int insert_record(char *lab_login_name, char *login_ip,

time_duration2 = time_duration;　　／／－－－－宿主变量赋值

sprintf( sqlstr, "insert into z_detail_%d values (:v1, :v2, to_date(:v3, 'DY Mon DD HH24:MI:SS YYYY'), to_date(:v4, '
DY Mon DD HH24:MI:SS YYYY'), :v5, :v6)", day);
EXEC SQL PREPARE S FROM :sqlstr;
EXEC SQL EXECUTE S USING :lab_login_name2, :login_ip2, :login_date2,
:logout_date2, :lab_ip2, :time_duration2;
printf("timedurantion---------)>;%d",time_duration);
／／打印结果正常
printf("------------)>;%d",time_duration2);／／打印结果总是540702262

？？？？为什么不能正确赋值给time_duration2呢？请指教：）
