cx-oracle

问题 So I found Help installing cx_Oracle but am still stuck. I downloaded the latest instantclient from oracle, and set ORACLE_HOME to the location of the extracted files (both direct and with a bin folder between the ORACLE_HOME value and the files), but easy_install is popping an error when running setup.py saying it can't locate the Oracle include files. I did notice that only the 11g dll is in the folder, do I need all 3 drivers present for setup to complete? If so, where do I even get them?

问题 Here's what I did: I'm on Windows XP SP3 I already had Python 2.7.1 installed. I downloaded instantclient-basic-nt-11.2.0.3.0.zip , unzipped it, and put it in C:\Program Files\Oracle\instantclient_11_2 . I added this path to the Windows Path environment variable. I created a new environment variable ORACLE_HOME holding this path as its value. I installed cx_Oracle-5.1.2-11g.win32-py2.7.msi . And on running import cx_Oracle all I get is Traceback (most recent call last): File "<string>", line

问题 I am a Python newbie, I am having troubles in the use of bind variables.

问题 I have some monthly weather data that I want to insert into an Oracle database table but I want to insert the corresponding records in a batch in order to be more efficient. Can anyone advise as to how I'd go about doing this in Python? For example let's say my table has four fields: a station ID, a date, and two value fields. The records are uniquely identified by the station ID and date fields (composite key). The values I'll have to insert for each station will be kept in a list with X
