Looks like do you want to change the width of the column. For that you need to use the Alter command like below.

ALTER TABLE yourtableName

Thanks Pawan for reply
Changes using above command is temporary or permanent.?
I mean changes in width value will be lost as soon as I logout from sybase?

Pawan,what will be the command for session specific setting as I don't want to change data default settings.
I need environment setting for so that output is displayed in good format.

you can use left or right function or both  and specify the number of characters returned in the query  ..
or  try  using the sp_autoformat stored procedure provided by sybase .

sp_autoformat will dynamically resize columns  wrt to the largets value   ..
performance may be a concern if processing large result sets ..

This is not session specific.  You can do changes for session in the SQL query. and that will not change the column size.
