MySQL Insert

[maestroQC]

Hi,

Its one of those days. I cannot solve this. Any help would be greatly
appreciated!
When I execute this:

class Db(object):
def insertAccount(self, date, accountNumber, description,
openingBalance):
dec = decimal.Decimal(openingBalance)
db = MySQLdb.connect(host="localhost", user="dumb",
passwd="dumber", db="rdc")
cursor = db.cursor()
cursor.execute("INSERT INTO es_accounts (dateCreated,
accountNumber, description, openingBalance) VALUES (%s, %s, %s, %d)",
(date, accountNumber, description, dec))

I get this error:
Traceback (most recent call last):
File "main.py", line 59, in <module>
main()
File "main.py", line 40, in main
dbObj.insertAccount(dateTo, item[0], item[1], item[8])
File "C:\projects\workspace\INYR_ES_0.1\src\db.py", line 19, in
insertAccount
cursor.execute("INSERT INTO es_accounts (dateCreated,
accountNumber, description, openingBalance) VALUES (%s, %s, %s
, %d)", (date, accountNumber, description, dec))
File "c:\python25\lib\site-packages\MySQLdb\cursors.py", line 151,
in execute
query = query % db.literal(args)
TypeError: int argument required

My table is defined as:
CREATE TABLE es_accounts (
id int(6) not null auto_increment,
dateCreated date DEFAULT '0000-00-00',
accountNumber int(6) not null,
description varchar(255) not null,
openingBalance decimal(15,8) NOT NULL DEFAULT 0.00000000,
primary key (id)
);

TIA

cursor.execute("INSERT INTO es_accounts (dateCreated,
accountNumber, description, openingBalance) VALUES (%s, %s, %s
, %d)", (date, accountNumber, description, dec))
File "c:\python25\lib\site-packages\MySQLdb\cursors.py", line 151,
in execute
query = query % db.literal(args)
TypeError: int argument required

The placeholder for query parameters in MySQLdb is always %s, regardless
of the data type the actual value might have.

HTH,

The problem is your %d in Values, and then using a Decimal type to feed
it. Depending on the type of your openingBalance field, you may want to
change the %d to %s, or change dec to int(dec), or change the %d to %f
and change dec to float(dec). My experience with the Decimal type is
limited, so there may be other options as well.

How embarassing. My previous post is not correct in it's explanation,
unless there is some way to tell Decimal not to allow int coercion...

--> from decimal import Decimal
--> n10_25 = Decimal('10.25')
--> n10_25
Decimal("10.25")
--> "%d" % n10_25
'10'

About the only thing it had even partially right is not using %d, as it
will truncate the fractional part of your opening balance. As far as
why you are getting that error, I now have no idea, and I apologize for
any confusion created by my error.

Thanks for the information.
However I must stick to decimal since I'm dealing with monetary
values.
I loose the decimals with int and float has only supports one decimal
place.

I tried as you suggested to use the %s instead of the %d to no avail.

Thanks to all for your time and patience with this!
The insert is working fine based on the suggestions in this thread.

I now have another problem that should be resolved with a regular
expression to remove currency formatting before inserting into the db.
