pyodbc

问题 I downloaded Python 2.7 ( python-2.7.1.amd64.msi ) and pyodbc, the python extension module for connecting to DB2 database (i.e. pyodbc-2.1.8.win-amd64-py2.7.exe ). I wrote sample script as shown below. import csv import pyodbc conn = pyodbc.connectpyodbc.connect('DRIVER={DB2};SERVER=localhost;DATABASE=DBT1;UID=scott;PWD=tiger;') curs = conn.cursor() curs.execute('select count(edokimp_id) from edokimp') print curs.fetchall() The script throws following error pyodbc.Error: ('IM002', '[IM002]

Installed msodbcsql17 in ubuntu 19.04 like described here. I tried all the suggestions from here and here. I did the analysis like described here. With pyodbc 4.0.26, it is possible to check the driver in the anaconda

问题 I am trying to execute SQL query within Access database using PYODBC and I get following error: pyodbc.Error: ('07002', '[07002] [Microsoft][ODBC Microsoft Access Driver] Too few parameters. Expected 1. (-3010) (SQLExecDirectW)') The problem is that I am not using any additional parameters. Here is the code: access_con_string = r"Driver={};Dbq={};".format(driver, base) cnn = pyodbc.connect(access_con_string) db_cursor = cnn.cursor() expression = """SELECT F_ARODES.ARODES_INT_NUM, F_ARODES

问题 What is a good pywin32 odbc connector documentation and tutorial on the web? 回答1: The only 'documentation' that I found was a unit test that was installed with the pywin32 package. It seems to give an overview of the general functionality. I found it here: python dir\Lib\site-packages\win32\test\test_odbc.py I should also point out that I believe it is implements the Python Database API Specification v1.0, which is documented here: http://www.python.org/dev/peps/pep-0248/ Note that there is

问题 I'm writing a Python program that selects some data from a Microsoft Access mdb file using PyODBC. I need to discover the column names of several different tables. In SQL Server, this can be accomplished by using a query like SELECT c.name FROM sys.columns c, sys.tables t WHERE c.object_id = t.object_id AND t.name = tableName But that query doesn't work in Access. With SELECT MSysObjects.Name FROM MSysObjects WHERE (((MSysObjects.Flags)=0) AND ((MSysObjects.Type)=1)) ORDER BY MSysObjects.Name

问题 I'm running a series of complex sql queries in python and it involves temp tables. My auto-commit method doesn't seem to be working to retrieve the data from the temp table.
