Hinweise
The JoinClause property of a level returns a nonempty string only when multiple dimension tables are used to define the parent Dimension object of the level. This type of definition results from the snowflake schema
Beispiel
A database contains the following tables:
Sales_Facts
Customer
Product
Product_Class
Promotion
Store
Calendar
This diagram illustrates the relationships of these tables.
Use the following code to return the JoinClause of the level object:
' Assume an object (dsoLevel) of ClassType clsLevel
' and is associated with the Product dimension and
' SKU level
Debug.Print " Level: " & dsoLevel.Name
Debug.Print " Join Clause: " & dsoLevel.JoinClause
The display in the immediate window would show the following:
Level: SKU
Join Clause: "product"."SKU"="product_class"."SKU"
