[OASIS Issues Tracker <workgroup_mailer@lists.oasis-open.org>]

     [ http://tools.oasis-open.org/issues/browse/ODATA-72?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ralf Handl updated ODATA-72:
----------------------------

       Proposal: 
Add sections 

5.1.1.5 Lambda Operators
OData defines two operators that evaluate a boolean expression on a collection of entities or complex type instances. Both must be prepended with a navigation path that identifies a collection.

5.1.1.5.1 any
The any operator applies a boolean expression to each member of a collection and evaluates to true if the expression is true for any member of the collection. As a special case the boolean expression may be empty, in which the any operator evaluates to true if the collection is not empty.

For example:

http://services.odata.org/Northwind/Northwind.svc/Orders?$filter=Order_Details/any(d:d/Quantity gt 10)

Returns all Orders that have any Orderlines with a Quantity greater than 10.

5.1.1.5.2 all
The all operator applies a boolean expression to each member of a collection and evaluates to true if the expression is true for all members of the collection.

For example:

http://services.odata.org/Northwind/Northwind.svc/Orders?$filter=Order_Details/all(d:d/Quantity gt 10)

Returns all Orders that have only Orderlines with a Quantity greater than 10.
    Environment: [Proposed]
