Ok, then there are also other grouping or sorting effects involved. Unfortunately there is no way to enforce a specific order. The CTE trick you use is just that: a trick and it doesn't always work. So until Firebird supports a list(... Order by...), there is no way to always get a deterministic order.

This forces a sort which overrides any previous order. I don't think there is a solution to this problem except ineffecient and convoluted double querying. Mark
