pyodbc

问题 I am trying to insert a list of tuples into an MS SQL table via pyodbc with Python 3. This works: conn_string = (('DRIVER=FreeTDS;' 'SERVER={};' 'PORT=1433;' 'DATABASE={};' 'UID={};' 'PWD={};' 'TDS_Version=8.0;') .format(server, db, user, pwd)) sql = """ insert into Table1(field1, field2, field3) values (?, ?, ?) """ cursor.executemany(sql, [('1175B57E-7A10-4BAC-B22E-457C8266C0F2', '1D111FA5-A65D-4F77-A3AB-78B80BAF0C0B', 2), ('C60FA1C9-7656-4EBF-A577-44CBF0C641F4', '365FB706-9F7F-4ED4-AB88

问题 I am trying to connect to an Access 2007 database with the following connection string. conn = pyodbc.connect("Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=<C:\Users\JSeinfeld\Desktop\Backup databases\Database_6.7.accdb>;") I get this error: Traceback (most recent call last): File "", line 1, in conn = pyodbc.connect("Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=;") Error: ('HY000', "[HY000] [Microsoft][ODBC Microsoft Access Driver]General error Unable to open registry key

问题 This has been a long running issue for me. I have a proprietary database that I cannot change and many of the tables have fields which are defined as e.g. decimal(12, 4). When I try to pull data from such a table on ubuntu 12.04 using pyodbc/freeTDS like this... import pyodbc connection_string = 'DRIVER={FreeTDS};DSN=<myDSN>;UID=<my_user>;PWD=<my_password>;' conn = pyodbc.connect(connection_string) cur = conn.cursor() cur.execute('SELECT myfield FROM mytable') for row in cur.fetchall(): print

问题 Is it possible to specify where pyodbc looks for the SQL driver? I have a python application which needs the 'SQL Native Client 10.0' driver to connect to a SQL database. So my connection string looks like: dsn = 'DRIVER={SQL Server Native Client 10.0};SERVER=localhost;DATABASE=mydatabase;UID=sa;PWD=mypasswd' con = pyodbc.connect(dsn) with con: #do something One major disadvantage (at least for me) is, that the SQL Native Client 10.0 driver needs to be installed on the machine and that

问题 I am able get some data from the ms access by some query, but I am not able to store data into any table, for example: import sys, os, pyodbc conn_str = ( r'DRIVER={Microsoft Access Driver (*.mdb, *.accdb)};' r'DBQ=C:/Users/vlcek/Desktop/pokusdb.accdb;' ) connection = pyodbc.connect(conn_str) cursor = connection.cursor() sql="Insert into people (user_id, Name, Surname) values (27, 'Peter','Jackson')" cursor.execute(sql) I do have the table "people" already in database... I am getting this

问题 I have a pandas data frame oParameterData which I have built querying on Hadoop using Hive ODBC connection. I am using it to populate a Python dictionary called oParameter import pyodbc import pandas oConnexionString = 'Driver={ClouderaHive};[...]' oConnexion = pyodbc.connect(oConnexionString, autocommit=True) oConnexion.setencoding(encoding='utf-8') oQueryParameter = "select * from my_db.my_table;" oParameterData = pandas.read_sql(oQueryParameter, oConnexion) oCursor = oConnexion.cursor()

问题 I'm trying to connect to a MS Access Database (.accdb file) via python. I used pyodbc to do this connection: import pyodbc conn = pyodbc.connect("DRIVER = {Microsoft Access Driver (*.mdb, *.accdb)}; DBG=C:\\test_db.accdb") However, I got the following error: ('IM002, '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnect)') I went to the ODBC Data Source Administrator and when I tried to configure or remove the Driver I got

问题 I know there is many topics on this but i think this is much specific. I get the current code for audit purpose: import pandas as pd import pyodbc query = """ --Top 50 high total CPU Queries SELECT TOP 50 'High CPU Queries' as Type, serverproperty('machinename') as 'Server Name', isnull(serverproperty('instancename'),serverproperty('machinename')) as 'Instance Name', COALESCE(DB_NAME(qt.dbid), DB_NAME(CAST(pa.value as int)), 'Resource') AS DBNAME, qs.execution_count as [Execution Count], qs

问题 I'm trying to use pyodbc to connect to a local copy of a SQL Server 2008 database (it connects to the remote production database just fine). However, when I try connecting to the local copy using the following command: pyodbc.connect('DRIVER={SQL Server};SERVER=localhost;DATABASE=mydb;UID=me;PWD=pw') the connection fails with the following error message: pyodbc.Error: ('08001', '[08001] [Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied. (17)

问题 So I'm currently linking Python with SQL to pull out customer information. Unfortunately, I'm getting some errors with regards to SQL. I am trying to use the LIKE operator, and the % wildcard, but I keep getting errors because Python does not like %. As a result, it pretends that variable between the %s do not exist. Here's what I mean: SELECT custnbr, firstname, middleint, lastname FROM lqppcusmst WHERE custnbr = ? AND firstname LIKE ? Right now, I'm just testing it out, so I'm just using
