Question

我正在尝试使用OCILIB接口将数据库与c ++程序连接。我的计划是： -

  #include "ocilib.h"
 int main(int argc, char *args[])
 {
OCI_Connection *cn;
if (!OCI_Initialize(NULL, NULL, OCI_ENV_DEFAULT))
    cout << "connection failed";
cn = OCI_ConnectionCreate("db", "usr", "pwd", OCI_SESSION_DEFAULT);
if (cn != NULL)
{

    cout <<OCI_GetVersionServer(cn);
    cout <<"Server major version : %i\n"<< OCI_GetServerMajorVersion(cn);
    cout <<"Server minor version : %i\n"<<OCI_GetServerMinorVersion(cn);
    cout <<"Server revision version : %i\n"<< OCI_GetServerRevisionVersion(cn);
    cout <<"Connection version : %i\n"<< OCI_GetVersionConnection(cn);

    OCI_ConnectionFree(cn);
}
OCI_Cleanup();

 }

此代码在MSVisualstudio2015中运行，我下载了所有OCI包并根据我的环境进行设置.. 我将链接器路径和其他包含头文件放在项目属性中。但是当我构建它所显示的应用程序时。

我读了一些关于这个问题的文件，但我无法解决这个问题，给我任何解决方案..

您需要将ociliba.dll从ocilib存档（在lib32 | 64文件夹下）复制到生成可执行文件的文件夹中。
