在一个工程中，使用了jdbc加上oracle的jdbc驱动完成了访问oracle（8或者9）数据库的部分，由于需要保露c＋＋、c的接口所以业务逻辑采用从c++编写。
在经历了一番摸索后，还是有一个很苦恼的问题的困扰我，还是先把代码粘上来，
1.5 JDK
java：public int ChangeConnection(String IPString, String PortString, String DBName, String UserName, String Pwd)
{
try {
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
thin_con = DriverManager.getConnection(connectionString, UserName, Pwd);
///OUT
stmt = thin_con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_READ_ONLY);
rel_stmt = thin_con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_READ_ONLY);
list_stmt = thin_con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_READ_ONLY);
upDate_stmt = thin_con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE);
connectionString = recorder;
return 1;
} catch (Exception e) {
err = e.toString();
System.out.println(err);
return -1;
}
}c++:
获取jni，或者attach一个jni，然后调用以上的方法。出现的问题就是，在vc中完全编译后，启动会成功过去，但是去bin目录下面，启动生成的exe文件就会有可能出现访问冲突的错误，直接退出程序，而且有时候是直接在bin目录中启动exe就是正常的，启动几次后会出现同样的错误，但是只要在vc中启动，只要第一次是正确的，就永远是正确的，无论多少次，而且，当bin/exe启动失败后，vc的也将永远的启动失败，即使是debug模式也错误，只有重新的完全编译，而且完全编译后的bin/exe也不能保证会正确，或者永远正确，有个幸运的版本可以永远正确，可是当拷贝给同事的时候又出现同样的错误了。
后来验证是在java代码中的OUT前的那条语句出错的。之间都是好好的。

获取jni，或者attach一个jni，然后调用以上的方法。出现的问题就是，在vc中完全编译后，启动会成功过去，但是去bin目录下面，启动生成的exe文件就会有可能出现访问冲突的错误，直接退出程序，而且有时候是直接在bin目录中启动exe就是正常的，启动几次后会出现同样的错误，但是只要在vc中启动，只要第一次是正确的，就永远是正确的，无论多少次，而且，当bin/exe启动失败后，vc的也将永远的启动失败，即使是debug模式也错误，只有重新的完全编译，而且完全编译后的bin/exe也不能保证会正确，或者永远正确，有个幸运的版本可以永远正确，可是当拷贝给同事的时候又出现同样的错误了。
后来验证是在java代码中的OUT前的那条语句出错的。之间都是好好的。
