The JoinClause property of the Level interface describes how related tables that define the parent Dimension object are linked and takes the form of a SQL JOIN clause.

Applies To:clsAggregationLevel, clsCubeLevel, clsDatabaseLevel, clsPartitionLevel

Data Type

String

Access

Read-only

Notes

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

Exemple

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"
