Hello,
I have a string:
INSERT INTO mailboxes (`name`, `login`, `home`, `maildir`, `uid`,
`gid`, `password`) VALUES (%s, %s, %s, %s, %i, %i, %s)
that is passed to a MySQL cursor from MySQLdb:
ret = cursor.execute( sql, paras)
paras is:
('flindner', 't****@florian-lindner.de', '/home/flindner/', '/home/
flindner/Mail/test', 1001, 1001, '123')
But that gives me an error:
Traceback (most recent call last):
File "account.py ", line 188, in ?
main()
File "account.py ", line 33, in main
execute(action, account_type, options)
File "account.py ", line 129, in execute
executeSQL(sql, options.usernam e, options.login, options.home,
options.directo ry, options.uid, options.gid, options.passwor d)
File "/home/flindner/common.py", line 29, in executeSQL
ret = cursor.execute( sql, paras)
File "/usr/lib/python2.4/site-packages/MySQLdb/cursors.py", line
148, in execute
query = query % db.literal(args )
TypeError: int argument required
I don't see errors in the format string or some other problem....
What's wrong?
Thanks,
Florian

You should be using '?' for parameter bindings in your sql string not
python format specifiers (you are after all writing sql here not
python).
INSERT INTO mailboxes (`name`, `login`, `home`, `maildir`, `uid`,
`gid`, `password`) VALUES (?, ?, ?, ?, ?, ?, ?)

Sorry Tim, but that isn't correct:

MySQLdb.param style

Florian, what happens when you replace your %i with %s?

Not really... The MySQLdb adapter converts all parameters to
properly delimited STRINGS (I don't know of any SQL system that passes
/binary/ numerics). But MySQLdb also uses Python % formatting to then
I'd say the opposite: only poorly implemented systems convert numeric
arguments to text.
*Real* bound variables are passed as pointers. The SQL sentence can be
prepared and re-used with different sets of values several times, without
having to re-parse it again and again.
If the MySQLdb adapter actually converts and inserts the arguments itself
into the supplied SQL sentence, generating a new string for each call,
this advantage -and many others- are cancelled, defeating the purpose of
bound variables.

I'm using the mx.ODBC.Windows package in order to read/write a MSAccess

using the default "datetimeformat" (i.e. DATETIME_DATETIMEFORMAT) as
suggested. The date columns in the MSAccess database have "Short Date"
format.
When I read a DATE item everything works fine, like:

hello,
I finally got some code to push a pickled list into a database table.
but now the problem is technically complex although possible to solve.
the problem is that I can nicely pickle and store lists in a blob
field with the help of dumps() for picklling into a string and then
passing the string to the blob.
I am also able to get back the string safely and do a loads() to
unpickle the object.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
