 ORA-20000:ORU-10027:buffer overflow,limit of 2000 bytes.  这是因为在过程中用到了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应该就可以了 set serveroutput on 30000 ORA-20000 string Cause:The stored procedure RAISE_APPLICATION_ERROR w…

    要用dbms_output.put_line来输出语句,遇到以下错误: ERROR 位于第 1 行: ORA-20000: ORU-10027: buffer overflow, limit of 10000 bytes ORA-06512: 在"SYS.DBMS_OUTPUT", line 32 ORA-06512: 在"SYS.DBMS_OUTPUT", line 97 ORA-06512: 在"SYS.DBMS_OUTPUT", l…

下午的时候在 PL/SQl Developer 10.0.5.1710 上调试壹個存储过程,在调试的时候使用了比较多的 DBMS_OUTPUT.PUT_LINE 作为打印日志的方式,结果没过多久 PLSQL 客户端就开始提示如下错误:ORA-20000: ORU-10027: buffer overflow, limit of 10000 bytes,分析下来是因为函数DBMS_OUTPUT.PUT_LINE()是在循环体中打印结果的,因此,循环执行多少次,这個函数就会执行多少次, 导致缓冲区很…
