在PL/SQL匿名块之后，需要有一个/字符来允许DDL语句运行

在PL/SQL匿名块之后，需要有一个/字符才能允许DDL语句运行

您似乎正在尝试执行PL/SQL匿名块，但很快就关闭了该块。也就是说，第一个端点，你可能只是想关闭try-catch块，实际上关闭了整个东西。可能您被DECLARE搞糊涂了，它启动匿名块，但不是启动代码块——您仍然需要开始它。试着这样做：

尝试指定插入中的列。e、 g插入Lab1_选项卡值，lastName值Lab1_SEQ.NEXTVAL，v_lname；刚刚尝试过，同样的错误也发生了尝试将INSERT放在BEGIN/ENDdustyrush中是正确的，而且问题是因为在第4行BEGIN之后缺少额外的BEGIN。请尝试指定INSERT中的列。e、 g插入Lab1_选项卡值，lastName值Lab1_SEQ.NEXTVAL，v_lname；刚刚尝试过，同样的错误也发生了尝试将您的插入放入BEGIN/ENDdustyrush是正确的，而且问题是由于在第4行BEGIN之后缺少额外的BEGIN。这不完全正确。这只是一个客户端应用程序块分隔符。它传统上用于Oracle DB客户端，因为Oracle的SQLPlus使用它作为默认PL/SQL分隔符。这是一种告诉SQLPlus您已经完成PL/SQL的方法，因此它将代码发送到Oracle DB，而不使用斜杠字符。您在技术上是正确的。最好的一种是正确的。谢谢你的澄清！不完全正确。这只是一个客户端应用程序块分隔符。它传统上用于Oracle DB客户端，因为Oracle的SQLPlus使用它作为默认PL/SQL分隔符。这是一种告诉SQLPlus您已经完成PL/SQL的方法，因此它将代码发送到Oracle DB，而不使用斜杠字符。您在技术上是正确的。最好的一种是正确的。谢谢你的澄清！添加一个解释可能会很好地插入到Lab1_选项卡值Lab1_SEQ.NEXTVAL，v_lname；如果Lab1_tab中有两列分别与值列表中的参数完全兼容的数据类型，则insert语句可以正常工作。添加解释可能有助于将insert插入Lab1_tab值LABB1_SEQ.NEXTVAL，v_lname；如果Lab1_tab有两列分别与值列表中的参数完全兼容的数据类型，则insert语句可以正常工作。
