Debugger for MySQL: Breakpoints
Breakpoints are an efficient method of streamlining and accelerating the debugging process. To stop the execution of your code on a specific line, place a breakpoint on it by clicking the gutter area on the left. Each breakpoint can have its own activation conditions – one or several Boolean expressions - that should be met during code execution for the process to be brought to a halt. Debugger for MySQL provides everything necessary to quickly set and edit breakpoints and efficiently control the execution of your stored MySQL procedures or functions.

"...Aptly named “Debugger for MySQL”, I found this inexpensive tool to be quite easy to get the hang of, since it looks and behaves like most programming debugging environments."
"...Debugger for MySQL is a prime example of a tool that does one thing and does it well."
