BUG# ODBCDBASE: 1858 (1.01.1928)

SYMPTOMS

The ODBC Access driver returns incorrect pcbValue when a column with the ODBC SQL type SQL_TIMESTAMP is converted to SQL_C_DATE via SQLBindCol or SQLGetData.

The following assumes that there is a table called DATETEST in which column number 2 is a column of type datetime:

  • SQLExecDirect the statement:

    select * from DATETEST
                            
  • Do a SQLBindCol on col #2 so that fCType is SQL_C_DATE.
  • Do a SQLFetch.
  • Examine the value of *pcbValue.

It will be 10; while the expected =6.

The same (invalid) pcbValue is returned if, instead of SQLBindCol, data is retrieved through SQLGetData with fCType = SQL_C_DATE.

Correct pcbValue is returned when fCType = SQL_C_TIME.

STATUS

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