Data-based queries, Filter, Sum, Avg and Stdev

developers
| |

Sometimes it is not adequate to simply use a single value in a query; you need to consider a combination of values. It might be that this combination is only needed for one or two queries, though, so it is not desirable to calculate and store the result in the cube for all to see. Therefore it is more logical to quickly calculate the result on the fly and although this is then repeated every time the subset is used, it is still the preferred choice. The function Sum, Avg and Stdev are therefore useful for things that are only needed occasionally or by a limited number of users and means that the actual cube is thus smaller and more efficient.


Username and StrToMember

It returns the TM1 username (or Windows domain username depending on the security system being used – for example, “GER\JEREMY”) of the user who runs the query. Note that you may need to give all users Read access to the }Clients dimension and all its elements.


Using TM1 Subsets, TM1Member and TM1SubsetToSet

One of the special features of using MDX with TM1 dimensions is that existing subsets can be used within the query for defining a new subset. This can be useful in allowing a simpler ‘building block’ approach and for not having to repeat the same code over and over again – and having to maintain it.


ToggleDrillState

ToggleDrillState changes the default drill state from a returned set – so if the first query returns a member in a hierarchy rolled up then it will drill it down, or vice versa.

For example,
{[Product].[Customer Lending].Children}


Except and Validating Dimension Hierarchies

developers

The function takes two sets as its mandatory parameters and removes those members in the first set that also exist in the second. In other words it returns only those members that are not in common between the two sets, but note that members that are unique to the second set are not included in the result set.
