David,
"perldoc DBD::Sybase" says:
You can get the type of the current result set with
$sth->{syb_result_type}. This returns a numerical value,
as defined in $SYBASE/include/cspublic.h:
#define CS_ROW_RESULT (CS_INT)4040
#define CS_CURSOR_RESULT (CS_INT)4041
#define CS_PARAM_RESULT (CS_INT)4042
#define CS_STATUS_RESULT (CS_INT)4043
#define CS_MSG_RESULT (CS_INT)4044
#define CS_COMPUTE_RESULT (CS_INT)4045
In particular, the return status of a stored procedure is
returned as CS_STATUS_RESULT (4043), and is normally the
last result set that is returned in a stored proc execu-
tion.
The script in your original posting doesn't use syb_result_type. It might
be just what the doctor ordered. Dr. Bill, that is.
