using LIMIT without ORDER BY

[jiangwen jiang]

hi, all:

There's a confusion. I want to get all the data in table t by pages, using
Limit SQL without ORDER BY:
SELECT * FROM t Limit 0,10
SELECT * FROM t Limit 10, 10
...

Is it right without ORDER BY?
Is there any default order in table t, to make suer I can get all data in
the table?

Thanks
Regards!
