VC调用存储过程的通用方法（SQLServer篇）
这里讨论的是ADO调用存储过程，按MSDN的例子，一般都是下面的调用方法（节选自MSDN）：
HRESULT hr = S_OK;
// Define ADO object pointers.
// Initialize pointers on define.
// These are in the ADODB:: namespace.
_RecordsetPtr pRstByRoyalty = NULL;
_RecordsetPtr pRstAuthors = NULL;
_CommandPtr pcmdByRoyalty = NULL;
_ParameterPtr pprmByRoyalty = NULL;
_ConnectionPtr pConnection = NULL;
_bstr_t strCnn("Provider=sqloledb;Data Source=srv;"
"Initial Catalog=Pubs;User Id=sa;Password=;");
_bstr_t strMessage, strAuthorID;
int intRoyalty;
VARIANT vtRoyalty;
try
{
//Open a Connection.
TESTHR(pConnection.CreateInstance(__uuidof(Connection)));
hr = pConnection->Open(strCnn,"","",NULL);
pConnection->CursorLocation = adUseClient;
//Open Command Object with one Parameter
TESTHR(pcmdByRoyalty.CreateInstance(__uuidof(Command)));
pcmdByRoyalty->CommandText = "byroyalty";
pcmdByRoyalty->CommandType = adCmdStoredProc;
//Define Integer/variant.
vtRoyalty.vt = VT_I2;
vtRoyalty.iVal = intRoyalty;
pprmByRoyalty = pcmdByRoyalty->CreateParameter(
"percentag

2.如果先添加参数再prepare，就必须设置参数的类型，大小，精度才能通过，比如char,varchar,decimal类型，而int,float有固定字节类型的数据类型则可不用设置大小。
