Subject: [OASIS Issue Tracker] (ODATA-1105) Simplify selection of properties of complex type
[ https://issues.oasis-open.org/browse/ODATA-1105?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Michael Pizzo updated ODATA-1105: --------------------------------- Proposal: Harmonize syntax for complex properties within $select with syntax for navigation properties within $expand: - complex property can be followed by parentheses containing - $expand nested in $select. - $select with same recursive syntax - $compute to place computed properties within the complex type - for collection-valued complex properties also $filter, $search, $count, $orderby, $skip, and $top within the parentheses Extended $select syntax also allowed for $select nested within $expand. was: Harmonize syntax for complex properties within $select with syntax for navigation properties within $expand: - collection-valued complex or primitive property can be followed by /$count to select the count of the collection - /$count segment can be followed by parentheses containing $filter or $search to count only matching members of the collection - complex property can be followed by parentheses containing - $select with same recursive syntax - $compute to place computed properties within the complex type - for collection-valued complex properties also $filter, $search, $count, $orderby, $skip, and $top within the parentheses Extended $select syntax also allowed for $select nested within $expand. Do not allow $expand nested in $select. > Simplify selection of properties of complex type > ------------------------------------------------ > > Key: ODATA-1105 > URL: https://issues.oasis-open.org/browse/ODATA-1105 > Project: OASIS Open Data Protocol (OData) TC > Issue Type: Bug > Components: URL Conventions > Affects Versions: V4.01_CSD02 > Environment: Proposed > Reporter: Michael Pizzo > Fix For: V4.01_CS01 > > > Currently, properties of complex types are individually selected, as in: > $select=Name,Address/City,Address/State,Address/Zip > We could simplify the syntax for selecting individual properties of a complex type, similar to expand options. Something like: > $select=Name, Address($select=City,State,Zip) > or > $select=Name, Address(City,State,Zip) > The first syntax would support adding the ability, for example, to $filter or $sort a collection of complex types. > We could put $compute (or an inline expression) in the $select in as a scoped value (couldn't be used in filter/sort). > Putting $expand in $select brings in all the issues of combining $expand and $select and results in two ways of doing expand. -- This message was sent by Atlassian JIRA (v6.2.2#6258)
