BUG# odbcdbase: 2126 (1.01.1928)

SYMPTOMS

When an ODBC application, using any of the desktop drivers (dBASE, FoxPro, Paradox, BTRIEVE, Access, Excel, and Text), executes a USE statement, a memory loss of 2048 bytes occurs. For example, the following sequence of calls exhibit the behavior:

   SQLAllocEnv(&henv);
   SQLAllocConnect (henv, &hdbc);
   SQLDriverConnect (hdbc, hwnd, "", 0, szConnStrOut, cbConnStrOutMax,
                     &cbConnStrOut, SQL_DRIVER_PROMPT);
   SQLAllocStmt(hdbc, &hstmt);
   SQLExecDirect(hstmt,"use c:\\",SQL_NTS);
   SQLFreeStmt (hstmt, SQL_DROP);
   SQLDisconnect(hdbc);
   SQLFreeConnect(hdbc);
   SQLFreeEnv(henv);
                

STATUS

Microsoft has confirmed this to be a problem in ODBC Desktop Drivers version 1.01.1928. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
