我试图勾画出“果园”的形式,给我带来以下结果。

to_char(0.1,  [FORMAT_SPEC] )

a. 提供0.1和:

to_char(1,  [FORMAT_SPEC] )

专 员 1. 导言

我尝试了以下解决办法:

to_char(0.1)

页: 1

to_char(0.1,  FM0.099 )

但是,这等于是:

to_char(1,  FM0.099 )

专 员 1. 导言0, which is not okay.

你们是否有任何建议?

问题回答

我只是利用这一点:

TRIM( .  FROM TO_CHAR(x,  FM99990.999 ))

冒着甲骨质的手来测试这一点,但我认为:

TO_CHAR(1,  FM0.999 )

应当这样做。

• 否则,0号拖车或mal子会以下列方式得到:

select val,
       case when val < 1 then to_char(val,  FM99990.9 )
            else to_char(val,  FM99999 )
       end fmt
  from (select 0.1 val from dual union all
        select 1 from dual
       )
/

       VAL FMT
---------- --------
        .1 0.1
         1 1
