然后如果我希望variable dbid number; select dbid into :dbid from dba_hist_snapshot;可以作为主变量的值，例如：

:dbid

如何制作？

其实我只想执行@@？/ rdbms / admin / awrsqrpt.sql;没有交互式命令行。

Answer 1

这显示了如何运行报告。 sqlplus变量（非绑定变量）前面有一个＆符号，可以使用带有NEW_VALUE或OLD_VALUE选项的COLUMN语句进行设置。更多信息可以在Oracle SQL*Plus User's Guide and Reference

中找到

rem check ?/rdbms/admin/awrrpt.sql
rem and check ?/rdbms/admin/awrrpti.sql
rem we want not display a list of snap_ids
define num_days = 0;
rem we want to create a report of type text
define report_type='text';

rem choose the dbid of the current instance
column dbid old_value dbid;
select dbid from v$database;

rem choose the instance_number of the current instance for inst_num
column INSTANCE_NUMBER old_value inst_num
select INSTANCE_NUMBER from v$instance;


rem choose the last snap_id as END_SNAP
column end_snap new_value end_snap
select max(snap_id) end_snap
      from DBA_HIST_SNAPSHOT
  where DBID=&DBID
  and INSTANCE_NUMBER=&INST_NUM
/

rem choose the snap_id before the last snap_id as BEGIN_SNAP
column begin_snap new_value begin_snap
select max(snap_id) begin_snap
      from DBA_HIST_SNAPSHOT
  where DBID=&DBID
  and snap_id < &end_snap
  and INSTANCE_NUMBER=&INST_NUM
/

rem the following ways to define report_name do not work
rem because of leading blanks in the variables
rem define report_name=awr_&BEGIN_SNAP._&END_SNAP..txt
rem define report_name="awr_&BEGIN_SNAP._&END_SNAP..txt"

REM set the report name
column report_name old_value report_name
select 'awr_'||trim('&BEGIN_SNAP')||'_'||
  trim('&END_SNAP')||'.txt' report_name
from dual;

promp report_name &report_name
@?/rdbms/admin/awrrpt.sql

exit

-- get dbid, inst_num, bid, eid, sql_id for awr report
var dbid number;
var inst_num number;
var bid number;
var eid number;
var sql_id varchar2(20);
begin
    select dbid into :dbid from v$database;
    select instance_number into :inst_num from v$instance;
    select min(snap_id) into :bid from dba_hist_snapshot;
    select max(snap_id) into :eid from dba_hist_snapshot;
    :sql_id := 'xxxxx';
end;
