Query: how to group data by months from a text file
...092007 22.38 24.72 18.80
22092007 23.94 24.73 20.40
23092007 25.33 25.12 22.60
24092007 24.91 22.46 21.40
25092007 23.52 25.00 21.70
26092007 20.50 22.29 18.80
...
where in the first column there is the date (DDMMYYYY), in the last three columns data.
I should divide these data by months (example:Jan07, Feb07, ..., Dec07, Jan08, ...), where the start and the end can change depending on the file.
Could somebody give me some good hints about it?
thank you
Stefano
