If you aren't observing any issues with your application and your application is open to the internet, it is not unlikely that those errors are being caused my someone on the outside attempting SQL-injection against your site (and apparently failing). If it is feasible, check your apache access.log for the same timestamp as you error log shows and see if shows some unusual requests. If your application security is tight, these attacks are moderately harmless. While you can harden your app against such intrusion, there is no way to prevent the attempts. You may well be worried about nothing..
