错误（13,10）：PLS-00428：此SELECT语句中需要INTO子句

错误（36,13）：PLS-00428：此SELECT语句中需要INTO子句

错误（59,16）：PLS-00428：此SELECT语句中需要INTO子句

Answer 1

您在所有INTO语句中都缺少SELECT子句。为此，您应首先声明将接受您选择的值的变量。在我的示例中，我声明了两个NUMBER数据类型变量（将接受ROW_NUMBER和COUNT函数的结果），而其他采用相应视图列的数据类型（这就是我使用column%type的原因语法）。

请注意，WHERE子句必须确保每个SELECT最多返回一行，否则您将获得TOO-MANY-ROWS（而如果它不返回任何内容，则为'我必须处理NO-DATA-FOUND）。

我为过程的参数添加了IN关键字。这是默认设置，但是 - 如果你真的使用它 - 毫无疑问你打算用它们做什么。

以下代码至少应该编译。虽然，整个代码都值得怀疑，因为你确实选择了一些值，但以后什么都不做。
