I'm very interested in using Mahara but still a newbie at MySQL. I'm running a WAMP on my XP laptop to develop/test. When installing the core, I get the following error:

mysql 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 'group' at line 1] in adodb_throw(SHOW INDEX FROM group, )

Call stack (most recent first):

My WAMP consists of Windows XP, MySQL 5.1.30, PHP 5.2.7, Apache 2.2.10.

Thanks for any help you can give.

Hi Bruce - it looks like you found a bug in ADODB. I think I have a fix for it, I would be grateful if you could try it out and let me know if it helps you.

In the file lib/adodb/drivers/adodb-mysql.inc.php, line 92 is:

     $rs = $this->Execute(sprintf('SHOW INDEX FROM %s',$table));

Could you please change this line to (note the added quote marks):

     $rs = $this->Execute(sprintf('SHOW INDEX FROM "%s"',$table));

And let me know if that makes it work? Drop and re-create your database before re-attempting the installation.

I dropped the database and re-created it, edited the file as shown, and re-installed. This time, I'm not getting an error but it is hanging while still installing the core (a screenshot posted here: http://www.drellis.net/mahara_install_hang.png) Jumping over into phpmyadmin I can see that 57 tables have been created. After giving it about 20 minutes, it still is on the first item (core). Stopped the process, dropped/recreated the table, and tried it again to get the same issue. I'm not getting the original error (that's good) but it is now hanging.

 Any ideas?

Hi Bruce,

What is the last table that gets created before it hangs (you should be able to see this in phpmyadmin)

Cheers,

Penny

I removed mahara and re-installed it and check the error log. No errors reported though the install is still happily spinning. No errors in the php_error.log either. It now has 60 tables in the database (usr_registration was the last before re-installing mahara...now it is view_layout).

 Any ideas?

08 January 2009, 21:03

Hm, the next table after that one is 'view', I wonder if this has caused another issue between MySQL and ADODB... but it's really hard to tell without any error messages to help with .

Have you found and checked all of the error logs you can find? Does someone else on the forums with WAMP experience have an idea about this issue, or where errors might be logged to?

09 January 2009, 2:45

Hmmm... if the last table is different each time it could be that php is running out of resource (time or memory).

Do you have access to your php.ini?  Can you make sure log_errors is on?

 Hi

I think I am getting the same error - it hangs when installing the core component.

I have made some progress. By adding the session.save_path (3;c:\wamp\data\sessions) to php.ini I have reduced the errors to the following the first time I try to launch Mahara

If I stop the installation and try to run it again I get more errors, some of which are because tables have already been created.

I have only a limited knowledge of PHP and therefore am a bit in the dark. I notice that the number of tables created varies. Last time I had 53, but I have had as low as 35

Is this of any help?
