我的执行程序出现以下错误：
Error starting at line : 1 in command -
exec p_matrika(2010,2.5,'26311330')
Error report -
ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'P_MATRIKA'
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
06550. 00000 - "line %s, column %s:\n%s"
*Cause: Usually a PL/SQL compilation error.
*Action:
程序编译没有错误。我还检查了SQL语句，它可以正常工作，返回1行，所以我必须在程序本身做错了。我为SQL语句的一些混乱格式道歉。当我复制并粘贴它时，它以某种方式搞砸了。

您的调用中必须具有相同数量的参数，因为在过程指定中存在形式参数（除非存在任何默认的IN参数，这不是这里的情况）。每个OUT参数必须具有来自调用者的相应变量才能输入值。您的程序有12个正式参数。目前您正在为三个IN参数提供值，但您没有提供变量来接受九个OUT参数。
您可以使用在同一个匿名块中声明的本地PL / SQL变量作为您的调用，或者 - 可能更有用且接近您的C＃调用 - 绑定变量，这些变量在SQL * Plus或SQL Developer中（基于您对{的使用） {1}}）您可以使用exec命令进行定义：
variable例如，您可以在脚本的后续代码中使用绑定变量，并且可以通过您的调用在C＃中使用它们。
设置测试有点麻烦，尽管SQL Developer可以对其进行半自动化。它还假设总会有一个结果，你说的就是这种情况，但如果没有结果或多于一个，你将从程序中得到一个例外。
（顺便提一下，您的过程中不需要局部变量;您的查询可以直接选择variable out_unsec NUMBER;
variable out_supp NUMBER;
variable out_sec NUMBER;
variable limit_unsec NUMBER;
variable limit_supp NUMBER;
variable limit_sec NUMBER;
variable tenor_unsec NUMBER;
variable tenor_supp NUMBER;
variable tenor_sec NUMBER;
exec p_matrika(2010, 2.5, '26311330', :out_unsec, :out_supp, :out_sec, -
:limit_unsec, :limit_supp, :limit_sec, :tenor_unsec, :tenor_supp, :tenor_sec);
print out_unsec
print out_supp
...
，您不需要单独的中间unsec_out。您可能还需要思考关于命名约定，例如out_unsec用于形式参数，ans p_out_unsec用于局部变量，如果您决定保留它。使您更容易看到您正在使用和修改的内容，您当前的名字很容易混淆。）
另一种方法是使用引用游标：
l_out_unsec然后你可以这样做：
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;
或者你可以使它成为一个返回引用游标的函数。然后，您的C＃代码可以像处理任何其他结果集一样处理绑定的引用游标。
