JoinClause (clsColumn)
[!附註]
下一版的 Microsoft SQL Server 將不再提供此功能。請勿在新的開發工作中使用此功能，並且儘速修改使用此功能的應用程式。
The JoinClause property of an object of ClassType clsColumn specifies the JOIN clause of the SQL query that returns a nested table for the column. This property applies to columns that belong to mining model objects of SubClassType sbclsRegular.
Data Type
String
Access
Read/write
備註
This property is read/write only for nested columns (columns of SubClassType sbclsNested). For regular columns (columns of SubClassType sbclsRegular), this property is read-only and returns the JoinClause property of the column's parent object.
Examples
Creating a Nested Column
The following example creates a nested column and establishes two joins to the parent columns based on the SalesRep column and the Product column:
Set dsoNestedCol = dsoDmm.Columns.AddNew("Products", sbclsNested)
dsoNestedCol.FromClause = "Sales, SalesReps, Products"
dsoNestedCol.JoinClause = "Sales.SalesRep = SalesReps.Name AND Sales.Product = Products.Product"
dsoNestedCol.Filter = ""
