SQL query returns DB_E_NOTABLE - c++

Question

I'm building my first MFC app. I'm successfully connecting to the database, but when I try to execute a query, hResult becomes DB_E_NOTABLE.
This is my code:
class CCitiesTable : public CTable<CAccessor<CCitiesTableAccessor> >
{
public:
bool SelectAll(CCitiesArray& oCitiesArray)
{
CDataSource oDataSource;
CSession oSession;
CCitiesTable oCitiesTable;
try
{
HRESULT hResult = CoInitialize(0);
if (FAILED(hResult))
{
//Message( _T("Unable to CoInitialize COM Interface.") );
return FALSE;
}
CDBPropSet oDBPropSet(DBPROPSET_DBINIT);
oDBPropSet.AddProperty(DBPROP_INIT_DATASOURCE, _T("LENOVO2\\SQL2008") ); // сървър
oDBPropSet.AddProperty(DBPROP_AUTH_USERID, _T("sa") );
oDBPropSet.AddProperty(DBPROP_AUTH_PASSWORD, _T("massive") );
oDBPropSet.AddProperty(DBPROP_INIT_CATALOG, _T("PhoneBookDB" ));
oDBPropSet.AddProperty(DBPROP_AUTH_PERSIST_SENSITIVE_AUTHINFO, false);
oDBPropSet.AddProperty(DBPROP_INIT_LCID, 1033L);
oDBPropSet.AddProperty(DBPROP_INIT_PROMPT, static_cast<short>(4));
// Свързваме се към базата данни
hResult = oDataSource.Open(_T("SQLOLEDB.1"), &oDBPropSet);
if (FAILED(hResult))
{
//Message(_T("Unable to connect to SQL Server database. Error: %d"), hResult);
return FALSE;
}
//Open session
hResult = oSession.Open(oDataSource);
if (FAILED(hResult))
{
//Message(_T("Unable to open session. Error: %d"), hResult);
oDataSource.Close();
return FALSE;
}
//Make query
CString strQuery;
strQuery = _T("SELECT * FROM dbo.CITIES");
// Execute query
hResult = oCitiesTable.Open(oSession, strQuery);
After executing the code above hResult is DB_E_NOTABLE. Except that the table is there. Database: PhoneBookDB Schema: dbo Table: CITIES. The query works just fine in SQL Server Management Studio.

According to the documentation for CTable::Open, CTable::Open expects a table name, not a select query. The error you are getting is saying that "SELECT * FROM dbo.CITIES" is not a table name (which it is not).
szTableName
[in] The name of the table to open, passed as an ANSI string.
You need to use:
CString strTable = _T("CITIES");
// Open Table
hResult = oCitiesTable.Open(oSession, strTable);
