How to add leading spaces in oracle?

Question

I want to add leading spaces in one of the column of the table. This ID column has data type Char(6).

Example: Table1

ID
1234
5678

when I do select * from Table1. and save file into .csv with pipeline delimited. It show spaces at the end of number.

Current output:

 |1234  |
 |5678  |

desired output

 |  1234|
 |  5678|

Answer 1

You'd need to trim the value to remove the trailing spaces and then lpad it to add the leading spaces

select lpad(trim(id),6)
  from your_table

Here is a sqlfiddle example that shows the steps

Answer 2

尝试：

select LPAD(trim(id), 2) from table
