HI, New to SQlite, I have a SQlite single database with 2 data columns. The data comes in at various time and so has nulls. I wish to read the 2 columns IP_24_Temperature and IP_24_Humidity I do not want any Nulls as I want to make a graph from this data. What are the commands to do the above ? Example ... IP_24_Temperature IP_24_Humidity 16.5 Null Null Null Null Null 16.8 58 Null Null Null Null Null Null Null 60 Null Null 16.5 61 What I require is ... IP_24_Temperature IP_24_Humidity 16.5 0 16.5 0 16.5 0 16.8 58 16.8 58 16.8 58 16.8 58 16.8 60 16.8 60 16.5 61 ...... etc Thanks Gaz
