Does anyone understand this error in SQL syntax

Can anyone help me to understand what the below means - keep getting this error and can't figure out how to fix it

2017-01-07 19:04:44 - PHP Notice: 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 'A=0'' at line 1<br />Error No: 1064<br />SELECT * FROM url_alias WHERE `query` = 'route=0' OR `query` = 'product/product'A=0' in /www/sites/52c/8c8/shop.angeldancewear.co.uk/web/system/library/db/mysqli.php on line 41

All help appreaciated

Remove the apostrophe before A=0

Thanks @sculptex for the advice - but there is no such entry in my sql.

Is this an SQL injection attack? - and if so, what can be done to stop them?
Thanks

Looks like this is doing the rounds

I blocked an IP from Aberdeen (Tiscali) today who was also trying that A=0 nonsense

Didn't get any errors in latest version of OC though.

How did you identify the IP address in order to block it??

It was in the Customers Online Report list (accessible from the dashboard)
