Re: [lyo-dev] Query question

[Christopher D Fryett <fryett@xxxxxxxxxx>]

Samuel,

  Thank you for the guidance.  I was able to work around the issue and didn't need to use the setPrefix().  One of the problems obvious is a lack of understanding RTC's OSLC API on my part.

Correction:

queryParams.setWhere("dcterms:type=\"com.ibm.rational.utl.request.type.utlrequest\"");
queryParams.setPrefix("dcterms=<http://purl.org/dc/elements/1.1/>");

Chris,

In your request below, you ask for dc:type and dc:description without defining the dc prefix. I can tell from the URI of the description. If you use a non-standard prefix, you must use oslc.prefix or the provider won't know what you're referring to. It's also a bad idea to use different prefixes for the same namespace (both dcterms and dc in the same request).

For your original request, you have a long query. I would start with something simple to try to get it to work, then build from there. How about

queryParams.setWhere("dc:type=\"com.ibm.rational.utl.request.type.utlrequest\");
queryParams.setPrefix("dcterms=<http://purl.org/dc/elements/1.1/>");

In my RTC repository, the dcterm:type values are short strings like "Defect". You might double-check the values in your oslc.where.

I also see you have spaces before comparison operators in your original query. This isn't allowed per the query syntax.

I did try changing dc to dcterms with no luck.  When I searched google it looked like there may have been an issue with dc:type but no resolution.  Adding setPrefix() is not working either.  I have gone after a specific work item and get the following although it looks like the first item in the select isn't being returned.  When I incorporated the dc:type for the where clause in my original email I get the error I sent before.

These can be difficult to debug. The one thing that stands out to me is you're using the dc prefix in the where clause instead of the usual dcterms. If you define your prefixes using oslc.prefix, does it work?

queryParams.setPrefix("dc=<http://purl.org/dc/elements/1.1/>,rtc_cm=<http://jazz.net/xmlns/prod/jazz/rtc/cm/1.0/>");

Or perhaps just change dc:type to dcterms:type in your call to setWhere().

I have taken the RTC client example and was able to successfully query the specific RTC provider.  Now I am trying to take an existing query and get it working, but the response says unknown attribute.  Is there a better way to debug this.  The information I am trying to retrieve is a name not the ID.  Your insight is greatly appreciated.

queryParams.setWhere("dc:type in [\"com.ibm.rational.utl.request.type.utlrequest\",\"com.ibm.rational.utl.request.type.sdt\",\"com.ibm.rational.utl.request.type.jsrequest\",\"com.ibm.rational.utl.request.type.ttrequest\",\"com.ibm.rational.utl.request.type.em\",\"com.ibm.rational.utl.request.type.cloud_poc\",\"com.ibm.rational.utl.request.type.grt\"] and rtc_cm:com.ibm.rational.utl.request.attrib.client !=\"\" and rtc_cm:com.ibm.rational.utl.request.attrib.client !=\"TBD\" and rtc_cm:com.ibm.rational.utl.request.attrib.client !=\"NA\" and rtc_cm:com.ibm.rational.utl.request.attrib.client !=\"N/A\" and rtc_cm:com.ibm.rational.utl.request.attrib.client !=\"Enablement\" and rtc_cm:com.ibm.rational.utl.request.attrib.client !=\"Several\" and rtc_cm:com.ibm.rational.utl.request.attrib.client !=\"Internal\" and rtc_cm:resolutionDate =\"\"");
queryParams.setSelect("oslc_cm.properties=rtc_cm:com.ibm.rational.utl.request.attrib.client,dcterms:title,dcterms:type,dcterms:description");
