What is the best log file format?
Guys: Forgive me to raise such an issue again. We are developing a database tool, we'd like to write a log file in such format which is extendable and easy to be imported into a database table. We all feel filter these info by using SQL is a good idea, since the log will be a long file and "search" may not good enough. Could you give me some suggestions? Any experiences will be useful too! Thanks in advance.
