how to the find difference between dates ( in days ) that are in one column?

sarahi6

I am currently trying to figure out the days between each customers transaction. I know you can use the DATEDIFF function but what if my dates are all in one column?

Any suggestions?

can you try:

DATEDIFF(`Transaction Date`,LAG(`Transaction Date`,1) OVER (PARTITION BY `Customer ID` ORDER BY `Transaction Date`))

I'm not sure if LAG() works in beastmode or not
