调用中的参数数量必须与过程规范中的形式参数数量相同，除非参数中有任何默认参数，但这里的情况并非如此。每个OUT参数都必须具有来自调用者的相应变量，才能将值放入。您的过程有12个形式参数。目前，您正在为三个IN参数提供值，但没有提供变量来接受九个OUT参数 您可以使用在与调用相同的匿名块中声明的本地PL/SQL变量，或者-可能更有用，更接近于您的C调用-绑定变量，在SQL*Plus或SQL Developer中，基于您对exec的使用，您可以使用variable命令定义： 例如，您可以在以后的脚本代码中使用bind变量，它们可以通过您在那里的调用在C中使用 虽然SQL开发人员可以半自动化地进行测试，但为测试设置起来有点混乱。它还假设始终只有一个结果，您已经说过是这样，但是如果没有结果或有多个结果，您将从过程中得到一个异常 顺便说一句，您的过程中不需要局部变量；您的查询可以选择直接进入unsec\u out，您不需要单独的中间输出unsec。如果决定保留命名约定，您可能还需要考虑命名约定，例如形式参数的p_out_unsec，局部变量的ans l_out_unsec。使您更容易看到正在使用和修改的内容，您当前的名称很容易混淆 另一种方法是使用ref游标：
create or replace PROCEDURE P_MATRIKA
(
leto IN NUMBER,
rating IN NUMBER,
davcna IN VARCHAR2,
p_refcur OUT SYS_REFCURSOR
)
AS
BEGIN
OPEN p_refcur FOR
... your query
END;
var refcur refcursor
exec p_matrika(2010, 2.5, '26311330', :refcur);
print refcur
或者您可以将其设置为返回ref游标的函数。然后，您的C代码可以像对待任何其他结果集一样对待绑定的ref游标。好的，我设法解决了我的问题。或者更好地说，亚历克斯·普尔解决了这个问题，所以他很荣幸：- Oracle存储过程：

您的过程有12个参数，您只通过了3个。“你认为输出值会去哪里？”阿列克斯普尔感谢你的迅速回复。我对PL/SQL非常陌生。我的目标是得到一个指定了9个OUT参数的行。您的过程有多个标量OUT参数，您根本不会得到“row”。您计划如何处理通话结果；您将如何使用这些值？您的过程中的查询实际返回多少行—始终是一行？我完全不知道为什么要在这里使用过程，而不是直接运行查询。它假设将值返回到我的C应用程序。是的，总是正好一排。我可以使用内嵌式SQL，但这样SQL每次运行时都必须编译，而存储过程只编译一次，这是不正确的。如果SQL不在缓存中，则对其进行硬解析，如果在缓存中，则进行更快的软解析。该过程的PL/SQL只编译一次，它调用的SQL与直接调用一样，仍然会得到软解析。但是，出于其他原因，比如可维护性等，您可能仍然希望在程序中使用它。Alex，谢谢您的详细回答。很明显，你很有知识，对我来说可能太有知识了：-。我反复阅读了你的答案好几次，试图使用你的解决方案，但都无法奏效。可能-由于我缺乏知识-我没有正确使用您建议的实现。在你的帮助下，我还是不能让它工作。我不明白在我的C代码中，带1个OUT参数的过程是如何像预期的那样工作的，但当我包含超过1个OUT参数时，它就不工作了。在C语言中，我只是在CommandText中使用SP，设置输入和输出参数，它就可以工作了。在SQL*Plus/SQL Developer中它对您有用吗？在C语言中，您需要设置所有9个输出参数（方向正确），并在命令文本中为它们设置正确数量的绑定占位符。如果它在SQL*Plus中使用wotk，但在C中仍然无法正确调用，那么最好提出一个新问题，说明过程规范和您在C代码方面的最佳尝试，以及您仍然遇到的错误。设置正确的标记不，我无法在SQL Developer中工作，也无法在C中工作。也许我的方法从一开始就是错误的。本质上，我需要的是一个过程或函数，将我的SQL语句结果返回给我的C应用程序，即：1行9个字段，如OUT参数中指定的。但是亚历克斯，尽管如此，我还是要感谢你为帮助我所做的一切努力。非常感谢。当心。@Flin-如果您想返回一行，请使用ref游标方法 . 作为过程put参数或函数返回值。。。
