How to see the real SQL query in Python cursor.execute using pyodbc and MS-Access

由 ぃ、小莉子 提交于 2019-11-27 00:20:48
问题 I use the following code in Python (with pyodbc for a MS-Access base). cursor.execute("select a from tbl where b=? and c=?", (x, y)) It's Ok but, for maintenance purposes, I need to know the complete and exact SQL string send to the database. Is it possible and how ? 回答1: It differs by driver. Here are two examples: import MySQLdb mc = MySQLdb.connect() r = mc.cursor() r.execute('select %s, %s', ("foo", 2)) r._executed "select 'foo', 2" import psycopg2 pc = psycopg2.connect() r = pc.cursor()

python pip specify a library directory and an include directory

由 删除回忆录丶 提交于 2019-11-27 00:02:16
I am using pip and trying to install a python module called pyodbc which has some dependencies on non-python libraries like unixodbc-dev, unixodbc-bin, unixodbc. I cannot install these dependencies system wide at the moment, as I am only playing, so I have installed them in a non-standard location. How do I tell pip where to look for these dependencies ? More exactly, how do I pass information through pip of include dirs (gcc -I) and library dirs (gcc -L -l) to be used when building the pyodbc extension ? pip has a --global-option flag You can use it to pass additional flags to build_ext .

Get data from pandas into a SQL server with PYODBC

由 ≡放荡痞女 提交于 2019-11-26 17:43:50
问题 I am trying to understand how python could pull data from an FTP server into pandas then move this into SQL server. My code here is very rudimentary to say the least and I am looking for any advice or help at all. I have tried to load the data from the FTP server first which works fine.... If I then remove this code and change it to a select from ms sql server it is fine so the connection string works, but the insertion into the SQL server seems to be causing problems. import pyodbc import
