data table should look like this:

Well	Data	Folder
A1	7544.868	20210104 002 1F
A2	7428.832	20210104 002 1F

Hello,

I think i manage to solve this.. in not very smart way, but it works.
I create an average data column and select the rows that he average == 0
then delete off the rows.

cctable << New Column( "DataAverage",Numeric,Continous,Format( "Best", 9 ),
Formula( Col Mean(:Data, :Folder)));

cctable << Row Selection(Select where( :DataAverage == 0));
cctable << delete rows();
cctable << delete column(column("DataAverage"));

This serve the purpose,
but if anybody have a more robust way of scripting this, do let me know.

Regards
Ashraff

Your code can be simplified. There isn't a need to create the new formula column.

names default to here(1);
cctable = current data table();

cctable << select where(col mean(:data,:folder)==0);
cctable << delete rows;

Thanks Jim,

I knew that there is a more elegant way of structuring the code as you demonstrated.

Thank You!
