编译无效对象是DBA与数据库开发人员常见的工作之一。对于编译过程中的错误该如何去捕获，下面给出两种捕获错误的方法。
一、当前数据库版本信息及无效对象
1、查看当前数据库版本
代码语言：javascript复制SQL> select * from v$version;
BANNER
----------------------------------------------------------------
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi
PL/SQL Release 10.2.0.4.0 - Production
CORE 10.2.0.4.0 Production
TNS for Solaris: Version 10.2.0.4.0 - Production
NLSRTL Version 10.2.0.4.0 - Production 2、获得数据库中的无效对象
代码语言：javascript复制set linesize 180
col object_name format a45
SELECT owner, object_name, object_type, status
FROM dba_objects
WHERE status = 'INVALID'
AND
object_type IN ('PROCEDURE', 'FUNCTION', 'TRIGGER', 'VIEW', 'PACKAGE');
OWNER OBJECT_NAME OBJECT_TYPE STATUS
------------------------------ --------------------------------------------- ------------------- -------
OTC_WRHS_POSITION OTC_WRHS_POSITION_PCK_tmp PACKAGE INVALID3、编译无效对象(编译方法很多，在此不一一列出)

--注意该包对象中包体的名字含小写字符，因此编译时使用双引号括起来
SQL> alter package "OTC_WRHS_POSITION"."OTC_WRHS_POSITION_PCK_tmp" compile body;二、捕获编译错误 1、使用show errors捕获错误
代码语言：javascript复制SQL> show errors;
No errors.
SQL> show errors package body "OTC_WRHS_POSITION"."OTC_WRHS_POSITION_PCK_tmp";
No errors. 2、如果使用show errors无法查询到错误，直接查询视图dba_errors
代码语言：javascript复制SQL> desc dba_errors;
