Re: [Tutor] please help with sqlite replace function
"aivars" <[EMAIL PROTECTED]> wrote Yes it seems you are right. The ActiveState python version I have installed have sqlite 2.3.2 only. I find it strange. Why? SQLite is a separate product. Python bundled the then current version in its standard distribution, but time has moved on. You have apparently installed a more recent version of SQLite. I see that on a python website there is is a new version Python26 2.6 may or may not have the same version as you but regardless you should be able to get the older version of Python to work with the newer SQLite instal;l, provided the newer version has a Python library available - which it usually has. Mark Hammonds PythonWin to get other things for windows? Or maybe I will reinstall ActiveState Python25 and install Python25 from the official website I don't thing the vanilla Python will make any difference. SQLite is bundled with Python not with ActiveState. Copying dll to c:\python25\DLLs directory did not help - it still shows version sqlite version 2.3.2. which I also do not understand why I think you might need to install more than the DLL. Check the SQLite web site for a new Ptython interface and install that version. Alan G. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] please help with sqlite replace function
John, just to add to my previous post. after copying sqlite3.dll (3.6.2) version into Python25\DLLs directory and running import sqlite3 dir(sqlite3) >>> sqlite3.version '2.3.2' >>> sqlite3.version_info (2, 3, 2) >>> sqlite3.sqlite_version_info (3, 6, 2) >>> sqlite3.sqlite_version '3.6.2' and now my scrip happily runs with sqlite replace function. I am just curious why there are so many different version properties and why now they differ from sqlite3.version? Of course it seems Python now is running sqlite version 3.6.2 since my script accepts replace function Thanks, Aivars 2008/11/7 aivars <[EMAIL PROTECTED]>: > Thanks, John, > Yes it seems you are right.

Re: [Tutor] please help with sqlite replace function
Thanks, John, Yes it seems you are right. The ActiveState python version I have installed have sqlite 2.3.2 only. I find it strange. I see that on a python website there is is a new version Python26 relesed. Should i go on and install Python26? I understand that I can install pure Python from python website and after that I can install Mark Hammonds PythonWin to get other things for windows? Or maybe I will reinstall ActiveState Python25 and install Python25 from the official website Copying dll to c:\python25\DLLs directory did not help - it still shows version sqlite version 2.3.2. which I also do not understand why Re user defined function - it is one of the ways to go probably quickest but I would like to have newer version of sqlite being already with python I am noob in Python still Thanks for your input Aivars 2008/11/6 John Fouhy <[EMAIL PROTECTED]>: > 2008/11/7 aivars <[EMAIL PROTECTED]>: >> I use python 2.5.2.2 (activestate), WinXP, sqlite version 3.6.2 > > Hi Aivars, > > I believe python has its own built-in sqlite, rather than using the > version you installed independently.

2008/11/7 aivars <[EMAIL PROTECTED]>: > I use python 2.5.2.2 (activestate), WinXP, sqlite version 3.6.2 Hi Aivars, I believe python has its own built-in sqlite, rather than using the version you installed independently. So it is possible that the python version of sqlite is older than 3.6.2 and does not yet have the replace() function. (run 'import sqlite3' and then examine 'sqlite3.sqlite_version' to see what version you are using) You could try replacing sqlite3.dll in your python25\dlls directory with the DLL from your sqlite installation (make a backup first :-) ). Alternatively, you could define the replace() function in python and then add it to your database: see http://www.initd.org/pub/software/pysqlite/doc/usage-guide.html#creating-user-defined-functions .

[Tutor] please help with sqlite replace function
Hello, I am stuck now. I have a sqlite database with a table calendar (which is an auxilary calendar table containing dates, years, months, days) >From sqlite prompt I can run the following query without any problem: SELECT replace( datums,'-','' ) FROM calendar where Y='2008' and M='5' It gives me back date strings in the format MMDD. But when I run it from the python script it gives me the following error: sqlite3.OperationalError: no such function: replace. Script is simple as follows: import sqlite3 spath=r'e:\pythonexamples\aivars2.db' sql="SELECT replace(datums,'-','') FROM Calendar where Y='2008' and M='5'" cn=sqlite3.connect(spath) for row in cn.execute(sql): print row[0] When I run the script without the replace function in select statement it runs OK. I use python 2.5.2.2 (activestate), WinXP, sqlite version 3.6.2 Thanks for any tip. maybe I should ask this to sqlite mailing list?
