Hey There I’m trying to figure out the sql code for this:

Assuming I have 4 columns:

ID  NAME  EMAIL
1   Mike  mike@mike.com
2   Bob   bob@bob.com
3   Chris
4   Matt

I want to select the last entry not null from email so in this instance it would be looking for bob@bob.com
I tried Coalesce but that seemed to give me values from the column, but not the LAST one entered. MAX I think is only used to ID’s. Any thoughts?

    By joining against a subquery which returns only the MAX(ID). This isn’t necessary in MySQL, but many other RDBMS won’t permit you to include columns other than the aggregate if they are not also in a GROUP BY clause.

    SELECT yourtable.*
FROM
  yourtable
  JOIN (SELECT MAX(ID) AS ID FROM yourtable WHERE EMAIL IS NOT NULL) maxid ON yourtable.ID = maxid.ID

    Note: In either case this only works reliably if your ID is an auto-incrementing column and you have not meddled with it by inserting rows where previous ids had been deleted.
