	2	+-- Experimental table definitions for Microsoft SQL Server with
	3	+-- content-holding fields switched to explicit BINARY charset.
	4	+-- ------------------------------------------------------------

	6	+-- SQL to create the initial tables for the MediaWiki database.
	7	+-- This is read and executed by the install script; you should
	8	+-- not have to run it by itself unless doing a manual install.
	9	+
	10	+--
	11	+-- General notes:
	12	+--
	13	+-- The comments in this and other files are
	14	+-- replaced with the defined table prefix by the installer
	15	+-- and updater scripts. If you are installing or running
	16	+-- updates manually, you will need to manually insert the
	17	+-- table prefix if any when running these scripts.
	18	+--

	20	+
	21	+--
	22	+-- The user table contains basic account information,
	23	+-- authentication keys, etc.
	24	+--
	25	+-- Some multi-wiki sites may share a single central user table
	26	+-- between separate wikis using the $wgSharedDB setting.
	27	+--
	28	+-- Note that when a external authentication plugin is used,
	29	+-- user table entries still need to be created to store
	30	+-- preferences and to key tracking information in the other
	31	+-- tables.

Welcome onboard, Ryan! :)

Please don't forget to create your USERINFO file.

I asked about this on Bugzilla, but received no response: return 'SELECT page_id, page_namespace, page_title, ftindex.[RANK]' . "FROM $page,FREETEXTTABLE($searchindex , $match, LANGUAGE 'English') as ftindex " . 'WHERE page_id=ftindex.[KEY] '; You should'nt assume one particular content language.

#Comment by MaxSem (talk | contribs) 05:10, 7 August 2010

  public function numrows() {
	return $this->mRowCount;
  }

According to MediaWiki's conventions, it should be called numRows()

+			$dbw = wfGetDB( DB_MASTER );
+			if ( $dbw instanceof DatabaseMssql ) {
+				return '3000-01-31 00:00:00.000';

As I said in Bugzilla, you absolutely don't need to create a connection to master just to check database type.

#Comment by 😂 (talk | contribs) 23:30, 19 September 2010

numRows was fixed at some point, Block.php in r73348.

#Comment by Siebrand (talk | contribs) 12:28, 7 August 2010

Special:Search is broken on translatewiki.net (blank page) with:

PHP Notice:  Undefined property: SpecialSearch::$searchEngine in /www/w/includes/specials/SpecialSearch.php on line 796

#Comment by Reedy (talk | contribs) 17:39, 7 August 2010

As per r70629, please setup your autoprops. See Subversion/auto-props

#Comment by Nikerabbit (talk | contribs) 10:27, 8 August 2010

in tableName use $name[0]
in tableExists there is space after the function name. It also seems to miss a call to tableName()

#Comment by Platonides (talk | contribs) 15:08, 12 August 2010

I did a couple of changes in r70962 and r70963.

+ $wgDatabase->initial_setup( $conf->RootPW, $conf->DBtype );

You should instead pass as parameters $conf->DBname, $conf->DBuser and $conf->DBpassword which is what initial_setup() is using.

// FIXME: fields need to be properly escaped.

This must be fixed ASAP

#Comment by Reedy (talk | contribs) 08:05, 13 August 2010

if ( $ret === false ) { throw new DBQueryError( $this, $this->getErrors(), $this->lastErrno(), $sql, $fname ); }

$sql is undefined

#Comment by Reedy (talk | contribs) 20:48, 13 August 2010

		} elseif ( $ret != NULL ) {
			// remember number of rows affected
			$this->mAffectedRows = sqlsrv_rows_affected( $ret );
			return $ret;
		}

Does sqlsrv_rows_affected come from the library?

#Comment by MaxSem (talk | contribs) 06:43, 21 August 2010

The changes to Block.php probably miss some manual comparisons with 'infinity'.

#Comment by MaxSem (talk | contribs) 07:20, 21 August 2010

Another concer: I don't think that view counters work on MSSQL. This needs a verification, see Article::incViewCount().

#Comment by OverlordQ (talk | contribs) 20:01, 11 November 2010

+ 'rc_id' => ( $dbw->nextSequenceValue( 'rc_rc_id_seq' ) > 0 ) ? $dbw->nextSequenceValue( 'rc_rc_id_seq' ) : 0,

That breaks in hilarious ways.

INSERT INTO recentchanges rc_id,... SELECT 12345,... doesn't do what you want and breaks the unique constraints.

#Comment by 😂 (talk | contribs) 13:32, 5 January 2011

Also the nested ternary is hard to read.

#Comment by 😂 (talk | contribs) 00:44, 8 February 2011

Setting this to resolved. All the breakages to non-MSSQL specific code have since been fixed.

MSSQL support is incomplete, but it's not a blocker to deployment or release.

#Comment by MaxSem (talk | contribs) 02:38, 8 February 2011

Why should it be a problem? Just tag with nodeploy.
