oracle 数据库时间类型为字符串 时间范围大小查询

select  * from  invoicedetail t2 where  t2.Memo is null   and  to_char(to_date(t2.PrintDate,'yyyy-MM-dd hh24:mi:ss'), 'yyyy-MM-dd')
 BETWEEN to_date('2016-09-01','yyyy-mm-dd') AND to_date('2016-09-29','yyyy-mm-dd' )

oracle 数据库存储过程 时间参数值 要以字符串类型传值 不能以日期传值 以防时间类型自动被截断为短日期格式

PROCEDURE   GET_ENDTIME
    (
 
      VRETURN_LIST OUT OUTPUTLIST,
     VUPLOADTIME IN VARCHAR2  --时间字段参数值要以字符串类型最佳
    )
