Tridion: Replacement for Query.QueryOperator method? - tridion

Query.QueryOperator.AND_Field
We were using this method in Tridion R5.3 VBscript templates and it worked well.
Recently , while migrating to Tridion 2011 SP1, we tried using this method, but it doesn't works.
We understood that this method is depreciated in new tridion versions.
As per some posts in Forum, we also enabled the following lines in CD_Storage_Conf:
<SearchFilter Name="SearchFilter" Class="com.tridion.broker.components.meta.MsSqlSearchFilterHome" defaultStorageId="defaultdb"/>
<Item typeMapping="Query" storageId="defaultdb"/>
The question is, what is replacement of the 'Query.QueryOperator.AND_Field' method? How can we use this filter in C# ?
How to use the Broker Querying Mechanism mentioned in the support API files?
Thanks.

In SDL Tridion 2011 Content Delivery, you create a Query object and add a Criteria object to it using the setCriteria method. The Query object accepts one Criteria object ONLY, but that Criteria object can in turn reference other Criteria objects in a tree structure.
For a good example of creating a Query filter using both AND and OR operators, see Creating a filter in the SDL Tridion 2011 SP1 documentation in SDL LiveContent.
// Schema has ID of either 511 (Article) or 34 (Press Release).
ItemSchemaCriteria IsArticle = new ItemSchemaCriteria(511);
ItemSchemaCriteria IsPressRelease = new ItemSchemaCriteria(34);
Criteria IsArticleOrPressRelease = CriteriaFactory.Or(IsArticle, IsPressRelease);
// Type of the item is 16 (Component).
ItemTypeCriteria IsComponent = new ItemTypeCriteria(16);
// Both of the above conditions must be true
Criteria AllCriteria = CriteriaFactory.And(IsArticleOrPressRelease, IsComponent);
// Add these criteria to a query
Query MyQuery = new Query();
MyQuery.Criteria = AllCriteria;

Dealing with numbers using Spring ExampleMatcher

I am new to Java and Spring, and I am building a sytem using Spring JPA. I am now working on my service and controller classes, and I would like to create a dynamic query. I have created a form, in which the user can enter values in the fields, or leave them blank. I then use example matcher to create an example based on non null fields and query objects in the database that match non null fields of the object.
It is working fine with Strings, and it works ok with numbers, in case the number entered by the user is matching the number in the database. What I would like to ask the community is: how can we, using Spring ExampleMatcher, add logic so that the query relating to numbers is not Select * from Projects where project.return = 10 but for instance Select * from Projects where project.return >=10?
It is a pretty basic question, but I have looked everywhere on the web, and I could not find an answer. All sources that I found said that ExampleMatcher deals only with Strings, but I find that strange that such a powerful system does not have a logic to deal with higherthan / lowerthan number type of criteria.
My code for the example matcher:
ExampleMatcher matcher = ExampleMatcher.matching()
.withIgnoreNullValues()
.withIgnoreCase()
.withIgnorePaths("projectId", "businessPlans", "projectReturn", "projectAddress.addressId")
I would like to add something like:
.withMatcher("projectAmountRaised", IsMoreThan(Long.parseLong()));
What I would have loved to have, but it is deprecated:
public static List getStockDailyRecordCriteria(Date startDate,Date endDate,
Long volume,Session session){
Criteria criteria = session.createCriteria(StockDailyRecord.class);
if(startDate!=null){
criteria.add(Expression.ge("date",startDate));
}
if(endDate!=null){
criteria.add(Expression.le("date",endDate));
}
if(volume!=null){
criteria.add(Expression.ge("volume",volume));
}
criteria.addOrder(Order.asc("date"));
return criteria.list();
}
I am thus looking for something similar... I could create a broad results list from just Strings criteria using ExampleMatcher, and then write my own logic to delete objects that do not fit number criteria, but I am sure there is a more elegant approach.
Thank you a lot for your help, and for your indulgence!
This is how you can use QBE and pageable with additional filters:
ExampleMatcher matcher = UntypedExampleMatcher.matching()
.withIgnoreCase()
.withIgnorePaths("startDate");
MyDao probe = new MyDao()
final Example<MyDao> example = Example.of(probe, matcher);
Query q = new Query(new Criteria().alike(example)).with(pageable);
q.addCriteria(Criteria.where("startDate").gte(probe.getStartDate()));
List<MyDao> list = mongoTemplate.find(q, example.getProbeType(), "COLLECTION_NAME");
PageableExecutionUtils.getPage(list, pageable, () -> mongoTemplate.count(q, example.getProbeType(), "COLLECTION_NAME"));

Returning ItemStats from Tridion UGC

I was wondering if anyone can offer any pointers on this one. I'm trying to return ItemStats from the Tridion UGC web service but I'm getting the following error when trying to bind the results:-
The closed type TridionWebUGC.CDS.ItemStat does not have a corresponding LastRatedDate settable property.
An example of code is:-
WebServiceClient ugcCall2 = new WebServiceClient();
Uri uri = new Uri("http://new.ugc.service/odata.svc");
CDS.ContentDeliveryService cds = new CDS.ContentDeliveryService(uri);
var myItemStats = cds.ItemStats.Where(p => p.PublicationId == 68 && p.Id == 17792 && p.Type==16);
I can get comments and ratings with no problem. E.g.
var myComments = cds.Comments.Where(p => p.ItemId == 17805).OrderBy(p => p.CreationDate);
It's just ItemStats that are giving me an issue. Anybody any ideas?
Thanks
John
Unfortunately, the metadata of the UGC WebService is not correct in regards to the ItemsStats. For you it means that the webservice metadata does not expose the fact that the ItemStat entity contains the LastRatedDate property. This makes your .NET proxies not to be aware of this property and makes your query fail.
To work-around this defect you have two option:
Add to your service the following property: cds.IgnoreMissingProperties = true;. Advantage of this approach is that you're done with it in 2 sec. Disadvantage is that you will not be able to access that property (in case you actually use it);
Modify the proxies generated by Visual Studio and manually add that property to the ItemStat class. Advantage of this approach is that you will be able to access the property from your project. Disadvantage is that it's totally not manageable from the coding point of view, you need to be careful when you upgrade or regenerate the proxies and it's easy to make a mistake while manually adding the property.
Note 1: to access the metadata of your webServer from the browser your can go to /odata.svc/$metadata.
Note 2: on a closer look there are 2 properties missing from the webService metadata: LastRatedDate and LastCommentedDate.
Hope this helps.

