Any ideas why I am suddenly getting this error in the db?

<pre>warning: Missing argument 2 for variable_get() in /home/apockot/ public_html/includes/bootstrap.inc on line 152.</pre><pre>user error: 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 '1 AND uid != 0' at line 1 query: SELECT * FROM user WHERE uid IN 1 AND uid != 0 in /home/ apockot/public_html/includes/database.mysql.inc on line 66.</pre>
