在我的shell脚本中从pl / sql块出现此问题。这是脚本 PL / SQL BLOCK:
$ORACLE_HOME/bin/sqlplus -s system/${SysPwd}@${SList} <<!
--WHENEVER SQLERROR EXIT FAILURE;
SET SERVEROUTPUT ON SIZE UNLIMITED;
SET FEEDBACK OFF;
SET DEFINE OFF;
spool ${RESULT} append
DECLARE
TABLE_MISSING EXCEPTION;
PRAGMA EXCEPTION_INIT(TABLE_MISSING,-6550);
err_num NUMBER;
err_msg VARCHAR2(100);
cnt number;
sql_stmt varchar2(2000);
v_user varchar2(100) := '${User}';
p_username varchar2(100);
p_fullname varchar2(100);
p_account_state char(2);
BEGIN
select count(*) into cnt from users where upper(full_name) like '%${PaceUser}%';
if cnt <> 0 then
select rtrim(username),rtrim(full_name),account_state into p_username,p_fullname,p_account_state from users where upper(full_name) like '%${User}';
dbms_output.put_line('User ${User} exist in the database ${SList}.....');
end if;
EXCEPTION
when NO_DATA_FOUND then
NULL;
WHEN TABLE_MISSING
THEN
NULL;
WHEN OTHERS THEN
NULL;
END;
/
和错误:
ERROR:
select count(*) into cnt from users where upper(full_name) like '%TYLER MACHUTCHON%';

ERROR at line 16:

有任何想法或建议吗?
答案 0 :(得分:0)
WHEN TABLE_MISSING
THEN
NULL;
看起来您应该向调用者提出错误并使您的进程失败。 “缺少表格”不是您想要忽略的错误。
WHEN OTHERS THEN
NULL;
另一个非常糟糕的事情。除非你的过程没有任何意义,否则无人问津。

现在,对于实际修复,如果在运行时期间表可能存在或可能不存在,则需要使用动态sql来执行所有操作。要检查它是否存在,您可以使用数据字典视图(user_tables,all_tables或dba_tables)。
