i see a lot of variation out there on this subject. some people are
using varchar(64), some varchar(32), and some other non-base2 widths.
what is the proper width? i count 36 characters below, including the
four dashes.
mysql> select uuid();
+--------------------------------------+
| uuid() |
+--------------------------------------+
| 8ce826a8-2122-1028-88b7-09e76b61a517 |
+--------------------------------------+
1 row in set (0.00 sec)
are there times when the uuid() function produces output of a longer or
shorter length than 36 characters?
thanks.
