Atenção:

Since MediaWiki 1.28, sql.php may have some side effects. Please make sure you have run update.php and things do not break before running this script! Rastreado no Phabricator Tarefa T157651

sql.php é um arquivo de manutenção que executa consultas SQL de um arquivo específico para o banco de dados. 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.
