Plsql PL/SQL联合语句公共变量需要定义？

任何人都可以帮我如何定义工号，而不是通常键入每一行。我需要在代码的开头定义这个变量，脚本需要从那里调用它

---

我希望得到任何一个查询的结果？

请使用{}符号格式化查询。它不可读。您是否尝试从外部使用jobno=123？您需要在此处与表达式一起使用。外部我有define by Declare方法，但它无法工作。实际上我不认识神谕。我是一名在公司实施的学习者。因此，请更正我的代码并输入完整的代码。我想在这个脚本之外声明的Jobno在每个表中都应该被选中。请更正并放入完整的脚本。thanks@senthilkumar通过在代码中引入变量，您到底想要实现什么？它的目的是什么？我不想在每一行中键入Jobno，而是希望在脚本顶部定义，从那里程序应该调用automatic。谢谢你的回复。我期待你的答案如何做到这一点？不是很好的代码示例。至少您必须在INTO子句中说明如何使用变量。@Dmitry的问题是如何在PL/SQL中定义变量来引用它。我在答复中确实提到了这一关切。您是否建议为每个问题编写综合教程？
