MySQL generated UID
Solution 1
If you don't want globally unique IDs, just a unique ID (a different number each time you call it), then you can create a table with only an integer auto_increment non-null column and issue the following two queries:
INSERT INTO tbl1 SET col1 = NULL;
SELECT LAST_INSERT_ID();
To start the number at something other than 1, for example, to start at 10 digits, set it like this:
ALTER TABLE tbl1 AUTO_INCREMENT = 1000000000
Solution 2
MySQL has a function for that. Try:
SELECT UUID();

I am coding a messaging system and I don't want to have short IDs shown, is there any way that MySQL can generate a UID which is unique as UID suggests?
I need to know how I can do this with ONLY MySQL, no PHP, JavaScript or anything else, just MySQL, if not possible, fine, I just want to make sure.
Sorry, I should have made it more clear when I say UID I just mean "Unique ID" but I need it in a multidigit number only, e.g. 914888629, 3890692140
