[Sedna-discussion] Sedna Query
I have two issues that I am attempting to resolve - but have been unable to
produce a working fix for my needs.
1. Is there a function available within Sedna which would allow me to Query a
collection for recently updated XML based on a timestamp?
2. I have a basic request like this:
for $sp in collection('dev.openzis.testarea')
where $sp/StudentPersonal/Title1 = 'No'
return $sp
This simple returns multiple XML objects in a string. To process this request
against a setup of 86,000 XML records
takes some time. To speed up the request I have created a simple
index-scan('Title1', 'No', 'EQ') - however just
creating the index-scan does not speed up my original request.
Q: Must I connect the index-scan to the request above? How might that look?
Can an Index-Scan have multiple elements?
Thanks for your time

Re: [Sedna-discussion] Fwd: Use of several collections in a database
Hi Luca,
I do have another question though : Let's say I have a collection named
Hosts. Inside this collection, I put custom Java objects with the method
above. My question is this : can I use XQuery to search the data from these
objects? And if it is possible, how can I write the actual query?
Let us say my custom object (Host) includes a hostname (String) and the
free space on it (long). I'd like to get, say, the name of the host with the
most free space. The problem is that I don't know the name of the xml tags
used to store the data, since the actual xml was written by the API method.
Isn't there a query that will give me the tags in a collection?
1. To view structure (schema) of your database or collection or document
query one of the following system documents (
http://modis.ispras.ru/sedna/progguide/ProgGuidesu8.html#x14-570002.5.6):
- $schema document – descriptive schema of all documents and
collections with
some schema-related information;
- $schema_name document – the descriptive schema of the document
or collection
named name;
For example, run se_term, and execute doc('$schema_test') to get structure
of the 'test' document/collection.
2. How do you store your resource? Please give us snippet of code - it's
very hard to understand even which one API do you use (XML:DB, XQJ, native
Sedna Java API).

Re: [Sedna-discussion] Sedna Xinclude
Hi Veeru, Do we have xinclude support in sedna No, Sedna doesn't process XInclude instructions. You need to include documents on the application level (with some tools or/and libraries) before bulk load them into Sedna.

Hi Christopher,
1. Is there a function available within Sedna which would allow me to Query
a collection for recently updated XML based on a timestamp?
Do you mean something like: get all documents which were updated in 2
hours? No, Sedna doesn't track updates timestamps.
Q: Must I connect the index-scan to the request above? How might that look?
Can an Index-Scan have multiple elements?
index-scan('Title1', 'No', 'EQ')
should return the same result as your initial query. Send us create index
statement you executed, if that query doesn't work properly.

Re: [Sedna-discussion] Sedna Query
Christopher,
There's nothing stopping you from creating documents, where on ingestion
time you include a time stamp in an element which can be indexed.
e.g.
doc
data /
/doc
becomes:
doc
data /
timestamp2011-04-12T23:39:43.293/timestamp
/doc
Regards,
Charles
