Apache2 httpd app server for SQL [closed]

I’m trying to figure out how to build an App server for a SQL Database using Apache2 or httpd.

I’m familiar with how to set this up using other software, such as NodeJS. I’m more interested in using Apache/httpd, if possible.

There’s a mod_dbd but the documentation is lacking in detail or example: https://httpd.apache.org/docs/current/mod/mod_dbd.html

Is this the only module I would need to configure an app server for interfacing with a SQL Database? I’m unclear with what to write in the config file, using mod_dbd, to request something from a database.

Any help would be greatly appreciated.
