Question

Good Day,

I have an issue I could use your help with.

A customer would like invoice amounts displayed as follows:

Example Invoice Amounts

-405.12 to be shown as 000000040512

&

-400.00 to be shown as 000000040000

The following query works fine for the 405.12 amount, but for the 400.00 amount it drops the two zeros on the right side

LPAD(REPLACE((invoiceamt*-1),'.',''),12,0) 

How may I solve this issue?

Thank You Aaron

Answer 1

I suggest

 to_Char(abs(invoiceamt) * 100, '000000000000')

where

    abs  - absolute value - get rid of sign (-)
  * 100  - removing decimal point
to_Char  - final formatting (12 mandatory digits)

Answer 2

忘记替换，只需将发票乘以-100，然后将LPAD乘以所需的长度即可。

Answer 3

Another question has reminded me of the existence of the V format model element :

Returns a value multiplied by 10^ n (and if necessary, round it up), where n is the number of 9's after the V .

But you can use zeros instead of 9s to keep leading zeros, and add FM to remove the leading space (which is there for a - symbol for negative values - which you won't have). So you can also do:

with t (n) as (
  select -405.12 from dual
  union all select -400 from dual
)
select n, to_char(abs(n), 'FM0000000000V00') as result
from t;

         N RESULT

   -405.12 000000040512 
      -400 000000040000
