二、进阶教程
参看官方文档实例，有详细的说明，包括：查询获取数据、绑定向量、数据库连接池、12c隐式结果集、使用Oracle对象和数据库通知等例子。这里只做一个最简单的插入数据演示。
1、简单的封装
void COciUtil::Init()
{
CString strAppPath = CMyFileUtil::GetAppPathW();//获得程序运行目录
ostring ociDllPath = CW2A(strAppPath);
try
{
Environment::Initialize(Environment::Default,ociDllPath);
}
catch (std::exception& e)
{
CString text(e.what());
AfxMessageBox(text);
}
}
void COciUtil::Clean()
{
try
{
conn.Close();
Environment::Cleanup();
}
catch (std::exception& e)
{
CString text(e.what());
AfxMessageBox(text);
}
}
BOOL COciUtil::Connect(CString ip,int port,CString serviceName,CString username,CString password)
{
try
{
CString strDB;
strDB.Format(L"%s:%d/%s",ip,port,serviceName);
char* db = CW2A(strDB);
char* user = CW2A(username);
char* pw = CW2A(password);
conn.Open(db,user,pw);
if (conn.IsNull())
return FALSE;
else
return TRUE;
}
catch (std::exception& e)
{
CString text(e.what());
AfxMessageBox(text);
return FALSE;
}
}
2、插入数据库
这里向数据库中插入数字、文本、时间、二进制。
BOOL COciDao::InsertTest()
{
try
{
COciUtil oci;
ocilib::Statement st(oci.conn);
st.Prepare("insert into TEST(ID,TEXT,TIME,BIN) values ( :id , :text , :date , :blob )");
int id = 123;
char* binaryText = "eee向天歌浮绿水";
ocilib::Blob blob(oci.conn);
vector list;
list.resize(strlen(binaryText));
for (int i=0;i
{
list.push_back(binaryText[i]);
}
blob.Write(list);
ostring ostr = "texttexttext";
COleDateTime time = COleDateTime::GetCurrentTime();
ocilib::Date date = COleDateTime2Date(time);
st.Bind(":id",id,BindInfo::InOut);
st.Bind(":text",ostr,50,BindInfo::InOut);
st.Bind(":date",date,BindInfo::InOut);
st.Bind(":blob",blob,BindInfo::InOut);
st.ExecutePrepared();
oci.conn.Commit();
oci.Clean();
}
catch (std::exception &e)
{
//cout<
CString text(e.what());
AfxMessageBox(text);
}
}
