Warning: mysql_query(): Your query requires a full tablescan (table xxxx_config, 242 rows affected). Use EXPLAIN to optimize your query. in /home/vmc/public_html/x/modules/protector/class/protector.php on line 44

**********************************************
Hello

What does "Use EXPLAIN to optimize your query" mean? Is that something I can add to some query to get better debug info?

I don't know if this is protector related but sure seams to be MySQL related. I went in to phpmyadmin to check the config table.
Table maintenance: Check table & Analyze table return no errors or tasks to do.

I don't seam to beable to turn protector off. I went in to modules and replaced the 1 with a 0 in the isactive field.

Do you know what t do?

Thanks

Here's how to use EXPLAIN: http://dev.mysql.com/doc/refman/4.1/en/explain.html

I don't know why you got the original error message. I've never seen that.

When I add EXPLAIN after SELECT the error becomes like this:
Warningmysql_query(): You have an error in your SQL syntaxCheck the manual that corresponds to your MySQL server version for the right syntax to use near 'EXPLAIN conf_name,conf_value FROM ty_config WHERE conf_title li in /home/vmc/public_html/x/modules/protector/class/protector.php on line 44

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/vmc/public_html/x/modules/protector/class/protector.php on line 45



When I run the QUERY in phpmyadmin I get no errors and it works fine.
SELECT *  FROM `ty_configWHERE `conf_titleLIKE '_MI_PROTECTOR%'

EXPLAIN goes before SELECT, not after it.

But you can't just add EXPLAIN to a query in XOOPS, since the query will output diagnostics, not the needed data from the database.

You would run the EXPLAIN query using phpMyAdmin, outside of XOOPS>

I also followed the blank screen instractions from the FAQ

I can login now at http://www.vmclinks.com/x/user.php

But when I go to the admin page I get
Quote:

This is your first time to enter the administration section. Press the button below to proceed."



Any ideas?

OK this is what I get

SQL query
EXPLAIN SELECT *

WHERE `conf_titleLIKE '_MI_PROTECTOR%'

I got in to the admin site like I said it shows me that green message that this is my first time in the admin area. Like on a new install.

When I clicked cancel it let me in to the admin area and I disabled the "Xoops Protector".
Now the site shows up in the user area.
Still have that Warning on top
Warningmysql_query(): Your query requires a full tablescan (table ty_config242 rows affected). Use EXPLAIN to optimize your queryin /home/vmc/public_html/x/modules/protector/class/protector.php on line 44


When I log out and back in I get that green "First time in admin area message"

Some thing is very wrong

OK

Disabled the protector and removed the two protector lines from mainfile.php.

Site is back up without protector now.

What do I need to do to get protector working again?

I don't know, but I saw that you posted the question at http://www.peak.ne.jp/xoops/md/xhnewbb/viewtopic.php?topic_id=1509
You'll probably get help there.
