I can't find the relation between those 2 columns, can you guys help me?
It seems possible to identify an approximate relation between date and SecondValueA. Check an example:
declare @date as datetime2 = cast('2021-03-29 14:12:37.163' as datetime2) declare @secondValueA bigint declare @x1 datetime2 = cast('2021-03-29 14:10:07.159' as datetime2) declare @x2 datetime2 = cast('2021-03-29 14:15:37.162' as datetime2) declare @y1 bigint = cast(-232845330 as bigint) declare @y2 bigint = cast(-1227785454 as bigint) + cast(0x100000000 as bigint) set @secondValueA = @y1 + (@y2 - @y1) * datediff_big(mcs, @x1, @date) / datediff_big(mcs, @x1, @x2) if @secondValueA > 0x7FFFFFFF set @secondValueA -= cast(0x100000000 as bigint) select @date as [date], @secondValueA as SecondValueA
Every 30 seconds SecondvalueA increases by about 299930364：
select 67219244-(-2328453330) select 367172064-67219244 select 667144628-367172064 select 967261916-667144628 select 1267192280-967261916
I'm not sure if the relationship between the two columns you are looking for is a direct link between the data between the two columns.
