java获取ResultSet长度

 

public class Test { public static void main(String[] args) throws SQLException {  Connection conn = WLMGlobal.connMgr_stat_instance().getConnection();  Statement stmt = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);  ResultSet rs = stmt.executeQuery("select distinct logid from stat_data");    rs.last(); //结果集指针知道最后一行数据  int n = rs.getRow();  System.out.println(n);    rs.beforeFirst();//将结果集指针指回到开始位置，这样才能通过while获取rs中的数据  while(rs.next()){   System.out.println(rs.getInt(1));  } }}
