Partition Class

Definition

Namespace:

Microsoft.AnalysisServices.Tabular

Assembly:

Microsoft.AnalysisServices.Tabular.dll

Package:

Microsoft.AnalysisServices v19.87.2

Represents a partition in a table. Partitions define the query against external data sources that return the rowsets of a Table.

Partition()

Create a new instance of the Partition class with default settings.

Properties

Annotations	Gets the collection object of all annotations in the current Partition.
DataCoverageDefinition	A reference to an optional DataCoverageDefinition that provides the hint regarding the data that is covered by the partition.
DataView	Determines which partitions should be selected to run queries against the model. The possible values are as follows. Full (0) - Partitions with DataView set to Default or Full are selected. Sample (1): Partitions with DataView set to Default or Sample are selected. SampleAndFull (2): All partitions are selected. Default (3) - Inherits from the default DataView of the Model object.
Description	The description of the partition, visible to developers at design time and to administrators in management tools, such as SQL Server Management Studio.
ErrorMessage	The string that explains the error state associated with the current object. It is set by the engine only when the state of the object is one of these three values: SemanticError, DependencyError, or EvaluationError.This element applies only to partitions of the type Calculated.
ExtendedProperties	Gets the collection object of all extendedproperties in the current Partition.
IsRemoved	A Boolean specifying whether this object was removed from an object tree. (Inherited from MetadataObject)
Mode	Defines the method for making data available in the partition. Possible values are as follows. Import (0) Data will be imported from a data source. DirectQuery (1) Data will be queried dynamically from a data source. Default (2): Only partitions can use this value. When set, the partition will inherit the DefaultMode of the Model. Push (3): Data will be pushed into the partition. The Mode of a Partition can be set to Default (2), in which case it will inherit its Mode from the DefaultMode of the Model
Model	Gets the Tabular model that contains this object. (Inherited from MetadataObject)
ModifiedTime	The time that the object was last modified.
Name	Gets or Sets the Name of this object.
ObjectType	Gets the type of object. (Inherited from MetadataObject)
Parent	Parent object, null for Model objects.
QueryGroup	QueryGroup associated with the partition.
RefreshedTime	The time that the object was last refreshed.
RetainDataTillForceCalculate	Obsolete. Allows a calculated partition to have data which will not be affected by RefreshCalculate command when there is only data changes.
Source	Gets or sets the PartitionSource object.
SourceType	The type of source used by the Partition. This is either a query against a DataSource, or for calculated tables, an expression.
State	Provides information on the state of the partition. Possible values are as follows. Ready (1): The partition is queryable and has up-to-date data. NoData (3): The partition is queryable but has no data. This state applies only to partitions with a type other than Calculated. CalculationNeeded (4): The partition is not queryable and needs to be refreshed (that is, recalculated) to become functional. This state applies only to partitions of the type Calculated. SemanticError (5): The partition is in an error state because of an invalid expression and is not queryable. This state applies only to partitions of the type Calculated. EvaluationError (6): The partition is in an error state because of an error during expression evaluation. The partition is not queryable. This state applies only to partitions of the type Calculated. DependencyError (7): The partition is in an error state because some of its calculation dependencies are in an error state. The partition is not queryable. This state applies only to partitions of the type Calculated. Incomplete (8): Some parts of the partition have no data, and the partition needs to be refreshed to bring the data in. The partition is queryable. This state applies only to partitions of a type other than Calculated. SyntaxError (9): The partition is in an error state because of a syntax error in its expression. The partition is not queryable. This state applies only to partitions of the type Calculated.
Table	A reference to a Table object that owns this Partition.
