Question

I have a field in my table that contains numbers for instance: 7121968 – what I would like to do is add a . before the last four and before the last 6 digits so that it looks like: 7.12.1968.
I can use substring to just show the last 4 digits etc – is what i am trying to do possible using substring and if so could someeone point me in the right direction? thanks.

Do like this:

SELECT CONCAT(SUBSTRING(<column>, 1, 1), '.', SUBSTRING(<column>, 2, 2), '.', SUBSTRING(<column>, 4)) FROM <table>
