I was struck by an insight the other day: instead of using special buttons in my db management tool for inserting, deleting and updating, I could use the dbNavigator component. This is a component which I never use as it seems to be most effective when directly editing grids, an activity which I never program. So the component was far from my mind, but exactly what I needed for this tool. I didn't even have to program the navigator's buttons - they 'knew' exactly what to do. I define which buttons are active depending on whether the query is live or not.
It also turned out that there was a problem with the tokeniser in the parse routine: I hadn't really checked any semi-complex queries. This wasn't too difficult to fix but was rather annoying.
