Hello!
Somewhere the users made mistakes on prices (stock).
I need to search for big differences between values.
For example:
20
21
21,5
30
28
..
46392 <-
46392 <-
But it could be:
42300
43100
44000
43800
65000 <-
42100
Human eye could locate these values, but there we need to check 30.000
articles and 450.000 values.
Do you have any idea, how to this with SQL?
In most cases the first values are ok, the second interval (after a date)
it could be wrong...
I don't know how to define the solution, but I think PGSQL have intelligent
solution for this problem.
We need to search for elements have bigger value like base price *
tolerance.
But the base price is calculated dynamically from the lower values... The
tolerance is lower on highest base prices.
Thank you for any help!
Best regards dd
