loop but when i m executing this code it gives bus error(core dump) i
have debug this code but unable to solve... plz reply as soon as
possible....

Hello,

Can you provide a stacktrace for the core dump?

Also, what version of DB-Library are you using?
strings -a $SYBASE/$SYBASE_OCS/lib/libsybdb.so | grep Sybase

Finally, one note of caution. DB-Library is not threadsafe so
do not attempt to use it in a threaded application.
