oracle 获取某个包 依赖的所有对象包括其子对象 使用了一个一个临时表 记录了已经遍历的 节点 同时 使用了层数来记录已经遍历的 包 效率一般,可以改动性大 declare -- 获取相应的 某个程序包 所需要应用的包 cursor p_cur(p_name varchar2) is select dd.na

   oracle 获取某个包 依赖的所有对象包括其子对象

  使用了一个一个临时表 记录了已经遍历的 节点

  同时 使用了层数来记录已经遍历的 包

  效率一般,可以改动性大

  declare

  -- 获取相应的 某个程序包 所需要应用的包

  cursor p_cur(p_name varchar2) is

  select dd.name, dd.type, dd.referenced_name, dd.referenced_type

  from dba_dependencies dd

  where 1 = 1

  and dd.referenced_type in

  ('PACKAGE', 'SYNONYM', 'TABLE', 'SEQUENCE')

  and dd.type in ('PACKAGE', 'PACKAGE BODY')

  AND dd.name = p_name;

  cursor p_temp(l_level number) is

  select attribute1, attribute2

  from cux_common_imports_temp

  where attribute2 = l_level;

  p_root_name varchar2(30);

  p_level number := 0;

  p_count number := 0;

  begin

  --将根节点 放入到表中

  p_root_name := 'CUX_SBU_COMMON';

  insert into cux_common_imports_temp

  (attribute1, attribute2)

  values

  (p_root_name, p_level);

  p_count := 1;

  --循环这一层的 节点 并获得其子节点

  while p_count != 0 loop

  for p_loop in p_temp(p_level) loop

  --下一层

  p_level := p_level + 1;

  p_root_name := p_loop.attribute1;

  for p_rec in p_cur(p_root_name) loop

  if p_rec.referenced_type = 'PACKAGE' then

  --如果表内 没有这个程序就 加入到 临时表中

  select count(*)

  into p_count

  from cux_common_imports_temp

  where attribute1 = p_rec.referenced_name;

  if p_count = 0 then

  insert into cux_common_imports_temp

  (attribute1, attribute2)

  values

  (p_rec.referenced_name, p_level);

  end if;

  --输出相应的 子节点信息

  dbms_output.put_line(p_level || '-Name:' ||

  p_rec.referenced_name || '-Type:' ||

  p_rec.referenced_type);

  end if;

  end loop;

  end loop;

  --获取 该层是否为空

  select count(*)

  into p_count

  from cux_common_imports_temp

  where attribute2 = p_level;

  end loop;

  end;
