dictionary structure.
Syntax
SDAddAttrRelType (Dcb,RelationshipType,RelationshipClass,
Attribute,Status)
Parameters
Dcb Required input; type = DcbType
This parameter passes information about the
dictionary to this intrinsic. It is initialized by
the SDOpen intrinsic.
RelationshipType Required input; type = RelationshipTypeList
This parameter specifies the relationship type to
which an attribute will be added.
RelationshipClass Required input; type = NameOrNumberType
This parameter specifies the class of the
relationship type. Blanks or a 0 may be specified
for this parameter when the entity types specified in
the RelationshipType parameter uniquely identify a
relationship type.
Attribute Required input; type = NameOrNumberType
This parameter specifies the attribute to be added.
Status Output; type = StatusType
This parameter contains information indicating the
success or failure of the intrinsic call. This
information is detailed in Table 3-1, located in
Chapter 3 of this manual.
Discussion
The following restrictions apply when using this intrinsic:
1. Open mode--The dictionary must be opened in Exclusive
Customization mode.
2. Security--The current scope must be either the Dictionary
Administrator scope or a scope with Extend capability.
3. Maximum Quantities--the maximum number of attributes that can be
associated with a relationship type is 128, not including the six
special attributes.
4. An attribute may be assigned only once to a relationship type's
attribute list.
5. The maximum total size of all the attribute list's data values
(not including special attributes) is 2048 bytes. This value is
checked whenever the dictionary is restructured. A description of
special attributes is located in Chapter 3 of the General
Reference Manual (Vol 1).
6. Alias or variable length attributes may not be specified.
7. When the dictionary is restructured, the specified attribute will
be added to every relationship occurrence of the particular
relationship type specified in the intrinsic call. Attribute
value defaults, listed below, depend on the attribute type being
used.
NOTE : These values will be used when no edit exists for the
attribute.
Boolean = false
character = blank characters
floating point = floating point zero
integer = binary zero
