Grouping by date

[aaron]

Hi,

I'm reading a csv with a date column.

I need to group all the rows with the same date into a new excel file.

Aaron,

Check into the "modifyRowset" Task.

Basically, you use the full file RowSet as input, then just select the rows you want (matching the date) as output to create a separate RowSet with just those selected rows. Then, write that out to the Excel.

Thanks.

Is there a way to get distinct values of a column? Or do I have to loop through it first, write it on another file and then read that file and process etc.

I'm not sure what you mean ...

If you only want certain columns from the original file, then the "modifyRowset" will allow you to combine, add, remove columns as you read it.

Thanks, you're right I don't need the distinct method.

When I'm writing to excel, even though i'm passing a single row, it's writing all the dataset in one go. Is there a way to write one row at a time?

Code: Select all
