Properties

Database

The database that contains the sequence.

IncrementBy

The amount to increment by to generate the next value in, the sequence, or null if not set.

IsCyclic

Indicates whether or not the sequence will start over when the max value is reached, or null if not set.

IsReadOnly

Indicates whether the current object is read-only.

(Inherited from AnnotatableBase)
Item[String]

Gets the value annotation with the given name, returning null if it does not exist.

(Inherited from Annotatable)
MaxValue

The maximum value supported by the sequence, or null if not set.

MinValue

The minimum value supported by the sequence, or null if not set.

Name

The sequence name.

Schema

The schema that contains the sequence, or null to use the default schema.

StartValue

The start value for the sequence, or null if not set.

StoreType

The database/store type of the sequence, or null if not set.
