我正在尝试执行以下插入:
INSERT INTO P_RESV_UNIT
(RESV_UNIT_ID, RATE_CODE,RESV_NUM,SEGMENT_CODE,PM_UNIT_TYPE_ID,HSKEEPING_SERVICE_CODE,ARRIVAL_DATE,DEPARTURE_DATE)
VALUES ('5000000000','OTC','507082784','DV','10676','WKL',TO_DATE('9/9/2013','dd/mon/yyyy'),TO_DATE('9/9/2013','dd/mon/yyyy'));
但我不断收到错误消息:不是有效月份。
如何正确输入?
