数据库麻烦和php麻烦

Question

I am having trouble with my create a table .php script, It creates all tables in the database except one which is 'useroptions'. I am new to php but still understand it to an extent, feedback and help would be greatly appreciated.

 <?php
include_once("php_includes/db_connect.php");

$tbl_users = "CREATE TABLE IF NOT EXISTS users (
              id INT(11) NOT NULL AUTO_INCREMENT,

Also I'm getting this error when I click on database ?

Error SQL query:

SELECT tracking_active
FROM  `phpmyadmin`.`pma_tracking` 
WHERE db_name =  'circle'
AND table_name =  'blockedusers'
ORDER BY version DESC

MySQL said:

1146 - Table 'phpmyadmin.pma_tracking' doesn't exist

Answer 1

Your useroptions create table statement has an invalid unique key ref: UNIQUE KEY email (email). There is no column email on useroptions. Remove it and it will likely run clean.

As for the query issue, not really sure what you're trying to do.
