java获取ResultSet长度Java，

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));
}
}
