mysql分页sql
string sql = "select * from emp order by empno limit ?,?";
preparestatement stmt = con.preparestatement(sql);
stmt.setint(1, begin);
stmt.setint(2, end);
resultset rs = stmt.executequery();
while (rs.next()) {
system.out.println(rs.getint("empno") + ","
+ rs.getstring("ename") + ","
+ rs.getdouble("sal") + "," + rs.getdate("hiredate"));}
一直对rs.getxxx()的用法比较模糊，求介绍下用法 返回的结果集rs是不是既可以按列名rs.getxxx("xxx")也可以按rs.getxxx(1)这样读取啊？ 另外上面的代码中输出语句里面我可以不可以写成 while (rs.next()) { System.out.println(rs.getInt(1) + "," + rs.getString(2) + "," + rs.getDouble(3) + "," + rs.getDate(4));}
每个人都需要一台速度更快、更稳定的 PC。随着时间的推移，垃圾文件、旧注册表数据和不必要的后台进程会占用资源并降低性能。幸运的是，许多工具可以让 Windows 保持平稳运行。
