Well, if I understand it well, you call cs_loc_alloc usually before you connect to server, so there's no way, how could this function get info from server. It means, it has to be info about client, not the database server.

If you want to get default character set of server use this:

select sc.name
from syscharsets sc, sysconfigures c
where c.config=131
and c.value = sc.id

If you don't want to hardcode config = 131 use:

select sc.name
from syscharsets sc, sysconfigures c
where c.comment = "default character set id"
and c.value = sc.id

AFAIK database doesn't have it's own charset - default charset is just one for whole server.

AFAIK server doesn't know, what charset is client using - conversion is done on client's side. So, you can't get charset of client via SQL. Charset on client is usually defined in locales.dat file ( $SYBASE/locales/locales.dat )

Hi

I am using C technology to retrieve data stored in Sybase database using CT library functions

if I set the LC_CTYPE envoironment variable at the client end as per the database charset retrieved from the above query
will that still need conversion of data ???
basically i want to know
if i have to compare and check that whether database encoding and client encoding are set different
which envorinment variable should i choose

hi,

thanx for this knowledge
what i want to know is that when i call cs_loc_alloc it allocates structure CS_LOCALE and copies current localization information into CS_LOCALE structure i want to know that does it copy the client codepage info the structure or the database codepage into the structure
the query you have given me will give me the charset of database and if i have to check the client codepage
how should i go about it ??
