I found a piece of code in our cloud that was written by someone in the past, and I don't know what it does (I have no developer experience).
%%[ if Not Empty(@zip) Set @rows = LookupRows("ShipTimes", "zip", @zip) if RowCount(@rows) == 1 then set @row = row(rows,1) set @city = Field(@row, "city") set @state = Field(@row, "state") endif endif ]%%
and another one:
SELECT l.ListName, de.SUBKey, l.[Status] from [<de_name>] de Join [_listsubscribers] l ON de.SubscriberKey = l.Subscriberkey where l.listname = '<List name>'
Do any of you have any idea what are the codes supposed to do?
