This is because you have cleared your result set.  The result sets are in
the output buffer.  Either you have get all the results by fetching them or
cancel the result before going for the next execution.

Yes, I am already using it that way.

My code is like :

dblib : create temp table
dblib : call stored proc ( which fills this temp table)
system : bcp the data out from the temp table
dblib : clear the temptable ( not necessary, but in future there will be
more actions added after this. )

and I wanted to do the bcp also using dblib, rather than using the back
ticks.
In the above sequence, I am getting a  "Sybase error: Attempt to initiate a
new SQL Server operation with results pending." when the bcp is called.
that is why !! ?? !! ??
