属性值

A MiningModel that represents the current mining model; null if not applicable.

备注

The return value will be null when called from a Multidimensional Expressions (MDX) query, or as a stored procedure. For more information on the differences between user-defined functions (UDFs) and stored orocedures, see User Defined Functions and Stored Procedures.

示例

In the following example, a UDF is created that returns the node description for a specified node. It uses the current context in which it is being run, retrieves the node from the current mining model (determined by the DMX FROM clause):

public string GetNodeDescription(string nodeUniqueName)
{
    return Context.CurrentMiningModel.GetNodeFromUniqueName(nodeUniqueName).Description;
}
