I need to retrieve a series of data for each id from a table. The data or the row value for the column need to be such that it is the second most recent value. For instance, I have Table- estimate_record as following
Id value last_updated
1 210 10/2018
1 205 11/2018
1 215 12/2018 -- current
I need to get the 205 for that particular id =1
I used Max(value)
, but it's getting 215
which is not right.
If you are running MySQL 8.0, you can do this with window functions:
select *
from (
select t.*, row_number() over(partition by id order by last_updated desc) rn
from mytable t
) t
where rn = 2
In earlier versions, one option uses a subquery:
select t.*
from mytable t
where t.last_updated = (
select t1.last_updated
from mytable t1
where t1.id = t.id
order by t1.last_updated desc
limit 1 offset 1
)
