Hello,
I've got a table which containes two date colomns.
The first one is called `date` and the second `update`
In the first one I put the ticket creation date, and on update I add or
change the update value.
So the update colomn does not contain a value until the first update has
been done.
I would like to order the tickets by their last update value. And if
this value does not exist use the date value.
at the moment I use this :
ORDER BY `date` DESC"
and I would like to replace it by something like this :
ORDER (IF `update`!= '' BY UPDATE ELSE BY DATE)
I know this code is completly wrong, just to try and show you what I
need ...
Here is an example of what I want to achieve
num | date | update
-------------------------------------------
1 | 1 |
2 | 10 | 60
3 | 20 |
4 | 30 |
5 | 40 | 90
6 | 50 |
The required result would be :
num | date | update
-------------------------------------------
5 | 40 | 90
2 | 10 | 60
6 | 50 |
4 | 30 |
3 | 20 |
1 | 1 |
Thanks in advance :)
