Debugging Attribute Relationships in the ROLAP Basis

I guess that this is quite obvious and could as well be published in our ROLAP blog, but just for the sake of completeness:

The following SQL-Statement lists all values of a source attribute

src

in your dimension source table/view

dim

which violate an attribute relationship (path) to a destination attribute

dest

.

select src from dim group by src having count(distinct dest)>1

Extending this a bit delivers all the bad rows:

select * from dim where src in (select src from dim group by src having count(distinct dest)>1)
