Hi,
How can I trim the column size based on the data I entered in the column?
e.g.
name varchar2(100)
but I enter only 5 letter names
like
raj,ram etc
when I say select name from table;
it is displaying as
name
---------------------------------------------
raj
it is occupying 100 spaces and when I select another field it is displaying in the next line.
like select name,job from table;
name
-------------
job
-----------
raj
clerk
name
--------------
job
---------------
ram
accountant
in this way it is displaying
help me
thanx in advance

Hi there,
What you describe is normal SQL behaviour (select will always take column length and not the data in the column). I do not know of any way to format the output dependend on the data, but you can set the column size in sql. Try this:
col name format a20
Now execute your statement again.
If you want to select more than one column, you might want to consider a script. Something like:
col emp_id format 99 --> for numeric columns
col emp_name format a10 --> for alfanumeric columns
select emp_id
, emp_name
from employees
Hope this helps.
