How to access Firebird database on localhost without knowing the appropriate user name and password

Submitted by admin on Sat, 11/16/2019 - 17:31
Assume you are a system administrator and you have forgotten your username or password so you have no longer access to your database. You don't have any other access to your database, you cannot reset the SYSDBA user's password because other people or applications are using it and you don't have access to them either but you really need access to certain records quickly. How annoying is that? Luckily, there is a solution for this problem but we also have to assume that we can shut down the database server for a short time.

Linux Bash: creating employee codes from basic personal details

Submitted by admin on Sat, 11/16/2019 - 17:25
Few years ago I wrote a simple bash script to generate employee codes for future project management systems. Now, that the time has come to create a system that must be able to generate employee codes automatically, I realized that it is more elegant to generate employee codes directly with PL/SQL functions so the script has become completely useless. I was going to delete it permanently from my filesystem, but then checked the code and decided to post it here because it is a simple but perfect example of how fast problems can be solved using Linux bash only. Experts can skip this post because probably it will show nothing new for them.
