Hi,
I have a table with the following columns:
symbol
date
value
I want to select all the symbols (grouping by symbols) between 2 specified
dates, and calculate the percent of change for each symbol.
The percent of change is (the value from the last date of the symbol - the
value from the first date) / the value from the first date.
For example I have:
SMB1, 2007-01-01, 1000
SMB1, 2007-03-15, 2100
SMB1, 2007-10-10, 1300
... (other symbols)
And the result of the select should be:
SMB1, 0.3
Is it possible to do this with an MySQL query?
Thank you.
Octavian
