Обсуждение: list non alphanumeric
Hi
Firstly let me mention I am a noob to postgres,DB and sql anyway, I have a column with First names and need to list names that have non-alphanumeric characters in them like + or * and the list goes on. I did google a bit and tried:
select * from TABLE where first_name not like '%[a-z0-9]%';
However the above shows all the entries in that column and if I change it to Like, which should show all the entries it shows nothing.
e.g of my goal:
Column
Bob
Jane+
Harry*
John
Mike
Larry
My query should output
Jane+
Harry*

you'll probably have to use a regex for that.
something like... (my regex is really rusty)
... WHERE first_name !~ '^[a-z0-9]*$';

well, at least one of those has a space inline, you didn't say that was acceptable, just a-z0-9
and of course, upper and lower case, so you probably should use [A-Za-z0-9 ] (note the space before the close bracket)

Sorry guys I should have mention spaces, I did but it was a bit late. Anyway that [A-Za-z0-9 ] worked thanks John.
