Manual:$wgDBprefix/hi

विवरण
तालिका का नाम उपसर्ग। यह अल्फ़ान्यूमेरिक होना चाहिए, न तो रिक्त स्थान और न ही हाइफ़न, और "_" में समाप्त होना चाहिए। If you only have access to a single database and wish to install more than one version of MediaWiki, or have other applications that also use the database, you can give the table names a unique prefix to stop any naming conflicts or confusion.

For example, if you use the prefix 'wiki_' then the table 'page' will be named 'wiki_page' instead.

You need to set this at the time of initial configuration, or manually change the table names at a later date. Changing this setting does not automatically update the names of the tables in your database.

Common value
Many installers set the database table prefix " " to " " by default.
