SQL Plus 无法识别 Oracle PL/SQL 语句

Posted 2023-03-28

【中文标题】SQL Plus 无法识别 Oracle PL/SQL 语句

【英文标题】：Oracle PL/SQL statements not being recognised by SQL Plus

【发布时间】：2014-04-20 17:10:57

【问题描述】：

我在 64 位笔记本电脑上安装了 11g 32 位 Oracle Express。 sql plus 将任何 pl/sql 语句/语法视为错误，并且仅识别 sql 代码。

一定是某个地方的 Oracle 配置问题。这是在上一次安装遇到相同问题后全新安装的 Oracle Express。

其他人有这个问题吗？我已经在谷歌上搜索死了，但没有提出解决方案。

【问题讨论】：

发布声明和确切错误消息。

编辑了我的原始帖子以反映代码。

和任何 pl sql 代码（如 DECLARE、BEGIN）都会引发错误。虽然没有 sql 错误。

如何在 SQLplus 中运行这些语句？我猜你不会每次尝试时都输入它们。

'任何 PL/SQL 语句/语法' - 引发 ORA-00922 的最少代码是什么？除了 jonearles 指出的不正确的光标引用之外，您在循环中的选择没有选择 into 任何东西。

【参考方案1】：

替换

v_cid := ct;

与

v_cid := ct.ct;

代码必须引用cursor_name.column_name，即使游标和列名相同。此外，它总是有助于将问题减少到尽可能小的规模。

【讨论】：

谢谢你，但是在错误上没有区别。 SQL Plus 似乎对 PL SQL 产生了厌恶，并拒绝承认它的存在。自从移到新机器上，代码一切正常。

在 SQL*Plus 中即使是像这样的微不足道的 PL/SQL 块也会失败：exec null;

【参考方案2】：

免费的 Oracle Express 不支持 PlSql
