Question

I have to do some maintenance on a software that was delivered to a customer.
This software is using database and in order to do some debugging session on my computer, I had to install SQL server 2008 R2 and the two database (MyData and MyRecord) that are used by this software.
I had some troubles doing the setting (login, mapping of the database to sa user) but I managed to go over those issues.
Now I am trying to run the software but it crashes during initialization when it tries to open a recordset.

At first I do the following to connect to the database :

::CoInitialize(NULL);
try   
{   
    HRESULT hr = pConnection.CreateInstance("ADODB.Connection");   
    if (SUCCEEDED(hr))   
    {   
        pConnection->ConnectionTimeout = 0;   
        CString strConnect;
        strConnect.Format(_T("Data Source=MyRecord;uid=sa;pwd=sa123456;"));
        hr = pConnection->Open((_bstr_t)strConnect,"","", -1);
    }   
}

with pConnection defined as :

_ConnectionPtr pConnection;

After that, I am trying to read some data from the database “MyRecord” with the following code :

CString sqlQuery = _T("select * from 通道1设置参数表");
try
{
    pRecordset.CreateInstance(_uuidof(Recordset));
    pRecordset->Open(_bstr_t(sqlQuery ),pConnection.GetInterfacePtr(),adOpenDynamic,adLockOptimistic,adCmdText);
} 
catch(_com_error   *e)  
{  
    AfxMessageBox(e->Description());   
}  

with pRecordSet defined as :

_RecordsetPtr pRecordset;

When the line “pRecordset->Open(…)” is run, the software crashes in the function Recordset15::Open(…) of the msado15.tli file.
In this Recordset15::Open function, the raw_Open(…) function returns DB_E_NOTABLE.
However, I am sure that the table dbo.通道1设置参数表 exists in MyRecord database.

The error is :

I don’t know if the problem lies in the SQL server configuration or in the code.
This code works perfectly well on the customer’s PC so I would go with a configuration problem.
Thanks in advance !!

Answer 1

In the ODBC connector for this database, the setting “Change the default database to” was not set to the MyRecord database.
I have ticked the check-box, selected the database and now it is working correctly.
