default textsize in sybase - sybase

Question

the default textsize in sybase is 32768.
i can see this when i login to sybase and type:
1> select ##textsize
2> go
-----------
32768
(1 row affected)
when i did some googling i got the info that using the set command i can change the default textsize to my own value
1> set textsize 42768
2> go
1> select ##textsize
2> go
-----------
42768
(1 row affected)
But my problem here is this is not persisting.
as soon as i close the session,it sets back to 32768.
does anybody know how could i change the default textsize permanently in sybase.

Answer 1

There is no way to persist this it must be set within each session as required. There is no corresponding parameter for sp_configure.

If it's set within a stored procedure, the setting lasts for the stored procedure's scope.
select ##textsize
go
create procedure test_textsize as
set textsize 123456
select ##textsize
go
exec test_textsize
go
select ##textsize
go
Result
session_textsize
----------------
32768
(1 row affected)
proc_textsize
-------------
123456
(1 row affected)
(return status = 0)
session_textsize
----------------

This can be achieved using a login trigger in the login's default database.
create procedure login_trigger as
set textsize 12345
go
Add the login trigger to the user account.
sp_modifylogin a_login, "login script", login_trigger
go

Answer 2

From HERE!
The set textsize command specifies the limit, in bytes, of the text or image data to be returned with a select statement. For example, this command sets the limit on text or image data returned with a select statement to 100 bytes:
set textsize 100
The current setting is stored in the ##textsize global variable. The default setting is controlled by the client program. To reset the default, issue:
set textsize 0
I think the default value is configured when configuring the server.
