Home -> Community -> Mailing Lists -> Oracle-L -> Re: question about ordering in a table
Obviously the official line is "ordering of results is unpredictable without an order by clause". An easy way to upset the order of results I believe is to add a parallel setting to the table - then you can have multiple reads occuring at once and I'm not sure how results are merged.
At the end of the day you just shouldn't trust it I guess - depending on how critical the order is.

Please respond to
ORACLE-L
If I have a table that does not have any indexes or keys. If I insert 10 records. Will there ever be a case that when I do a select on that table without an 'order by' clause that the result set will return in a different order? Assume the table is read only. No DML is performed on it.
So I insert
1
2
3
4
5
6
7
8
9
10
I do select * from table; Will the data always be returned in that order?
