Tridion: Replacement for Query.QueryOperator method?

Question

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

Answer 1

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;
