jbpm 4中快速删除JBPM自带数据表数据的语句

delete from jbpm4_variable; delete from jbpm4_task; delete from jbpm4_property; delete from jbpm4_lob; delete from jbpm4_hist_actinst; delete from jbpm4_hist_procinst; delete from jbpm4_hist_task; delete from jbpm4_deployprop; delete from jbpm4_deployment; update jbpm4_execution set instance_=null; delete from jbpm4_execution;
