public NativeSQLQueryPlan getNativeSQLQueryPlan (NativeSQLQuerySpecification spec)

public ParameterMetadata getSQLParameterMetadata (String query)

Obtain the parameter metadata for given native-sql query.

for native-sql queries, the param metadata is determined outside any relation to a query plan, because query plan creation and/or retrieval for a native-sql query depends on all of the return types having been set, which might not be the case up-front when param metadata would be most useful

Parameters
query The query
Returns
  • The parameter metadata
