Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I get this occasionally as well - your query likely has an error in it. I'd run the query directly against your database (mysql workbench/phpmyadmin/mysql console/etc) to find out where the error is.
On a more general / security-oriented note: You know how every now and then you hear of those huge data breaches? Well a lot of the time that's a result of SQL injection, caused by developers putting variables directly into the query, which allows attackers to modify the SQL (in various creative ways).
The easiest way to avoid that vulnerability is to always use parameterised queries (even when it might not be strictly necessary), and - in a situation when you're looping through repeating the same query with different data - it also has the advantage of being more efficient.
