下一版本的 Microsoft SQL Server 将删除该功能。 请不要在新的开发工作中使用该功能，并尽快修改当前还在使用该功能的应用程序。

The Level interface supports the following properties.

Property	Description
AreMemberKeysUnique	Indicates whether the members of a level are uniquely identified by their member key column
AreMemberNamesUnique	Indicates whether the members of a level are uniquely identified by their member name column
ClassType	Returns an enumeration constant that identifies the specific object type
ColumnSize	The size (in bytes) of members in the level member key column
ColumnType	The data type of the level member key column in an aggregation table
CustomRollUpColumn	Contains the name of the column that contains member-specific rollup instructions
CustomRollUpExpression	Contains a Multidimensional Expressions (MDX) expression used to override the default rollup mode
CustomRollUpPropertiesColumn	Contains the name of the column that contains member-specific rollup properties
Description	The description of the level
EnableAggregations	Determines whether aggregations can be created for a level in a dimension whose AggregationUsage property is set to dimAggUsageCustom
EstimatedSize	The estimated number of members in the level
FromClause	The SQL FROM clause for a level
Grouping	Indicates the type of grouping used by the Analysis server
HideMemberIf	Indicates whether a member should be hidden from client applications
IsDisabled	Indicates whether the level is disabled
IsValid	Indicates whether the level structure is valid
IsVisible	Indicates whether the level is visible to client applications
JoinClause	The SQL JOIN clause for the level
LevelNamingTemplate	Defines how levels in a parent-child hierarchy are named
LevelType	Returns an enumeration constant that identifies the specific type of level
MemberKeyColumn	The name of the column or expression that contains member keys
MemberNameColumn	The name of the column or expression that contains member names
Name	The name of the level
Ordering	Specifies how the level should be ordered
OrderingMemberProperty	Specifies a member property used to determine the ordering of members
OrdinalPosition	Returns the ordinal position of the level in the collection of levels
Parent	Returns a reference to the parent Dimension object
ParentKeyColumn	Identifies the parent of a member in a parent-child hierarchy
RootMemberIf	Determines how the root member or members of a parent-child hierarchy are identified
SkippedLevelsColumn	Identifies the column that holds the number of empty levels between a member and its parent in a parent-child hierarchy
SliceValue	The name of the level member used to define a partition slice
SubClassType	Returns an enumeration constant identifying the subclass type of an object
UnaryOperatorColumn	The name of the column that contains member-specific rollup instructions in the form of mathematical operators
