Properties
Name Datatype Opt ? Notes Domain Default Value
CACHE_VALUE NUMBER(38, 0) Y Specifies a pre-allocation of sequence numbers that can be cached in memory.
Prompt: Cache Value
COMPLETE_FLAG VARCHAR2(1) N Indicates whether the definition of the database object is complete and ready to be used by the generators
Prompt: Complete ?
Uppercase
Defined on DOI supertype
YESNO Y
CYCLE VARCHAR2(1) N Indicates whether or not the sequence is cyclical
Prompt: Cycle ?
Uppercase
YESNO N
GLOBAL_SYNONYM_NAME VARCHAR2(30) Y Name to be used by Server Generator when creating synonyms for this object
Prompt: Global Synonym Name
Uppercase
INCREMENT_VALUE NUMBER(38, 0) Y The number by which the sequence is incremented
Prompt: Increment
MAXIMUM_VALUE NUMBER(38, 0) Y Specifies the maximum value for the sequence
Prompt: Maximum
MINIMUM_VALUE NUMBER(38, 0) Y Specifies the minimum value the sequence will generate
Prompt: Minimum
OBJECT_IMPLEMENTATION_TYPE VARCHAR2(3) N Sub-type discriminator. Internal property indicating whether the DB_OBJECT_IMPLEMENTATION is a TABLE_IMPLEMENTATION (TBI), VIEW_IMPLEMENTATION (VWI), SNAPSHOT_IMPLEMENTATION (SNI), SEQUENCE_IMPLEMENTATION (SQI) etc
Not displayed
Uppercase
System maintained
Not updatable by user
Defined on DOI supertype
OBJECT_IMPLEMENTATION_TYPE
SCOPE VARCHAR2(8) N Scope of visibility of the database object, used by the Server Generator to determine when database links and synonyms need to be created

START_VALUE NUMBER(38, 0) Y Specifies the first sequence number to be created
Prompt: Start
PARENT_IVID NUMBER(38, 0) Y Internal use only. Exists on "secondary" element types from a versioning viewpoint. Contains the IVID of the primary element type (not necessarily a PAC) forming the basis of the "versionable object" to which this element type belongs
Not displayed
System maintained
Updatable only if null
Defined on SAC supertype
PAC_REFERENCE NUMBER(38, 0) Y Internal use only. Exists on "secondary" element types from a structural viewpoint. Contains the IRID of the PAC forming the basis of the "logical object" to which this element type belongs

The following 'standard' properties are also inherited by all element types:
  • ID
  • IRID
  • IVID
  • ELEMENT_TYPE_NAME
  • DATE_CREATED
  • CREATED_BY
  • DATE_CHANGED
  • CHANGED_BY
  • NUMBER_OF_TIMES_MODIFIED
  • TYPES

Other element types that reference SEQUENCE_IMPLEMENTATION:


Note:

  • All properties are displayed and updatable by the user unless indicated otherwise
  • All reference properties are displayed and transferable unless indicated otherwise
  • All domains are enforced unless indicated otherwise
  • All properties and reference properties are defined on this element type unless indicated as inherited from a supertype
