Support lower-/upper-case functions
-----------------------------------
Key: JCR-638
URL: http://issues.apache.org/jira/browse/JCR-638
Project: Jackrabbit
Issue Type: New Feature
Components: query
Reporter: Marcel Reutegger
Assigned To: Marcel Reutegger
Priority: Minor
The query languages should support lower- and upper-case functions when
matching property values to string literals.
Example 1: find all nodes with a string property foo with a lower-cased value
that equals 'bar':
In XPath that's:
//*[fn:lower-case(@foo) = 'bar']
An in SQL:
SELECT * FROM nt:base WHERE LOWER(foo) = 'bar'
Example 2: find all nodes with a string property foo with an upper-cased value
that matches '%JCR%'
XPath: //*[jcr:like(fn:upper-case(@foo), '%JCR%')]
SQL: SELECT * FROM nt:base WHERE UPPPER(foo) LIKE '%JCR%'
