sql - MySQL - rand from the defined values -


i'm trying insert random values tables. don't want make new values totally random (like eg: random numbers or characters),i want take random value set of values defined earlier. example: defined values: xyz, abc, edf random value: abc

i programming languages it's easy, in sql don't know, how store defined values , how take random value.

put random values in table.

then, can insert them 1 @ time doing:

insert tables(val)     select val     randomtable     order rand()     limit 1 

the order rand() limit 1 chooses random value list.
