Database trigger. A database trigger is procedural code that is automatically executed in response to certain events on a particular table or view in a database. The trigger is mostly used for maintaining the integrity of the information on the database.
Assisted Opening Knives. An assisted opening knife is a type of everyday carry knife that allows the user to open its blade with one hand by applying pressure to the thumb stud or the flipper. In the closed position, the blade is generally held in place by a torsion bar.
The knife that kicks the blade out by a cam-action is as much of a switchblade as anything in West Side Story, advertisements of âlegal switchbladesâ notwithstanding. There are âassisted openingâ knives which are partially opened like an ordinary lock blade, and then a spring fully opens the blade. As switchblades are called âautomaticâ knives, these can be called âsemi-automaticâ knives. Assisted opening knives do not appear to be treated as switchblades at this time.
