HS.FHIRServer.Storage.JsonAdvSQL.Search

Cache info about JSON Search columns needed to generate include queries

useful catch-all for SQL Queries, table aliases, which resource types have been 'included' via _include/_revinclude Structure: SearchContext("searchParameters") = ; reference to the HS.FHIRServer.API.Data.QueryParameters passed into the Search() method SearchContext("SELECT") = SearchContext("FROM") = SearchContext("JOINIDX") = counter for assigning Match query aliases SearchContext("JOINIDX", ) = SearchContext("sqlANDWHEREparams") = SearchContext("sqlANDWHEREparams", ) = SearchContext("sqlORWHEREparams") = SearchContext("sqlORWHEREparams", ) = SearchContext("whereClauseSeparator") =

Property methods: SearchContextDisplayToLogical(), SearchContextGet(), SearchContextIsValid(), SearchContextLogicalToDisplay(), SearchContextLogicalToOdbc(), SearchContextNormalize(), SearchContextSet()

Is 'handling=strict' from the Prefer http header

This property is set to 1 when ..strategy.GetStrategyConfigInfo()."use_top_for_maxresults" is true and is initialized when calling ##class(HS.FHIRServer.Storage.JsonAdvSQL.Interactions).%OnNew()

Allows specific interactions to compile a list of all resource types which are queried for this request (regardless of whether any are actually returned).

@API This method performs the requested search for resources and returns a HS.FHIRServer.Util.SearchResult with the selected resource information. If the query specifies _include or _revinclude parameters, then resources of type other than 'pResourceType' will be part of the result set. Included resources will be denoted in the result set 'Mode' column with the value 'include' @Input pResourceType The 'resourceType' of the resource to be searched @Input pCompartmentType If not "", indicates a compartment search of the specified Compartment Type and Id @Input pCompartmentId The ID of the resource comartment being searched @Input pParameters A HS.FHIRServer.API.Data.QueryParameters describing the query parameters specified for the search @Input pSortKeys (ByRef) A multi-dimensional structure describing any sorting to be performed on the result set. The structure of pSortKeys is an array of sort keys indexed 1-n: pSortKeys(n) = 1 for ascending, 0 for descending pSortKeys(n, "SearchParam") = An HS.FHIRServer.SearchParam object whose value is used to sort. @Return A HS.FHIRServer.Util.SearchResult object containing one row for each selected resource. @Throws The implementation must report errors via $$$ThrowStatus.

Perform all searching of included resources for _include and _revinclude search params. Recurses for :iterate modifier

This method is in the subclass of this (part of the Interactions object)

@API.Overridable
Return a Boolean value indicating whether SQL SELECT COUNT for _summary=count or _count=0 is allowed by this implementation.

The default implementation is to return True only if this is the base 'Json/JsonAdvSQL' strategy implementation. If the base implementation is overridden and customized, that implementation must OPT IN to allowing SELECT COUNT by overriding this method and adding their own desired heuristic.
@Input pResourceType The 'resourceType' of the resource to be searched
@Input pCompartmentType If not "", indicates a compartment search of the specified Compartment Type and Id
@Input pCompartmentId The ID of the resource comartment being searched
@Input pParameters A HS.FHIRServer.API.Data.QueryParameters describing the query parameters specified for the search
@Return Boolean value indicating whether using SQL SELECT COUNT is allowed.
