通过这里可以知道oerr其实就是通过awk对$ORACLE_HOME/rdbms/mesg/oraus.msg文件进行筛选，显示出来对应ORA-错误号的提示

One thought on “oerr ora code本质探讨”

  1. pl/sql实现错误号列表

    SET linesize 120
SET feedback off
SET SERVEROUTPUT ON
DECLARE
err_msg VARCHAR2(120);
BEGIN
dbms_output.enable (1000000);
FOR err_num IN 10000..10999
LOOP
err_msg := SQLERRM (-err_num);
IF err_msg NOT LIKE '%Message '||err_num||' not found%' THEN
dbms_output.put_line (err_msg);
END IF;
END LOOP;
END;
