속성 값

유형: System. . :: . .Int64
An integer that contains the holdout seed. If 0, a hash of the ID of the MiningStructure is used as the seed. The default value is 0.

주의

Partitioning is random and data dependent. To ensure that a particular partition can be repeated, you must specify a seed.

Note   To enable creation of a testing data set, the CacheMode property of the mining structure must be set to the default value, KeepTrainingCases.

[!참고]

SQL Server 2005 does not support creation of holdout partitions on a mining structure. You cannot use HoldoutSeed with a mining structure that is stored in an instance of SQL Server 2005 Analysis Services.
