我在Windows 7和Visual Studio 2012版本快遞工作。另一方面.csv文件到SQL Server,SQL服務器是 「SQL Server 2008 R2的」。上傳使用C++
我已經試過以下C++代碼:
#include <iostream>
#include <windows.h>
#include <string>
#include <sql.h>
#include <sqltypes.h>
#include <sqlext.h>
using namespace std;
void main()
{
clock_t start = clock();
SQLHANDLE sqlevent, sqlconnection, sqlstatement;
if(SQL_SUCCESS != SQLAllocHandle(SQL_HANDLE_ENV, SQL_NULL_HANDLE, &sqlevent))
{
cout<<"The sqlevent has failed to be created."<<endl;
system("pause");
return;
}
if(SQL_SUCCESS != SQLSetEnvAttr(sqlevent, SQL_ATTR_ODBC_VERSION, (SQLPOINTER)SQL_OV_ODBC3, 0))
{
cout<<"The sqlevent has failed to be initialized."<<endl;
system("pause");
return;
}
if(SQL_SUCCESS != SQLAllocHandle(SQL_HANDLE_DBC, sqlevent, &sqlconnection))
{
cout<<"The sqlconnection has failed to be created."<<endl;
system("pause");
return;
}
SQLCHAR retstring[10000];
SQLDriverConnect(sqlconnection, NULL, (SQLCHAR*)("DRIVER={SQL Server Native Client 10.0};SERVER=DATASERVER;DATABASE=DATABASE;UID=CrystalReports;PWD=PASSWORD"), SQL_NTS, retstring, 10000, NULL, SQL_DRIVER_NOPROMPT);
if(SQL_SUCCESS != SQLAllocHandle(SQL_HANDLE_STMT, sqlconnection, &sqlstatement))
{
cout<<"The sqlstatement has failed to be created."<<endl;
system("pause");
return;
}
string commandline;
commandline = "CREATE TABLE NEW_TABLE (ID VARCHAR(10), AGE FLOAT) GO ";
if(SQL_SUCCESS != SQLExecDirect(sqlstatement, (SQLCHAR*)(commandline.c_str()), SQL_NTS))
{
cout<<"The create table sql command has failed to excute."<<endl;
system("pause");
return;
}
commandline = "BULK INSERT NEW_TABLE FROM 'C:/temp/datafile.csv' WITH (FIELDTERMINATOR = ',', ROWTERMINATOR = '\n') GO";
if(SQL_SUCCESS != SQLExecDirect(sqlstatement, (SQLCHAR*)(commandline.c_str()), SQL_NTS))
{
cout<<"The import sql command has failed to excute."<<endl;
system("pause");
return;
}
clock_t end = clock();
cout<<"Import from .csv file to SQL Server costs "<<((end-start)/double(CLOCKS_PER_SEC))<<" seconds."<<endl;
system("pause");
return;
}
當我運行這段代碼,程序總是停在創建表。
我不知道如果我沒有創建表的權限,因此,我碼的手動創建的表。而且還有一個警告彈出:
我想知道,如果在上面的圖片所示的警告是我的代碼失敗的原因,還是我只是在代碼中所犯的錯誤?
非常感謝。
