I have a classic 3-tier web application build with MySQL and Tomcat.
I want to save the creator id of each database record for all tables at creator_id column or just log it somewhere.
Current user is stored at the http session object.
Modify all queries and pass creator id parameter is unacceptable.
Can I solve the problem using triggers, alter table commands etc.?
What is the best way to do that?
PS. Hacks are acceptable and welcome.
The database can’t possibly know which site user is sending the query, all it knows is which database user. And if it’s a web application, it’s probably the same database user all the time, no matter who is logged in on the website.
The short answer is that no, you’re going to have to go with your “unacceptable” option, unless you want to create a database user for every site user, and have the site open the database connection using those, instead of one “shared” user. But that may end up causing more problems than it solves.
