Oracle中，表名和列名要加雙引號割去，字符值要加單引號蜡峰，以下是R語言中相關(guān)語句：
sql = paste0('insert into "modelprediction" ("t_model", "t_road_id", "t_date", "t_risk") values ', "('NextDayMacro', '1', to_date('",substr(Sys.time() ,0,10),"','YYYY-MM-DD'),'",pred$pred,"')")
dbSendUpdate(conn, sql)
dbGetQuery(conn, 'select * from "modelprediction"')
