Subject [jira] Updated: (JCR-923) Support arithmetic Operators on search
Date Fri, 18 May 2007 05:04:16 GMT

     [ https://issues.apache.org/jira/browse/JCR-923?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Jukka Zitting updated JCR-923:

    Affects Version/s:     (was: 1.3)

I guess that at least the stated use case can just as well be achieved by programmatically
calculating the correct right hand side value when creating the query string, so I wouldn't
put high priority on this issue. However, if we ever start supporting more complex XQuery
constructs, then supporting also functions like this would be a nice touch.

>                 Key: JCR-923
>                 URL: https://issues.apache.org/jira/browse/JCR-923
>             Project: Jackrabbit
>          Issue Type: New Feature
>          Components: query
>            Reporter: Helio S. P.
>            Priority: Minor
> The query languages should support arithmetic operators over propertie values.
> Example 1: find all nodes with a date property foo with date value plus some time duration
that is greater than today (or another date propertie):
> In XPath that's:
> //*[op:add-yearMonthDurations(@foo,xs:yearMonthDuration("P3Y3M")) > xs:dateTime('2006-12-31T00:00:00.000Z')]
> it was added 3 years and 3 months in the date value present in propertie foo and made
the comparison during the query.
> The example was based on http://www.w3.org/TR/xquery-operators/#func-add-yearMonthDurations
