每当我使用Sql * plus运行sql脚本并检查$？,即使脚本不成功,也会得到0.

例

#$sqlplus user/password@instance @script.sql

我希望在发生错误时返回非零值.

我该如何实现呢？

你必须明确地告诉sqlplus在你的脚本中这样做.基本上可以使用两个语句：

> WHENEVER SQLERROR EXIT SQL.SQLCODE
> WHENEVER OSERROR EXIT

例如：

WHENEVER SQLERROR EXIT SQL.SQLCODE
begin
  SELECT COLUMN_DOES_NOT_EXIST FROM DUAL;
END;
/

并且对于操作系统错误：

WHENEVER OSERROR EXIT FAILURE
START no_such_file

希望它有帮助.祝你好运！
