Sequence Class

This class represents the SQL Server Sequence. A sequence is a user-defined schema bound object that generates a sequence of numeric values according to the specification with which the sequence was created. The sequence of numeric values is generated in an ascending or descending order at a defined interval and can be configured to restart (cycle) when exhausted. Sequences, unlike identity columns, are not associated with specific tables. Applications refer to a sequence object to retrieve its next value. The relationship between sequences and tables is controlled by the application. User applications can reference a sequence object and coordinate the values across multiple rows and tables.

  NameDescription
Public propertyCacheSizeGets or sets the number of sequence values to be cached.
Public propertyCreateDateGets a DateTime representing the date and time when the sequence was created.
Public propertyCurrentValueGets the Object which represents the current value of the Sequence
Public propertyDataTypeGets or sets the [Microsoft.SqlServer.Management.Smo.DataType] of this sequence.
Public propertyDateLastModifiedGet the DateTime representing the date and time the sequence was last modified.
Public propertyEventsGets the SequenceEvents object associated with this sequence.
Public propertyExtendedPropertiesRepresents a collection of ExtendedProperty objects. Each ExtendedProperty object represents an extended property for the ExtendedPropertyCollection object.
Public propertyIDGets the ID value that uniquely identifies the sequence.
Public propertyIncrementValueGets or sets the object that represents the increment value for the sequence.
Public propertyIsCycleEnabledGets or sets a Boolean that specifies whether the sequence object should restart from the minimum value (or maximum for descending sequence objects) or throw an exception when its minimum or maximum value is exceeded.
Public propertyIsExhaustedGets a Boolean which indicates whether the sequence is exhausted.
Public propertyIsSchemaOwnedGets a Boolean value that indicates whether the Sequence object is owned by a schema.
Public propertyMaxValueGets or sets an Object that specifies the upper bound for the sequence object. The default maximum value for a new sequence object is the maximum value of the data type of the sequence object.
Public propertyMinValueGets or sets an Object that specifies the lower bound for the sequence object. The default minimum value for a new sequence object is the minimum value of the data type of the sequence object.
Public propertyNameGets or sets the name of the sequence. (Overrides ScriptSchemaObjectBase.Name.)
Public propertyOwnerGets the name of the owner of the Sequence object.
Public propertyParentGets the Database object that is the parent of the Sequence object.
Public propertyPropertiesGets a collection of Property objects that represent the object properties. (Inherited from SqlSmoObject.)
Public propertySchemaGets or sets a String which contains the name of the schema which owns the Sequence. (Overrides ScriptSchemaObjectBase.Schema.)
Public propertySequenceCacheTypeGets or sets a SequenceCacheType which indicates how the sequence is cached.
Public propertyStartValueGets or sets a Object which represents the starting value of the sequence.
Public propertyStateGets the state of the referenced object. (Inherited from SmoObjectBase.)
Public propertyUrnGets the Uniform Resource Name (URN) address value that uniquely identifies the object. (Inherited from SqlSmoObject.)
Public propertyUserDataGets or sets user-defined data associated with the referenced object. (Inherited from SmoObjectBase.)
