Extension talk:External Data/Archive 2017 to 2018

Not Working
any idea why? it's installed in Special:Version, but it doesn't show anything (xml works fine): http://www.komentarz.org/pl/test


 * You also need to set the "data" parameter. Yaron Koren 22:36, 2 February 2011 (UTC)

so if this is my xml feed, what data should i type? name of the xml node? http://www.komentarz.org/smw/api.php?action=query&list=threads&format=xml


 * I don't want to sound rude, but - have you read the documentation? Yaron Koren 00:59, 4 February 2011 (UTC)

sure, i found this fragment but i think a clear example of getting rss xml feed in documentation would be helpful. i still can't get it to work.your extension would be a perfect rss reader (other extension doesn't work or are unstable): For data from XML sources, the variable names are determined by both tag and attribute names. For example, given the following XML text:  red the variable type would have the value Apple, and the variable color would have the value red. Similarly, the following XML text would be interpreted as a table of values defining two variables named type and color:  red  brown


 * Well, in any case, a more reasonable value for "data=" would be "data=thread=thread,subject=subject". Yaron Koren 23:37, 4 February 2011 (UTC)

Sort results
Any way to sort results returned from #get_db_data?


 * I don't think so, but it might definitely be worthwhile to have a way for users to add an "ORDER BY" command to the SELECT call... Yaron Koren 01:00, 4 February 2011 (UTC)


 * It certainly would! Could you provide that? Matheus Garcia 17:53, 15 February 2011 (UTC)

SQLSRV vs MSSQL
I am not sure how to ask this correctly. I have upgraded to PHP 5.3.5 which no longer supports mssql (from what I can tell). So I have downloaded the Microsoft support for SQL Server and PHP and added the necessary information to php.ini.

Does MediaWiki support the interface to SQL Server through the new library sqlsrv. The mediawiki includes/db directory has the DatabaseMssql.php file, but the interface is mssql_function calls and not sqlsrv_function calls.

So am I out of luck using PHP 5.3.5 and MS SQL Server?

 * Hi, I really don't know anything about MediaWiki's suppport for SQLServer, but it sounds like you might be out of luck - at least until MediaWiki's support gets improved. You could always submit a bug report for it... Yaron Koren 22:27, 18 February 2011 (UTC)


 * Well a little further research this morning and I found a Bugzilla Report 22093 which discussed the new interface to Microsoft SQL Server. .  With my limited ability I was able to find the new code in the 1.17 trunk (includes/db/DatabaseMssql.php.  It is the same file name as before, but different guts.  I have not been able to find a 1.16 version and I can't get the 1.17 version to work under 1.16 because of some interface changes.  I have emailed Ryan Biesemeyer for any further suggestions with 1.16... Wolcott 15:25, 21 February 2011 (UTC)


 * Ryan Biesemeyer responded that MediaWiki team still has some concerns with the compatibility. He will attempt to see what it would take to back port to 1.16, but no promises.  I have backport a minimalistic number of functions to make it work with my requirements ... Wolcott 17:19, 22 February 2011 (UTC)

get_db_data - Data parsing
I wasn't thinking how you parsed the data section before trying to attempt and format a date via the database. Issuing the query below via SQL Server produces Feb 22, 2011 instead of 2011-02-17T12:04:00Z

SELECT Title_Txt, CONVERT(VARCHAR(12), Documentation_Rev_Dt, 107) AS Rev_Dt FROM Tool WHERE Acronym_Txt ='ITEM'

But obviously trying to perform it via get_db_data the parser messes things up because it uses the comma to parse on KeyValue mappings.

Any thought to allow us to define the seperator? Would it be better to define it as a localsettings token and thus make it global or add it to #get_db_data: as seperator so that it is unique to that query. Wolcott 18:49, 22 February 2011 (UTC)


 * Ah - good point. Let me look into it. Maybe with some simple parenthesis-matching, it'll still be possible to use commas. Yaron Koren 21:01, 22 February 2011 (UTC)


 * Yaron not a big hurry. I am able to use the #time parser to format the date the way I want to present it. Wolcott 01:41, 27 February 2011 (UTC)
