  • %META:TOPICPARENT{name="VirtTipsAndTricksGuide"}% ---++How to rename a RDF Graph in the Virtuoso Quad Store ---+++Rename RDF Graph A RDF Graph in the Virtuoso Quad Store can be renamed without copying each assertion from the old graph to the new graph using a SQL statement, this being what the Conductor "rename" option does, which is: <verbatim> UPDATE DB.DBA.RDF_QUAD TABLE OPTION (index RDF_QUAD_GS) SET g = iri_to_id ('new') WHERE g = iri_to_id ('old', 0); </verbatim> <b>Note</b>: this operation must be run in <i>row-autocommit</i> mode i.e. <code>log_enable (3)</code>, and then restore back to the default logging mode of 1. ---+++Rename RDF Graph Group For Virtuoso Graph Groups two tables need to be updated: <verbatim> UPDATE DB.DBA.RDF_GRAPH_GROUP_MEMBER SET RGGM_GROUP_IID = iri_to_id ('new') WHERE RGGM_GROUP_IID = iri_to_id (old) </verbatim> and <verbatim> UPDATE DB.DBA.RDF_GRAPH_GROUP SET RGG_IID = iri_to_id ('new') , RGG_IRI = 'new' WHERE RGG_IRI = 'old' </verbatim> ---+++Related * [[VirtTipsAndTricksGuide][Virtuoso Tips and Tricks Collection]] * [[http://docs.openlinksw.com/virtuoso/rdfperformancetuning.html][RDF Performance Tuning]]
