    A QueryTag creates a ResultCache object and initializes it with the MDX query. Example:

 select
   {[Measures].[Unit Sales], [Measures].[Store Cost]} on columns,
   CrossJoin(
     { [Promotion Media].[Radio],
       [Promotion Media].[TV],
       [Promotion Media].[Sunday Paper],

     [Product].[Drink].children) on rows
 from Sales
 where ([Time].[1997])
 </query>
    Attributes are name, resultCache.

      • setName

        public void setName​(String newName)
        Sets string attribute name, which identifies this query within its page. The <transform query> attribute uses this.

      • getName

        public String getName()

      • setResultCache

        public void setResultCache​(boolean newResultCache)
        Sets boolean attribute resultCache; if true, the query is parsed, executed, and converted to an XML document at most once. This improves performance and consistency, but the results may become out of date. We also need a way to prevent the cache using too much memory.

      • isResultCache

        public boolean isResultCache()
