Empty password not allowed – bug or feature?
I am using External Data to query MySQL database with passwordless read permission. I have noticed that supplying empty password in the configuration results in  being raised. However, I can get around by patching the ED_Utils.php (diff attached):

but that's not the way I would like to do it. I would like to know whether it's a bug or if there is any rationale behind asking non-empty password as open databases often provide passwordless access? Powermelon (talk) 10:56, 5 January 2015 (UTC)


 * Ah, good point; that was indeed a bug. I just checked in the change you suggested. Yaron Koren (talk) 17:14, 5 January 2015 (UTC)

#get_db_data: stored procedure
Hi Guys,

I am using #get_db_data a lot on my internal Wiki and wonder whether #get_db_data can call a stored procedure in a SQL database? If yes, what would be the syntax for that?

Many thanks, Reiner


 * I don't think that's possible, unfortunately. If you're using MySQL, you might be able to create a "view" instead, and query on that - it can be queried like a regular DB table. Yaron Koren (talk) 18:32, 29 January 2015 (UTC)

Cannot connect to sqlite database
Hey all, some assistance on troubleshooting this would be appreciated. No matter how simple of a query I try, the page comes back with a 'Cannot contact the database server' error. This is what we have in settings: include_once "$IP/extensions/ExternalData/ExternalData.php"; $edgDBServerType['gameDB'] = "sqlite"; $edgDBDirectory['gameDB'] = "/public_html/repopnation.com/wiki/extensions"; $edgDBName['gameDB'] = "repopdata"; Is there somewhere I can go for more detailed logs? I've been assured that the file exists in that directory (with .sqlite extension), and the appropriate r/w permissions are on it. What else is there to check? Thanks, Echelar (talk) 20:55, 2 February 2015 (UTC)


 * I don't know; I've never actually connected to SQLite. Maybe someone else can help. Yaron Koren (talk) 21:27, 2 February 2015 (UTC)

Undefined index: ... ED_ParserFunctions.php on line 494
I keep getting error messages like: And it seems this is a timing / race condition issue. If I create a template in which I define #get_db_data and #display_external_table calls like this: Then I can't submit this wikitemplate in one step. The order: works. So when editing this I need to comment out the call to the template again to avoid the probably buggy notice error message. Very strange and would be nice if this would be fixed. --WolfgangFahl (talk) 12:48, 4 February 2015 (UTC)
 * 1) define #get_db_data
 * 2) define #display_external_table
 * 3) then add example call in

 * Sorry, I don't know. What version of MediaWiki are you using, and what's on that line in that file? Yaron Koren (talk) 14:22, 12 February 2015 (UTC)


 * Thanks for your Reply Yaron Koren.

I am Using MediaWiki 1.24

for getting sql server am data adding

require_once "$IP/extensions/OdbcDatabase/OdbcDatabase.php"; include_once "$IP/extensions/ExternalData/ExternalData.php";

$edgDBServerType ['mydb'] = "odbc"; $edgDBServer     ['mydb'] = "my_dsn"; $edgDBName       ['mydb'] = "UNUSED"; $edgDBUser       ['mydb'] = "sa"; $edgDBPass       ['mydb'] = "sa@123"; $edgDBTablePrefix ['mydb'] = "dbo";

and i created my_dsn odbc in my windows wiki server in wiki page

now submit the page i got a below error message on top of the page

Undefined index: odbc in D:\xampp\htdocs\SNWiki\includes\db\Database.php on line 915

In Database.php the line 915 is below bold line

if ( class_exists( $class ) && is_subclass_of( $class, 'DatabaseBase' ) ) {

$params = array(

'host' => isset( $p['host'] ) ? $p['host'] : false,

'user' => isset( $p['user'] ) ? $p['user'] : false,

'password' => isset( $p['password'] ) ? $p['password'] : false,

'dbname' => isset( $p['dbname'] ) ? $p['dbname'] : false,

'flags' => isset( $p['flags'] ) ? $p['flags'] : 0,

'tablePrefix' => isset( $p['tablePrefix'] ) ? $p['tablePrefix'] : 'get from global',

schema' => isset( $p['schema'] ) ? $p['schema'] : $defaultSchemas[$dbType],'''

'foreign' => isset( $p['foreign'] ) ? $p['foreign'] : false

);

If i type wrong table name in wiki page it showing Below Errors

Notice: Undefined index: odbc in D:\xampp\htdocs\SNWiki\includes\db\Database.php on line 915

Warning: odbc_exec: SQL error: [Microsoft][SQL Server Native Client 10.0][SQL Server]Invalid object name 'Testtable1'., SQL state S0002 in SQLExecDirect in D:\xampp\htdocs\SNWiki\extensions\OdbcDatabase\OdbcDatabase.body.php on line 26

so i think connectivity is not a problem.

Kindly Help me

 * That's a lot of information! Well, my guess is that this is an issue with the OdbcDatabase extension - that it needs to be updated for use with MW 1.24. I would suggest contacting the author of that extension. Yaron Koren (talk) 14:09, 13 February 2015 (UTC)
