ORA-20000：ORU-10027：buffer overflow,limit of 2000 bytes.

  ORA-20000：ORU-10027：buffer overflow,limit of 2000 bytes. 

 

这是由于在过程当中用到了dbms_output.put_line()在服务器端输出信息，而serveroutput   的size默认定义为10000bytes。 

修改一下size应该就能够了 

set serveroutput on 30000

 

ORA-20000 string 

Cause:The stored procedure RAISE_APPLICATION_ERROR was called which causes this error to be generated. 

Action:Correct the problem as described in the error message or contact the application administrator or database administrator for more information.

===============================================

写存储过程时遇到一个问题，执行dbms_output.putline(变量名)的时候，报错 ORA-20000：ORU-10027：buffer overflow,limit of 2000 bytes. $ oerr ora 20000 20000, 00000, "%s" // *Cause:  The stored procedure 'raise_application_error' //          was called which causes this error to be generated. // *Action: Correct the problem as described in the error message or contact //          the application administrator or DBA for more information. 应该是变量大小超过了dbms_output.putline的最大值。 解决办法： SQL>set   serveroutput   on   size   1000000    ##2014-07-18添加 解决办法2： 在begin后面加上DBMS_OUTPUT.ENABLE(buffer_size => null) ，表示输出buffer不受限制。 以下面的语句是为了获取建立索引语句 set serveroutput on declare   v_sql    varchar2(1000);   v_result varchar2(2000); begin   for cur_sql in (select 'select dbms_metadata.get_ddl(''INDEX'',''' ||                          T.INDEX_NAME || ''',''XXXX'') FROM DUAL' as f_sql                     from v$object_usage t                    where t.monitoring = 'YES'                      AND T.USED = 'NO') loop     begin       DBMS_OUTPUT.ENABLE(buffer_size => null); --表示输出buffer不受限制       execute immediate cur_sql.f_sql         into v_result;       --DBMS_OUTPUT.PUT_LINE(cur_sql.f_sql);       DBMS_OUTPUT.PUT_LINE(v_result);     end;   end loop; end; /
