pyodbc

问题 I have a Python program that connects to an MSSQL database using an ODBC connection. The Python library I'm using is pypyodbc. Here is my setup: Windows 8.1 x64 SQL Server 2014 x64 Python 2.7.9150 PyPyODBC 1.3.3 ODBC Driver: SQL Server Native Client 11.0 The problem I'm having is that when I query a table with a varchar(max) column, the content is being truncated. I'm new to pypyodbc and I've been searching around like crazy and can't find anything on how to prevent this from happening in

问题 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.

问题 I have a program inserting a bunch of data into an SQL database. The data consists of Reports , each having a number of Tags . A Tag has a field report_id , which is a reference to the primary key of the relevant Report . Now, each time I insert the data, there can be 200 Reports or even more, each maybe having 400 Tags . So in pseudo-code I'm now doing this: for report in reports: cursor_report = sql('INSERT report...') cursor_report.commit() report_id = sql('SELECT @@IDENTITY') for tag in

问题 this seems like a basic function, but I'm new to Python so maybe I'm not googling this correctly. In Microsoft SQL Server, when you have a statement like SELECT top 100 * FROM dbo.Patient_eligibility you get a result like Patient_ID | Patient_Name | Patient_Eligibility 67456 | Smith, John | Eligible ... etc. Etc. I am running a connection to SQL through Python as such, and would like the output to look exactly the same as in SQL. Specifically - with column names and all the data rows

问题 I'm using PyODBC for SQL Server 2008 database engine and it works well. I can retrieve records and execute procedures and views with no problem. My issue is I can't connect to SQL Server 2008 Analysis Server using PyODBC. Following list shows what I've tried: cnxn = pyodbc.connect(r'Driver={SQL Server};Server=127.0.0.1;Database=DB1;Trusted_Connection=yes;') And cnxn = pyodbc.connect('DRIVER={SQL Server};SERVER=127.0.0.1;DATABASE=DB1;Trusted_Connection=yes;UID=TB\\user;PWD=123123') What's the

问题 I'm using Python to read and write SAS datasets, using pyodbc and the SAS ODBC drivers. I can load the data perfectly well, but when I save the data, using something like: cursor.execute('insert into dataset.test VALUES (?)', u'testing') ... I get a pyodbc.Error: ('HY004', '[HY004] [Microsoft][ODBC Driver Manager] SQL data type out of range (0) (SQLBindParameter)') error. The problem seems to be the fact I'm passing a unicode string; what do I need to do to handle this? 回答1: Do you know what

问题 I am pulling data from a MSSQL db using pyodbc which returns my data set in a list. This data then needs to be transferred into a MySQL db. I have written the following stored procedure in MySQL.
