Method Detail

doCodeSystemsUpsert

public void doCodeSystemsUpsert(String paramList,
                                Collection<String> systemNames)

Description copied from class: ResourceReferenceDAO

Insert any missing values into the code_systems table

Specified by:

doCodeSystemsUpsert in class ResourceReferenceDAO

doCommonTokenValuesUpsert

protected void doCommonTokenValuesUpsert(String paramList,
                                         Collection<CommonTokenValue> tokenValues)

Description copied from class: ResourceReferenceDAO

Execute the insert (upsert) into the common_token_values table for the given collection of values. Note, this insert from negative outer join requires the database concurrency implementation to be correct. This does not work for Postgres, hence Postgres gets its own implementation of this method

Specified by:

doCommonTokenValuesUpsert in class ResourceReferenceDAO

insertResourceTokenRefs

protected void insertResourceTokenRefs(String resourceType,
                                       Collection<ResourceTokenValueRec> xrefs)

Description copied from class: ResourceReferenceDAO

Insert the values in the resource-type-specific _resource_token_refs table. This is a simple batch insert because all the FKs have already been resolved and updated in the ResourceTokenValueRec records

Overrides:

insertResourceTokenRefs in class ResourceReferenceDAO
