Admin deleted causing erros database

[Manoel J?nior]

Deleted my administrator user, which I had done numerous posts on forum, unfortunately I was careful to protect myself in config.php and put my user as undeletableusers.

I created a new user with the same name I had, I went into my database and modified my group to be an administrator, right now I'm checking the logs to see which admin gave me this tragedy.

I would like you to help us, because whatever topic I go, where I had commented or even started posting gives SQL error as below:

Invalid SQL:
SELECT * FROM `thread` WHERE `postuserid`=;

MySQL 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 '' at line 1

I've tried to change my userid in the database to my old, who was the userid 1, but still did not work.

Could someone give me a hand as I could fix this error?

PS. Sorry my bad english.
