subtracting 1 from a value in the datebase

[harmor19]

I have four fields in the database

mid | title | text | display_order

in the display order coloumn let's say I had values ranging from 1-5
1
2
3
4
5

Now let's say I deleted "2"
After I have deleted it I want a script that will get the values after and subtract "1" from each
1
2
3 (used to be "4")
4 (used to be "5")

[Xenon]

UPDATE tablename SET displayorder = displayorder - 1 WHERE displayorder > 2

I'll try it.

Thanks
