1打开数据库
BOOL playDlg::openData()
{
WCHAR a[100];
CString path;
path = m_exePath+L"sentence_making\\FROG.db";
memcpy(a,path,sizeof(a));
int nRet = sqlite3_open16((const char *)a,&pSQLite); // 链接到数据库，如果成功，数据库句柄指针存储于pSQLite 中
// 函数返回SQLITE_OK 表示连接成功，否则直接退出连接
if (nRet != SQLITE_OK)
{
AfxMessageBox(L"open DataBase failed");
}
return TRUE;
}
2、查询数据库
CString playDlg::selData(UINT num)
{
CString sentence;
sqlite3_stmt * stat;
CString sql2;
sql2.Format(L"select * from zao_ju_lian_xi where [index] = %d",num);
//sql2.Format(L"select * from zao_ju_lian_xi where [index] =");
sqlite3_prepare16(pSQLite,sql2,-1,&stat,0);
if(sqlite3_step(stat)==SQLITE_ROW )
sentence = (CString)sqlite3_column_text(stat,1);
sqlite3_finalize(stat);
sence[senNum] = sentence;
return sentence;
}
3、
关闭数据库
BOOL playDlg::closeData()
{
if (pSQLite)
{
sqlite3_close(pSQLite); // 关闭SQLite 数据库连接
pSQLite = NULL;
return TRUE;
}
else
{
return FALSE;
}
}
