Tracked in Phabricator
Task T157651

sql.php is a maintenance file which allows performing SQL queries. If you give an SQL file as the first argument, it will replace MediaWiki specific code comments like /*_*/ for the configured database prefix (among others). If you don't give it a file, then you can query the database in an interactive fashion, similar to the MySQL command line tool.

This script is often used if you want to upgrade MediaWiki, but have a large, master/replica-database setup and don't want any downtime. Instead of using update.php, you might use sql.php to apply database individual patches from maintenance/archives directory on each sql server separately, taking the individual server out of rotation while the schema change runs. Generally you should only do this if you have to - most users should use the update.php script instead.
