当iv_from_date的输入以此格式04/01 / 2013给出时，我收到错误，当输入采用此格式时，它会完美地运行04 / Jan / 2013.nls日期格式为DD-MON_RR.My输入应该采用这种格式04/01 / 2013.How我这样做

请避免使用VARCHAR2类型的变量和参数，实际上类型为DATE。 Oracle尝试隐式地将varchar参数转换为date。当格式与NLS_DATE_FORMAT中设置的格式相同时，它会失败。同时将iv_from_date和iv_to_date输入为DATE。如果表TAX_P中的相应列被输入为varchar2，则在insert语句中进行显式格式转换。