StructureGroup Details using the Content Delivery/Broker API

I am trying to get all the structure groups published in a given publication using the PublicationID. I am expecting to get the structure groups with StructureGroupCriteria by passing the Root Structure Group TCM ID but getting page ids (I am expecting SGs).
Now I am trying to loop through the list and get details of each structuregroup. I did not find any API (.net) to get these details and also the API is returning only Pages.
What I have done and working so far using StructureGroupCriteria, returns list of Page IDs instead of SG IDs
PublicationCriteria pubCriteria = new PublicationCriteria(pubID);
// Root StructureGroup TCM ID -- tcm:45-3-4
StructureGroupCriteria sgCriteria = new StructureGroupCriteria("tcm:45-3-4", true);
Criteria allSGsInPub = CriteriaFactory.And(pubCriteria, sgCriteria);
Query allSGs = new Query(allSGsInPub);
string[] sgInfo = allSGs.ExecuteQuery();
Response.Write("Total : " + sgInfo.Length);
foreach (string sgid in sgInfo ) {
// HOW DO I get the Structure Group Details here
//TCMURI sgURI = new TCMURI(sgid);
}
Q # 1 : How to get the all the structuregroups and individual structure group details? (May be something simple, I am not able to find right API).
Q # 2 : How can I get all the structuregroups using ItemTypeCriteria sgCriteria = new ItemTypeCriteria(4); // 4 is SG Item Type .
When I tried this option, the query worked successfully but no results returned. Is this the expected behavior and should we always use StructureGroupCriteria instead of ItemTypeCriteria?
The reason for this approach, I want to avoid using the Root StructureGroup ID which is required with the above code. But at the moment, none of the approaches returning StructureGroup information and I always get Page Information.
Tridion Version: 2011 SP1, .net API.
Note: When I publish I am checking the publish SG info checkbox and published successfully. On Broker DB side, I can see the information on the taxnonomy table as well.
I was playing with Odata service and accidentally I found that I can get all my structure group information from Odata web service.
/cd_webservice/odata.svc/StructureGroups?$filter=PublicationId%20eq%2045
Also, the results are returning child structure groups with a depth parameter.
Just to clarify , using Broker API it is not feasible to get the structure groups (my original question). However, the workaround solution is to use OData Service to get the Structure Groups.
I don't think you will get Structure Groups returned by the Query object.
According to the documentation, when you publish Structure Group information the Structure Group hierarchy is published to the Content Delivery side where it is stored as a taxonomy.
Have you tried using the Taxonomy APIs to get the information you need?

Applying more than one sort on a Tridion broker query

I have a broker query where I need to sort by 2 different fields (using JSP and 2011 SP1)
The API has the method "addSorting" which I am applying.
It appears, however, that the second addSorting call is overwriting the first addSorting call - rather than adding the second sort:
// Sort by Date
CustomMetaKeyColumn customMetaKeyColumnDate = new CustomMetaKeyColumn("date", MetadataType.DATE);
query.addSorting(new SortParameter(customMetaKeyColumnDate, SortParameter.DESCENDING));
// Sort by Owner
CustomMetaKeyColumn customMetaKeyColumnOwner = new CustomMetaKeyColumn("owner", MetadataType.STRING);
query.addSorting(new SortParameter(customMetaKeyColumnOwner, SortParameter.ASCENDING));
They sorts work fine individually.
Is this expected? Is addSorting really a setSorting - where only 1 sort can be specified or am I missing a way to combine 2 sorts?
The addSorting method works just fine. However, it simply does not work for CustomMeta columns!!! There is already a confirmed defect regarding this subject with the following summary: "SortParameter does not work with two metadata fields". This is still an open defect for 2011SP1 and is scheduled to be fixed only for the next release.
Cheers,
Daniel.

Core Service 2011 - Address books

Is it possible to create Audience Manager Address Books using the Core Service (Tridion 2011 SP1)?
(Or automate creating them in any other way - db script, Interop?)
Cheers
There is no Audience Manager functionality in the Core Service; only Content Manager functionality is exposed there.
You can, however, use the public API (Tridion.AudienceManagement.API) on the server to create any item you want. You didn't specify the kind of Address Book you want to create - but I'm going to assume you want a static one to create Contacts in.
Here is some sample code to do that:
StaticAddressBook denmark = new StaticAddressBook();
denmark.Title = "Denmark";
denmark.Key = "DK";
denmark.Save();
If you want to create a Dynamic Address Book instead, you'll need to specify a filter too; let me know if that's the case and I can provide some sample code for that too.
You can use the Tridion.OutboundEmail.ContentManagement namespace. In there is an AddressBook object (or you can use StaticAddressBook depending on the type of AB you want to create). Something like this should work:
AddressBook ab = new AddressBook();
ab.Title = "The title of my new Address Book";
ab.Save();
Looking at the API for StaticAddressBook (it's documented) there's a static method StaticAddressBook.CreateLocalAddressBook that might actually be more relevant in this instance. I'd check it out if I were you ;) You can download the docs from SDLTridionWorld.com
