pyodbc

问题 I already tried a couple of drivers: pymsql, pyobdc and still have issue with format single quote in SQL. Examples of code below: CASE 1. import pyodbc UPDATE_SQL3 = """ UPDATE STATION SET STATION_NAME = ?, STATION_TITLE = ?, ACTIVE = ? WHERE STATION_ID = ? """ conn = pyodbc.connect('DRIVER={SQL Server};SERVER=local;DATABASE=DB;UID=me;PWD=pass') cursor = conn.cursor() cursor.execute(UPDATE_SQL3 % (name, title, active, id )) This code doesn't compile: "not all arguments converted during string

问题 I am using pyodbc to update an Access database. I need the functionality of an UPSERT. ON DUPLICATE KEY UPDATE doesn't exist in Access SQL, and REPLACE is not an option since I want to keep other fields. There are a lot of suggestions out there how to solve that, so this is the solution which I put together: for table_name in data_source: table = data_source[table_name] for y in table: if table_name == "whatever": SQL_UPDATE = "UPDATE {} set [Part Name] = '{}', [value] = {}, [code] = {},

问题 I have just installed 64-bit microsoft office on a new computer and also installed 64bit python 3.6. I'm trying to connect to an access database with my python script, however I keep getting the following error which suggests I have the 32bit ODBC driver instead of the 64bit driver? Any ideas on how to connect without having to install 32bit MS Office and 32bit Python? This is the error message I get: cnxn = pyodbc.connect(connstr) pyodbc.Error: ('IM002', '[IM002] [Microsoft][ODBC Driver

问题 In a Python script with pyodbc, I am trying to connect to a still used Access 97 database on our network but I have problems to get the connection (or the connection string) to work. I keep getting the following error: pyodbc.Error: ('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnectW)') This is my connection string which fails with above mentioned error: conn = pyodbc.connect('Driver={Microsoft Access Driver (

问题 Is there a way to get pyODBC v3.0.10 to look for the unixODBC driver, instead of the iODBC driver it seems to want to look for? My understanding is that pyODBC v3.0.10 is supposed to do this by default, while versions prior to v3.0.7 required a manual edit to the setup.py file (see reference here). One more clue, I ran this code to list my ODBC sources, and it returned nothing: sources = pyodbc.dataSources() dsns = list(sources.keys()) dsns.sort() sl = [] for dsn in dsns: sl.append('%s [%s]'

问题 Instead of editing the sql-string when i want to change which column to write to i want to use a variable.. This seems to work. I get no error, but the database is not updated... What is wrong with this? cnxn = pyodbc.connect('DRIVER=FreeTDS;SERVER=dkvmsql08;PORT=1433;DATABASE=dingdong_test;UID=dac\svc-dingdong;PWD=c90346KJHjkhg&%dad742210a3d6fd4436c;T$ cur = cnxn.cursor() name = Dennis cur.execute("UPDATE dbo.timestamp set cur.execute("UPDATE dbo.test set ?=1 where id=?",name, row.id) 回答1:

问题 I am trying to use pandas.read_sql_table to get data from MS SQL Server (the server is on a network). I use Windows authentication to access the server. Pandas read_sql_table takes a SQL Alchemy connection as an argument for “connection.” I am having a difficult time finding an example that combines: SQL Alchemy MS SQL Server DSN (the “preferred” specification according to SQL Alchemy) Windows authentication I’ve consulted SQL Alchemy, which shows an example using SQL authentication, but not

问题 I've been trying to parse a text file (opened with parameter encoding='utf8') and insert extracted values into an mdb database using pyodbc module. I have tried the code below: for line in fp: tokens = line.split('\t') tokens[4] = tokens[4][:len(tokens[4])-1] #to avoid the \n tokens[1] = tokens[1][1:] #to remove the 'u' from the beginning of utf8 characters like u'\u0622' content = conn.execute("INSERT INTO Entries (PForm, WForm, Code, Freq, Pattern) VALUES ("+tokens[0]+","+tokens[1]+","
