pyodbc

问题 I am connecting to an MS SQL Server db from Python in Linux. I am connecting via pyodbc using the FreeTDS driver. When I return a money field from MSSQL it comes through as a float, rather than a Python Decimal. The problem is with FreeTDS. If I run the exact same Python code from Windows (where I do not need to use FreeTDS), pyodbc returns a Python Decimal. How can I get back a Python Decimal when I'm running the code in Linux? 回答1: You could always just convert it to Decimal when it comes

问题 Edit: Apparently my connection (PYODBC) is reading in the NULLs as 0s. I'd like to correct this on a "higher" level as I'll be reading in lots of SQL files. I can't find anything in the documentation to prevent this. Any suggestions? I am importing a SQL file/query as a string and then using pd.read_sql to query my database. In SQL Server I can do calculations between NULL values which results in a NULL value, however, in Python, this errors out my script. Query ran in SQL Server: SELECT

问题 I am trying to figure out how to pass a list as a parameters through a where statement in SQL, I can not program what I am looking for, but below is what I am looking for. This is what I would do for one parameter.... x = 1 sql = """Select t1,t2,t3,t4 from database where t1= ? """ cur.execute(sql,x) Example of what I need X = [1,2,3,4] Select t1,t2,t3,t4 from database where t1= 1 Select t1,t2,t3,t4 from database where t1= 2 Select t1,t2,t3,t4 from database where t1= 3 Select t1,t2,t3,t4 from

问题 Using python 2.7 and the MS odbc driver through pyodbc. My connection string looks like this: mssql+pyodbc://myuser:mypass@serverip/instancename?driver=ODBC+Driver+11+for+SQL+Server I am getting login failed. However if I use the same credentials and "serverip\instancename" in the microsoft sql server management studio, I can connect. The thing that is driving me crazy is a couple of days ago, this same connection string worked for me but to a different sql server instance on the same machine

问题 I have a SQL Server stored procedure that returns 3 separate tables. How can I store each of this table in different data-frame using pandas? Something like: df1 - first table df2 - second table df3 - third table Where should I start looking at? Thank you import pandas as pd import pyodbc from datetime import datetime param = datetime(year=2019,month=7,day=31) query = """EXECUTE [dbo].PythonTest_USIC_TreatyYear_ReportingPackage @AsOFDate = '{0}'""".format(param) conn = pyodbc.connect('DRIVER=

问题 I am running on Windows 7, Python 2.7 and Microsoft Access 2013.

问题 I can not get a valid string from an MSSQL server into python. I believe there is an encoding mismatch somewhere. I believe it is between the ODBC layer and python because I am able to get readable results in tsql and isql. What character encoding does pyodbc expect? What do I need to change in the chain to get this to work? Specific Example Here is a simplified python script as an example: #!/usr/bin/env python import pyodbc dsn = 'yourdb' user = 'import' password = 'get0lddata' database =
