WeeWx version: 4.10.2 DB: SQLite3 What is the best method for recalculating an item in the entire database? Specifically, I want to do this:
signal4 = 1.0 if outTemp < 10.0 else 0.0 So I want the DB update method to look at each record and if the temperature (in that record) is less than 10.0 C then set the signal4 value in that record to 1.0, otherwise, set the signal4 value to 0.0. Do I use wee_database --calc missing? or some other method? There are currently 575,000 records in the database so I really don't want to mess this up. I assume I need to stop WeeWx while doing this?
