How the Debugger Works
To have visibility into the internal workings of a stored routine, the debugger prepares a special version
of the procedure, function, or trigger being debugged, instrumented with extra code to keep track of the
current line being stepped into and the values of all the local variables. Any other stored procedures,
functions, or triggers called from the routine being debugged are instrumented the same way. The
debug versions of the routines are prepared for you automatically, and when the debug session ends
(by either pressing F5 or Shift+F5), the original versions of the routines are automatically restored.
