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)
/**************************************************/ /* Author: Robinson Cheng */ /* Blog: http://blog.csdn.net/robinson_0612 */ /* MSN: robinson_0612@hotmail.com */ /* QQ: 645746311 */ /**************************************************/ --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; Name Type Nullable Default Comments -------------- -------------- -------- ------- --------------------------------------------------------------- OWNER VARCHAR2(30) NAME VARCHAR2(30) Name of the object TYPE VARCHAR2(12) Y Type: "TYPE", "TYPE BODY", "VIEW", "PROCEDURE", "FUNCTION", "PACKAGE", "PACKAGE BODY", "TRIGGER", "JAVA SOURCE" or "JAVA CLASS" SEQUENCE NUMBER Sequence number used for ordering purposes LINE NUMBER Line number at which this error occurs POSITION NUMBER Position in the line at which this error occurs TEXT VARCHAR2(4000) Text of the error ATTRIBUTE VARCHAR2(9) Y MESSAGE_NUMBER NUMBER Y SQL> select owner,name,TEXT from dba_errors where owner='OTC_WRHS_POSITION' and name='OTC_WRHS_POSITION_PCK_tmp' and 2 sequence=(select max(sequence) from dba_errors where owner='OTC_WRHS_POSITION'); OWNER NAME TEXT -------------------- ------------------------- ------------------------------------------------------------ OTC_WRHS_POSITION OTC_WRHS_POSITION_PCK_tmp PLS-00103: Encountered the symbol "ULL" when expecting one o f the following: .
