Class SearchQueryRenderer

java.lang.Object

com.ibm.fhir.persistence.jdbc.domain.SearchQueryRenderer

All Implemented Interfaces:

SearchQueryVisitor<QueryData>

public class SearchQueryRenderer
extends Object
implements SearchQueryVisitor<QueryData>

Used to render the domain model into a physical, executable query modeled as a Select statement. The domain model knows about resources and parameters. This class is used to translate the logical structure of the query into a physical one, using the correct table names, join predicates and filter expressions.

public QueryData includeRoot(String rootResourceType)

Description copied from interface: SearchQueryVisitor

The root query (select statement) for the include query. This query is different than the data root because of the need to support version references for _include searches.

However, we still need to assert that the resource has not been deleted, so we keep: xx_LOGICAL_RESOURCES.IS_DELETED = 'N'

getTokenParamTable

protected String getTokenParamTable(ExpNode filter,

                                    String paramAlias)

Compute the token parameter table name we want to use to join with. This method inspects the content of the given filter ExpNode. If the filter contains a reference to the TOKEN_VALUE column, the returned table name will be based on xx_TOKEN_VALUES_V, otherwise it will be based on xx_RESOURCE_TOKEN_REFS. The latter is preferable because it eliminates an unnecessary join, improves cardinality estimation and (usually) results in a better execution plan.

Parameters:

filter -

resourceType -

paramAlias -

Returns:
