How can I insert record in Microsoft Access?

CString SqlString;
CString name="I want to add this variable in Table3";
SqlString = "INSERT INTO Table3 (Name,Numbers) VALUES (name,099)";

When I do it that way gives the following error:

Database error:Too few parameters.Expected 1.

This is a snippet from my own application:

BOOL CCommunityTalksApp::SetRecordForTalkNumber(int iTalkNumber, UINT uID, CString &rStrError)
{
    CDatabase   *pDatabase;
    CString     strSQL, strField;
    BOOL        bOK;

    pDatabase = theApp.GetDatabase();
    if(pDatabase != nullptr)
    {
        if (iTalkNumber == 9999)
            strField = _T(" ");
        else
            strField.LoadString(uID);
        strSQL.Format(_T("INSERT INTO [Public Talk Titles] ([Theme], [Category], [Talk Number]) VALUES ('%s', 'NS', %d)"), strField, iTalkNumber);

        TRY
        {
            pDatabase->ExecuteSQL((LPCTSTR)strSQL);
            bOK = TRUE;
        }
        CATCH(CDBException, Except)
        {
            rStrError = Except->m_strError;
            bOK = FALSE;
        }
        END_CATCH
    }

    return bOK;
}

As you can see:

  1. Use [ and ] to wrap the table and field names to address any issues with spaces.
  2. Qualify the field names first — particularly if you are only populating certain field values.
  3. Wrap the string values with single quotes.

So:

SqlString = "INSERT INTO Table3 (Name,Numbers) VALUES (name,099)";

Would be something like:

SqlString = "INSERT INTO [Table3] ([Name],[Numbers]) VALUES ('name',099)";

I appreciate that the square brackets are not needed for your table / field names though.
