Subject: [OASIS Issue Tracker] Updated: (ODATA-173) Define Action values for OnDelete element
[ http://tools.oasis-open.org/issues/browse/ODATA-173?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ralf Handl updated ODATA-173:
-----------------------------
Proposal:
Rephrase the second paragraph of section 7.3.8 The edm:OnDelete Element:
If present, the edm:OnDelete element MUST define a value for the Action attribute. The value assigned to the action attribute MUST be
- Cascade, meaning the dependent entities will be deleted if the principal entity is deleted,
- None, meaning a DELETE operation on a principal entity with dependent entities will fail,
- SetNull,meaning all dependent properties THAT DO NOT PARTICIPATE IN OTHER REFERENTIAL CONSTRAINTS will be set to null,
- SetDefault,meaning all dependent properties THAT DO NOT PARTICIPATE IN OTHER REFERENTIAL CONSTRAINTS will be set to their default value.
If no edm:OnDelete element is present, the action taken by the service is not predictable by the client and may vary per entity.

> Key: ODATA-173
> URL: http://tools.oasis-open.org/issues/browse/ODATA-173
> Project: OASIS Open Data Protocol (OData) TC
> Issue Type: Improvement
> Components: OData CSDL
> Affects Versions: V4.0_WD01
> Environment: [Proposed]
> Reporter: Ralf Handl
> Priority: Minor
> Fix For: V4.0_WD01
>
>
> The OnDelete element allows the server telling the client which action it will take on the current entity when a "leading" entity is deleted. Allowed action values are "Cascade" and "None".
> This list of actions is incomplete, the full list of ON DELETE values in standard SQL is
> - NO ACTION
> - CASCADE
> - SET NULL
> TSQL in addition defines the value
> - SET DEFAULT
> The latter would also make sense in the CSDL context as a property can have a default value.
