I posted the following to the pyodbc google group, but got no reply - it
seems a bit quiet there. I hope someone here can help.
I am using pyodbc version 2.1.6 on Windows Server 2003, connecting to Sql
This works -
>>> cur.execute('select ?', None)
<pyodbc.Cursor object at 0x00A91368>
This does not work -
>>> cur.execute('select * from ctrl.dirusers where todate is ?', None)
Traceback (most recent call last):
File "<stdin>", line 1, in <module> pyodbc.ProgrammingError: ('42000',
" [Microsoft][ODBC SQL Server Driver][SQL Server]Incorrect syntax
near @P1'. (102) (SQLExecDirectW);  [Microsoft][ODBC SQL Server
Driver][SQL Server]Statement(s) could not be prepared. (8180)")
You may notice that the statement is not strictly DB-API 2.0 compliant.
pyodbc has an extension that allows you to supply arguments directly,
instead off putting them inside a tuple. I have tried with and without a
tuple - the result is the same.
Any assistance will be appreciated.
