The former installation should not be contributing to this problem (the DB tables changed completely). Which version of SMW are you using now?

Closing this bug as WORKSFORME since the described failure could not be reproduced, and since no further information is provided on the problem.

This error also happens for me when using MW 1.14.0, PHP 5.1.6, and MySQL 4.0.18-MAX

The issue is that the code in SMW_SQLHelpers.php, SMW_SQLStore2_Queries.php and SMW_SQLStore2.php generates SQL which defines tables as "KEY AUTO_INCREMENT", but this needs to be "PRIMARY KEY AUTO_INCREMENT" for the version of MySQL in use.

I have patched my install with these changes, and both the Admin page interface and running the SMW_setup.php directly now works.

When running SMW_setup.php:

Selected storage engine is "SMWSQLStore2" (or an extension thereof)

Checking table xxxxx_smw_ids ...

Table not found, now creating...

A database query syntax error has occurred.
The last attempted database query was:
"CREATE TABLE xxxxx.xxxxx_smw_ids (smw_id INT(8) UNSIGNED NOT NULL KEY AUTO_INCREMENT,smw_namespace INT(11) NOT NULL,smw_title VARBINARY(255) NOT NULL,smw_iw VARCHAR(32) binary NOT NULL,smw_subobject VARCHAR(32) binary NOT NULL,smw_sortkey VARBINARY(255) NOT NULL) ENGINE=InnoDB"
from within function "SMWSQLHelpers::createTable".

Database returned error "1064: You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near 'KEY AUTO_INCREMENT,smw_namespace INT(11) NOT NULL,smw_title V (xxxxx.xxxxx.xxx)"

Paul's fix above worked for me as well, but only includes/storage/SMW_SQLHelpers.php and includes/storage/SMW_SQLStorage2.php needed the tweak (s/(?<!PRIMARY) KEY AUTO/).

Ah, for shame. s/(?<!PRIMARY) KEY AUTO/PRIMARY KEY AUTO/

Probably similar error with "AUTO_INCREMENT" (wikimedia 1.17) in Drafts extension (http://www.mediawiki.org/wiki/Extension_talk:Drafts). Update script raport an error:

for proper Draft.sql content:

Isn't there something wrong with wikimedia update.php which cause undescore removement from valid sql syntax?

This bug hasn't seen any update during the last year and it is unknown if this bug still relates the current SMW 1.8/SQLStore3.

Please feel free to reopen this bug again if it applies to SMW 1.8.
