查看PL/SQL编译时的错误信息(转)

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

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

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             INVALID

3、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

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

SQL> desc dba_errors;
