V$RESOURCE_LIMIT 的 Oracle DBMS_OUTPUT

Question

我正在尝试通过一个过程获取 V$RESOURCE_LIMIT 结果的 Oracle DBMS_OUTPUT。

但是，我收到关于 c1 不完整或格式错误的错误。

到目前为止，我有以下代码：

CREATE OR REPLACE PROCEDURE resource_output AS

CURSOR c1 IS SELECT resource_name , current_utilization , max_utilization , initial_allocation , limit_value FROM v$resource_limit;
TYPE rl_typ IS TABLE OF c1%ROWTYPE;
rl rl_typ;

BEGIN
 dbms_output.enable(100000);

   FOR rl IN (
    select * BULK COLLECT INTO rl from v$resource_limit
 )
  LOOP
    DBMS_OUTPUT.PUT_LINE('Resource Name = ' || rl.resource_name ||
                         ', Current Utilization = ' || rl.current_utilization ||
                         ', Max Utilization = ' || rl.max_utilization ||
                         ', Initial Allocation = ' || rl.initial_allocation ||
                         ', Limit Value = ' || rl.limit_value);
  END LOOP;

END resource_output;

Answer 1

对不起，我没有在 Oracle 实例面前​​更全面地帮助您。但是，我认为您对c1 的声明没有任何问题。

但是，您实际上并没有在您的过程中使用c1。你的FOR 循环应该是：

FOR rl IN (
  select * from v$resource_limit
) LOOP

...没有BULK COLLECT INTO r1。

CREATE OR REPLACE PROCEDURE resource_output AS


BEGIN
 dbms_output.enable(100000);

   FOR rl IN (
    select *  from v$resource_limit
 )
  LOOP
    DBMS_OUTPUT.PUT_LINE('Resource Name = ' || rl.resource_name ||
                         ', Current Utilization = ' || rl.current_utilization ||
                         ', Max Utilization = ' || rl.max_utilization ||
                         ', Initial Allocation = ' || rl.initial_allocation ||
                         ', Limit Value = ' || rl.limit_value);
  END LOOP;

END resource_output;

exec resource_output;

输出：

Answer 3

grant select any dictionary to that particular user;或者如果您只想授予 v$resource_limit 特权，则 grant select on v$resource_limit to particular user; 然后试试
