Oracle 11g中的errorlogging参数增强了错误信息的记录功能，可以做到错误信息“落地”的功能。
1.Oracle版本信息
sys@11gR2> select * from v$version;
BANNER
----------------------------------------------------------------
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
PL/SQL Release 11.2.0.1.0 - Production
CORE 11.2.0.1.0 Production
TNS for Linux: Version 11.2.0.1.0 - Production
NLSRTL Version 11.2.0.1.0 - Production
2.SQL*Plus中errorlogging参数的默认值
sec@11gR2> show errorlogging
errorlogging is OFF
3.修改errorlogging选项为ON开启错误日志记录功能
sec@11gR2> set errorlogging on
sec@11gR2> show errorlogging
errorlogging is ON TABLE SEC.SPERRORLOG
注意再次提示的内容，“set errorlogging on”命令将自动在当前用户下创建表SPERRORLOG，用于记录错误信息。
sec@11gR2> desc SPERRORLOG
Name Null? Type
------------- -------- -------------------
USERNAME VARCHAR2(256)
TIMESTAMP TIMESTAMP(6)
SCRIPT VARCHAR2(1024)
IDENTIFIER VARCHAR2(256)
MESSAGE CLOB
STATEMENT CLOB
每个字段的定义描述如下：
USERNAME -- 用户名
TIMESTAMP -- 错误发生的时间
SCRIPT -- 脚本名称
IDENTIFIER-- 标识符
MESSAGE -- 记录类似ORA、PLA或SP2错误信息
STATEMENT -- 错误信息描述
4.模拟SQL*Plus中的错误
sec@11gR2> show secooler
SP2-0158: unknown SHOW option "secooler"
sec@11gR2> help secooler
SP2-0172: No HELP matching this topic was found.
sec@11gR2> seeeeelect from tab;
SP2-0734: unknown command beginning "seeeeelect..." - rest of line ignored.
sec@11gR2> create table t as as select * from user_objects;
create table t as as select * from user_objects
*
ERROR at line 1:
ORA-00928: missing SELECT keyword
sec@11gR2>
5.通过查询SPERRORLOG表获得所有错误信息
sec@11gR2> col USERNAME for a8
sec@11gR2> col TIMESTAMP for a14
sec@11gR2> col MESSAGE for a20
sec@11gR2> col STATEMENT for a20
sec@11gR2> select USERNAME,TIMESTAMP,MESSAGE,STATEMENT from SPERRORLOG;
USERNAME TIMESTAMP MESSAGE STATEMENT
-------- -------------- -------------------- --------------------
SEC 06-MAY-10 03.5 SP2-0158: unknown SH show secooler
1.49.000000 PM OW option "secooler"
SEC 06-MAY-10 03.5 SP2-0172: No HELP ma help secooler
1.51.000000 PM tching this topic wa
s found.
SEC 06-MAY-10 03.5 SP2-0734: unknown co seeeeelect from tab;
1.54.000000 PM mmand beginning "see
eeelect..." - rest o
f line ignored.
SEC 06-MAY-10 03.5 ORA-00928: missing S create table t as as
1.55.000000 PM ELECT keyword select * from user_
objects
可见，曾经发生的错误信息一览无余。
6.使用commit命令可以永久记录这些报错信息
若想将报错信息永久的保留下来，只需要在session中输入commit命令便可。
7.Oracle 11gR2官方文档中参考信息
http://download.oracle.com/docs/cd/B28359_01/server.111/b31189/ch12040.htm#SQPUG160
8.小结
通过参数errorlogging的设置，可以非常便捷的开启错误信息记录功能。当在SQL*Plus中调试脚本或SQL语句时，该功能起到非常重要的作用。
另外，通过这个错误记录功能，也可以建立一个误操作自检库，以便自省吾身。
Good luck.
