Passing table name as a parameter in pyodbc

问题 I am trying to pass a table name in pyodbc as a parameter to access data from ms sql 2005. I've tried to substitute it with ? but it never works. I would be glad to receive any advice on how to accomplish this. 回答1: Since you are using pyodbc, I assume you are not calling a SPROC. I recommend building your SQL string in python and then passing it to SQL to execute. import pyodbc dbconn = pyodbc.connect(ConnectionString) c = dbconn.cursor() j = 'table1' #where table1 is entered, retreived, etc

Is it possible to have SQL Server convert collation to UTF-8 / UTF-16

由 ￣綄美尐妖づ 提交于 2019-12-06 19:23:54
问题 In a project I am working on my data is stored in SQL Server, with the collation Danish_Norwegian_CI_AS . The data is output'ed through FreeTDS and ODBC, to python that handles the data as UTF-8. Some of the characters, like å, ø and æ, are not being coded correctly, causing the project progress to grind to a halt. I spent a couple of hours reading about the confusing world of encodings, collation and code-pages, and feel like I have gotten a better understanding of the entire picture. Some

Convert a pyodbc.Row to a string

由 久未见 提交于 2019-12-06 16:32:00
I need to convert a pyodbc.Row to a string. The internet provides several suggestions, none of which seem to work for me. row = cursor.fetchone() #unicodedata.normalize('NFKD', row).encode('ascii','ignore') #TypeError: must be unicode, not pyodbc.Row #row.fieldname.encode('utf8') #AttributeError: 'pyodbc.Row' object has no attribute 'fieldname' tblName = str(row) tblName.replace("text:u","").replace("'","") tblName = tblName.encode('utf-8') print tblName The above either give an error (shown in comment) or seems to have no effect as shown in the output here: (u'myTableName', ) # print tblName

I am trying to use pyodbc cursor execute the right way to prevent injection attacks, as suggested here: what does ? mean in python pyodbc module My code is as follows: query = """\ SELECT ?,count(*) FROM ? WHERE ?=? """, ('date', 'myTable', 'date', '2017-05-08') cursor.execute(query) And I get an error: TypeError: The first argument to execute must be a string or unicode query.

How do I access AS/400 using SQLAlchemy?

由 此生再无相见时 提交于 2019-12-06 13:15:23
问题 Short version: Please tell me how to connect to AS/400s via SQLAlchemy. Long version My ultimate goal is to join data from SQL Server and AS/400 to be displayed in a Flask Python application. My approach has been to get the data from each database into Pandas dataframes, which can then be joined and output as JSON. If anyone has a better approach, feel free to leave a comment. The problem with the way I'm trying to do this is that Pandas.read_sql_query() relies on SQLAlchemy, and getting
