M2 and dim3 full#
A full explanation about Auto-Exists is here (look under ‘Cube Space and Auto-Exists’ section). It is basically the MDX Exists function, but automatically put there by SSAS. DiM3 0.06 1.85 5.11 6.55 Netherlands DiM2 1.67 7.56 12.58 15.11 DiM3 0.75. A backgrounder on Auto-Exists is here (by Christian Wade, look under Fact Dimension section) and here (by Teo Lachev). SSAS detects that the set it needs to apply Auto-Exists to, can be nicely split into parts. living space (6.5 m2 vs 3 m2 per animal) on critical aspects of cow biology. It is because of Auto-Exists, as Mosha pointed out here, i.e. If we put the attribute from the same dimension together, SSAS only return the tuples that actually exist, rather than returning all possible tuples. While this order of attribute might not be the one that suit the user, it is the one that SSAS likes. In this last MDX query, you’ll notice that Dim3’s attributes are put together and Dim4’s attributes are put together whereas on the first MDX query, the attributes are sandwiched. The last MDX does not result in the 4.2 billion error message. It is very interesting to learn that when we move the attributes about, the error goes away. The non empty cross join function fails, as Microsoft explained here, because the ‘optimized algorithm for non empty’ can’t handle dimension security on the measures, so SSAS uses the default algorithm. For this error to occur the user must belong to a role that has dimensional security. The error occurred because the query results in more than 4.2 billion tuples and therefore the non empty function fails. So, I guess there's no real point in calling them another third, to be stacked, as the notes will make another named chord. This error happens on both SSAS 20 (I don’t know if it happens on R2 or 2k). A dim3 ends up as the same note as a M2 (in sound, in 12et), while an aug3 ends up, in similar manner, as P4. when we have more than 5 attributes on the rows or columns, and only when we use the non empty function. It seems that this error only happens on complex MDX queries, i.e. Oddly enough, when you reorder the attributes on rows or columns the error goes away. It does not matter where we are running the query from, SSMS, BIDS, ProClarity, or MDX Studio, it always returns the same error message. it always happens every time we run that MDX query. The expression contains a function that cannot operate on a set with more than 4,294,967,296 tuples. When we run a complex MDX query, sometimes SSAS returns the following error message: By using Matrix Exponentiation method over fibonacci -> O (logN) I have written the O (logn) solution in javascript using matrix exponentiation but no use because, ended up with result of infinity as it exceeds Number.MaxValue of js. The fact that moving the attributes about solves the problem really amazed me so I’ll detail it out a little bit.
