Create a Cumulative Sum Column in MySQL
- by Kirk
I have a table that looks like this:
id count
1 100
2 50
3 10
I want to add a new column called cumulative_sum, so the table would look like this:
id count cumulative_sum
1 100 100
2 50 150
3 10 160
Is there a MySQL update statement that can do this easily? What's the best way to accomplish this?
