SQLServer2012 and early.

FROM [PropertySet] left join Object on PropertySet.Owner = Object.Id 
Where (0 <> Object.Direction or 0 <> Object.PresentationType or Object.Id is NULL) AND [PropertySet].[Parent] = @P1 and [PropertySet].[Format] = @P2  
ORDER BY [PropertySet].Sequence',N'@P1 uniqueidentifier,@P2 smallint','0BE0E009-F7B8-11DF-9D71-005056964503',4

Thanks Jos,

Since the behavior of SQL2012 and SQL2014 are different, the results make trouble on our application. Is there any workaround to make the result to be constant?

Regards,
Yi

Thanks for submitting this feedback.

We do not give any guarantees about the sort order of query results beyond the ORDER BY statement. In the absence of an ORDER BY, the order of query results can change at any given time due to changes in the query plan.
