pyodbc

I'm trying to install PyODBC on Heroku, but I get fatal error: sql.h: No such file or directory in the logs when pip runs. How do I fix this error? To follow up on the answer below... Example for Ubuntu: sudo apt-get install unixodbc unixodbc-dev Example for CentOS: sudo yum install unixODBC-devel On Windows: conn = pyodbc.connect('DRIVER={SQL Server};SERVER=yourserver.yourcompany.com;DATABASE=yourdb;UID=user;PWD=password') On Linux: conn = pyodbc.connect('DRIVER={FreeTDS};SERVER=yourserver.yourcompany.com;PORT=1433;DATABASE=yourdb;UID=user;PWD=password;TDS_VERSION=7.2') You need the unixODBC

I am attempting to use pyobdc to read data from a paradox database, and I keep getting the following error when attempting to connect to the database: pyodbc.Error: ('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnect)') I have tried to create new DNS links for the database but it has not helped what so ever. My system links looks like this: My code is: import os import sys import time import pyodbc LOCATION = "c:\Users\Marcello\Desktop\DATA\ScorMonitor.db" cnxn = pyodbc.connect(r"Driver={{Microsoft Paradox Driver

from pandas import DataFrame import pyodbc cnxn = pyodbc.connect(databasez) cursor.execute("""SELECT ID, NAME AS Nickname, ADDRESS AS Residence FROM tablez""") DF = DataFrame(cursor.fetchall()) This is fine to populate my pandas DataFrame. But how do I get DF.columns = ['ID', 'Nickname', 'Residence'] straight from cursor ? Is that information stored in cursor at all? You can get the columns from the cursor description: columns = [column[0] for column in cursor.description] phoenix10k Recent pandas have a higher level read_sql functions that can do this for you import pyodbc import pandas as pd

The following works: import pyodbc pyodbc.connect('DRIVER={FreeTDS};Server=my.db.server;Database=mydb;UID=myuser;PWD=mypwd;TDS_Version=8.0;Port=1433;') The following fails: import sqlalchemy sqlalchemy.create_engine("mssql://myuser:mypwd@my.db.server:1433/mydb?driver=FreeTDS& odbc_options='TDS_Version=8.0'").connect() The error message for above is: DBAPIError: (Error) ('08001', '[08001] [unixODBC][FreeTDS][SQL Server]Unable to connect to data source (0) (SQLDriverConnectW)') None None Can someone please point me in the right direction? Is there a way I can simply tell sqlalchemy to pass a

I use the following code in Python (with pyodbc for a MS-Access base). cursor.execute("select a from tbl where b=? and c=?", (x, y)) It's Ok but, for maintenance purposes, I need to know the complete and exact SQL string send to the database. Is it possible and how ? It differs by driver. Here are two examples: import MySQLdb mc = MySQLdb.connect() r = mc.cursor() r.execute('select %s, %s', ("foo", 2)) r._executed "select 'foo', 2" import psycopg2 pc = psycopg2.connect() r = pc.cursor() r.execute('select %s, %s', ('foo', 2)) r.query "select E'foo', 2" joseph You can use print cursor._last

I am trying to retrieve data from an SQL server using pyodbc and print it in a table using Python. However, I can only seem to retrieve the column name and the data type and stuff like that, not the actual data values in each row of the column. Basically I am trying to replicate an Excel sheet that retrieves server data and displays it in a table. I am not having any trouble connecting to the server, just that I can't seem to find the actual data that goes into the table. Here is an example of my code: import pyodbc cnxn = pyodbc.connect('DRIVER={SQL Server};SERVER=SQLSRV01;DATABASE=DATABASE
