因为Oracle将sql共享之后，截取出来的sql语句是带变量的
创建一个函数 jy_getsql来获得执行时的完整sql语句
CREATE OR REPLACE FUNCTION jy_getsql (my_sql_id in varchar2)
RETURN clob
IS
Result clob;
cursor jl(p_sql_id in varchar2) is
select decode(instr(b.BIND_NAME,'SYS'),0,':'||b.BIND_NAME||'',''||chr(58)||chr(34)||b.BIND_NAME||chr(34)||'') name,
decode(b.DATATYPE,2,dbms_sqltune.extract_bind(a.bind_data,b.POSITION).value_string ,''''||dbms_sqltune.extract_bind(a.bind_data,b.POSITION).value_string ||'''')
value_string
from v$sqlarea a ,v$sql_bind_metadata b
where a.LAST_ACTIVE_CHILD_ADDRESS = b.ADDRESS
and a.SQL_ID = p_sql_id
order by b.POSITION desc;
BEGIN
select a.SQL_FULLTEXT into Result
from v$sqlarea a where a.SQL_ID=my_sql_id;
for r in jl(my_sql_id) loop
Result := replace(Result,r.name,r.value_string);
end loop;
RETURN Result;
EXCEPTION
WHEN OTHERS
THEN
RETURN Result;
END;
下面的查询是查询数据库当前正处于等待状态的sql语句
select sw.sid,s.username,sw.event,sw.wait_time,sw.state,sw.seconds_in_wait,p.PROGRAM,s.MACHINE,
(select c.SQL_FULLTEXT from v$sqlarea c where c.SQL_ID=s.SQL_ID) sql_fulltext,
(select c.BIND_DATA from v$sqlarea c where c.SQL_ID=s.SQL_ID) BIND_DATA,s.SQL_ID,
jy_getsql(s.SQL_ID)
from v$session s,v$session_wait sw,v$process p
where s.username is not null and s.PADDR=p.ADDR
and sw.sid=s.sid and sw.event not like'%SQL*Net%'
order by sw.wait_time desc
但是这还有一缺点就是
select 1 userid from dual
这个1没有在v$sqlarea.bind_data中
但where子句中的绑定变量还是有了
