平台：运行Oracle 10g的Windows
我必须修改一些旧的dll库代码并使用Oracle进行预编译 Pro * C / C ++ 9.0.1.1.1，现在我发现了代码 for（;;）无论什么时候没有找到，休息不再有效，它只是保持 循环。 我在这里准备了一些代码，显示在预编译之前和之后 还有一个日志。 在此先感谢能够提供帮助的人。

答案 0 :(得分：0)
我知道零Pro * C，但我相信最普遍接受的语法是这个
EXEC SQL WHENEVER NOT FOUND DO break;
for(;;)
//statement
EXEC SQL WHENEVER NOT FOUND CONTINUE;
此外，在检查 not found 值时，我通常会检查sqlcode 100，而不是1403.我不确定区别是什么，但我已经看到了。
答案 1 :(得分：0)
在原始的fmt_clnt.pc文件中，您有以下代码：
/* exec sql INCLUDE sqlca; */
此代码应删除并替换为：
#include <sqlca.h>
文件中的代码是围绕以前的版本构建的，可能会对结构进行细微的更改。当您从一个主要版本转到另一个主要版本或Oracle时，尤其如此。
答案 2 :(得分：0)
对于那些仍然感兴趣的人： 我终于通过构建一个干净的PC然后安装旧版本的预编译器来解决这个问题。 比较2个输出似乎sqlca.sqlcode的数据类型导致了问题。 Pro c ver 2.2 sqlcode很长，而pro c ver 9.0是整数。这可以解释为什么我总是得到归零。 感谢所有贡献者。
