eliminate extra spaces in VARCHAR columns In a table, I have an ID column defined as BIGINT(8) and one VOUCHER column that is VARCHAR(100). No matter the actual length of the value in that field, the SQL always returns a full length value, which can be cumbersome in CLI, specially when selecting more fields. 

Here is a sample of what I'm getting

ID                   VOUCHER                                                                                               
-------------------- ----------------------------------------------------------------------------------------------------                                                                   
               26462 7083d8374831148f9e2271741529ee37                                                                                                                                                 
               26624 9170220e6971c2414613d0a69b420156

I tried TRIM / LTRIM / RTRIM functions, but without success.

What can I use to get something along these lines, at least for display purposes:

ID     VOUCHER                           
------ --------------------------------
26462  7083d8374831148f9e2271741529ee37
26464  9170220e6971c2414613d0a69b420156
26465  b75d12847a24981d36f7bfcd58e8a230
Thanks to @JNK's comment, select cast(trim(id) as varchar(6)) as id, cast(trim(voucher) as varchar(32)) as voucher, auth from my_table does the job.
