So it feels like I need to own them flip off bind variable peeking for this query only. Else rewrite as ‘literal’ – but unsure how achievable this tends to be.
As typical you should start by developing a SSAS project and introducing data supply and facts supply see. I've utilized the vTargetMail watch of AdventureworkDW database as the datasource see. Then pick out make mining composition by suitable clicking mining construction from the Solution Explorer. After choosing clustering as the info mining algorithm, it is possible to choose the attributes you think that most appropriate for the situation. Right after generating the information mining construction and processing it you may get the clusters and their associations as revealed in under impression. This is certainly situation , ten clusters have been made. These clusters are joined by a line which suggests the connection in between Individuals two clusters.
