If it is not working, go back to the hard drive. An SQLite trigger is a named database object that is executed automatically when an INSERT, UPDATE or DELETE statement is issued against the associated table. SQLite is the most used database engine in the world. If you aren't sure, try loading everything into memory and see if you have problems on your server during periods of heavy load. Summary: this tutorial discusses SQLite trigger, which is a database object fired automatically when the data in a table is changed. What Is SQLite SQLite is a C-language library that implements a small, fast, self-contained, high-reliability, full-featured, SQL database engine. To create a new database using DB Browser, simply click New Database to create a database for your data. Your choice should be based on the needs and specs of the system you are operating on. However, we will show you both ways in which to do this. You will have better real world performance under very high loads (assuming you can accomodate the memory usage), but a much higher memory footprint. On the other hand, if you keep everything loaded into memory, it will have a much higher memory footprint, compensated by a much faster database access time. The downside to this is slower access times, translating to decreased real world performance under very heavy loads. As I tried it the first time, I was a bit annoyed for the extra step to run the generated SELECT script. It runs on Windows, Mac and Linux with a more polished user interface and a higher update frequency. If you keep everything on the file system, this will save memory because you don't have to have everything loaded (into memory) at once, and even when something is loaded it quickly closes. SQLiteStudio is very similar to DB Browser for SQLite. Basically, if you keep it on the local file system and load it into memory on demand, this will always have a lower (or equal) memory footprint than if you have ALL data loaded into memory at all times.
