语法
声明
Public Function CalculateMdxObject ( _
tuple As Tuple _
) As MDXValue
用法
Dim instance As Expression
Dim tuple As Tuple
Dim returnValue As MDXValue
returnValue = instance.CalculateMdxObject(tuple)
public MDXValue CalculateMdxObject(
Tuple tuple
)
public:
MDXValue^ CalculateMdxObject(
Tuple^ tuple
)
member CalculateMdxObject :
tuple:Tuple -> MDXValue
public function CalculateMdxObject(
tuple : Tuple
) : MDXValue
参数
- tuple
类型：Microsoft.AnalysisServices.AdomdServer.Tuple
The tuple under which to evaluate the MDX expression.
返回值
类型：Microsoft.AnalysisServices.AdomdServer.MDXValue
An MDXValue that contains the result of the MDX expression.
注释
The type of the MDXValue that is returned can be a non-scalar value, such as a set, a tuple, or a member. The MDXValue that is returned can be cast using one of the To methods, such as ToSet, ToTuple, or ToMember. The MDXValue can also be cast by language-specific casting.
To retrieve a scalar value, such as an integer, double, or string, after evaluating an MDX expression, use the Calculate method.
