如何获取在给定包中声明的所有类型的数据的信息
问题描述：
如何使用字典视图中的信息来获取Oracle 11g中给定包中声明的所有类型的数据的信息。
How can I use information from the dictionary views to get information on all types of data declared in a given package in Oracle 11g.
答
使用PL / Scope ...
Use PL/Scope ...
alter session set plscope_settings = 'IDENTIFIERS:ALL';
...并重新编译包（ UTL_LOG 在我的case）...
... and recompile the package (UTL_LOG in my case) ...
alter package utl_log compile;
alter package utl_log compile body;
...然后查询 user_identifiers view ...
... and then query the user_identifiers view ...
select name, type, object_name, object_type, line, col
from user_identifiers
where object_name = 'UTL_LOG'
and usage = 'DECLARATION'
and type not in ('VARIABLE','FUNCTION','FORMAL IN','FORMAL OUT','CONSTANT','PROCEDURE','FUNCTION','PACKAGE')
;
...（在我的例子中）yield ...
... which would (in my case) yield ...
NAME TYPE OBJECT_ OBJECT_ LINE COL
------------------- ------- ------- ------- ---- ---
ARR_SOME_COLLECTION VARRAY UTL_LOG PACKAGE 19 6
REC_SOME_RECORD RECORD UTL_LOG PACKAGE 15 6
TYP_LOG_CODE SUBTYPE UTL_LOG PACKAGE 8 9
请注意，PL / Scope可用于任何程序单元中声明/定义的任何标识符，而不仅仅是数据类型声明。
Please note that PL/Scope can be used for any identifier declared/defined in any program unit, not only for data type declarations.
