Search in Tamino

I have “Element simple” with type “xs:string” in my base. His name is “EntryID”. his value is “00”.
I can not find it with request: …[EntryID=“00”].
But if value is on range “01” - “99” - all right.
And if value is “0” and
request is …[EntryID=“0”] - all right two.
Is it right?

Hello CBH,

is your problem occurring with the XML:DB API, or is it a more general problem?

Please post the Tamino Schema that you are using for your documents, then we will investigate the problem further.

Thanks,
Trevor.

Hello,Trevor.
My mind - this problem is more general. May be it linked with data-compression. Althoug, compression for index…
My schema:

Hello CBH,

unfortunately, I can’t recreate the problem you are experiencing!

Using the schema you posted and this instance:
   <?xml version="1.0" encoding="UTF-8"?>

      00
      xXx
      xXx
      <Date_Time>Today</Date_Time>
      A
      B
      C
      http://www.softwareag.com/


The query /DCMXML[EntryID=“00”] returns the document correctly:
   <?xml version="1.0" encoding="iso-8859-1"?>
   <ino:response xmlns:ino=“http://namespaces.softwareag.com/tamino/response2” xmlns:xql=“http://metalab.unc.edu/xql/"><BR>      <xql:query>/DCMXML[EntryID="00”]</xql:query>
      <ino:message ino:returnvalue=“0”>
         ino:messagelineXQL Request processing</ino:messageline>
      </ino:message>
      xql:result

            00
            xXx
            xXx
            <Date_Time>Today</Date_Time>
            A
            B
            C
            http://www.softwareag.com/

      </xql:result>
      <ino:message ino:returnvalue=“0”>
         ino:messagelineXQL Request processed</ino:messageline>
      </ino:message>
   </ino:response>

I tested this using Tamino 3.1.2.1 and querying from Internet Explorer.

Could you please send details of your documents and how you are submitting the query (Browser, API, etc.)?

An interesting test for you to try would be to execute the query using ino:explain().
For example: _xql=ino:explain(/DCMXML[EntryID=“00”])

This gives me the response:
   <?xml version="1.0" encoding="iso-8859-1"?>
   <ino:response xmlns:ino=“http://namespaces.softwareag.com/tamino/response2” xmlns:xql=“http://metalab.unc.edu/xql/"><BR>      <xql:query>ino:explain(/DCMXML[EntryID="00”])</xql:query>
      <ino:message ino:returnvalue=“0”>
         ino:messagelineXQL Request processing</ino:messageline>
      </ino:message>
      xql:result
         <ino:explanation ino:preselection=“FALSE” ino:postprocessing=“TRUE”/>
      </xql:result>
      <ino:message ino:returnvalue=“0”>
         ino:messagelineXQL Request processed</ino:messageline>
      </ino:message>
   </ino:response>

Which is correct for the schema given - preselection is “FALSE” because EntryID doesn’t have an index, thus postprocessing is “TRUE” because the post processor is used to find the result.
Perhaps the response will show you something interesting on your system.

I hope that helps,
Trevor.

Excuse me. It is my bug.
