If I have a number of records returned from a query, and the resut set has an order by clause, what happens when 2 or more rows meet the same criteria

for example

ColA Colb ColC
A 1 Z
B 1 Y
C 2 X
C 2 W

If I Order By ColA, ColB then which way round would the 2 C rows be returned?

I have a feeling they will be returned in the order they are read from the source table but I just want to confirm it.

Cheers.

The sequence is undefined. It will probably/usually be in the sequence the rows were created, or based on an index, but if the sequence matters you need to ensure that your order by clause includes all appropriate fields.
