方法一：：
方法二：：
SELECT sql_text
FROM v$sqltext a
WHERE (a.hash_value, a.address) IN
(SELECT DECODE(sql_hash_value, 0, prev_hash_value, sql_hash_value),
DECODE(sql_hash_value, 0, prev_sql_addr, sql_address)
FROM v$session b
WHERE b.paddr = (SELECT addr FROM v$process c WHERE c.spid = '232279'))
ORDER BY piece ASC
或者也可以通过一下查询
select t3.SQL_TEXT
from v$process t1
inner join v$session t2
on t1.ADDR = t2.PADDR
inner join v$sql t3
on t2.SQL_ID = t3.SQL_ID
where t1.SPID = 172928（这个pid就是进程id）;
列出使用频率最高的5个查询：
select sql_text,executions
from (select sql_text,executions,
rank() over
(order by executions desc) exec_rank
from v$sql)
where exec_rank <=5;
消耗磁盘读取最多的sql top5：
select disk_reads,sql_text
from (select sql_text,disk_reads,
dense_rank() over
(order by disk_reads desc) disk_reads_rank
from v$sql)
where disk_reads_rank <=5;
找出需要大量缓冲读取（逻辑读）操作的查询：
select buffer_gets,sql_text
from (select sql_text,buffer_gets,
dense_rank() over
(order by buffer_gets desc) buffer_gets_rank
from v$sql)
where buffer_gets_rank<=5;
