How to change wp_ database prefix


According to a study, more than 80% of wordpress webmasters don’t change default database prefix. By default wordpress database prefix is set to wp_ which means that every table in the database is going to have wp_ in its start. This is not a good practice. Leaving this unchanged will definitely result in some serious security issues in future.

This makes easy for hackers out there to assume that you have left the wordpress table prefix unchanged and execute a sql injection attack for wp_ prefix.

Changing wordpress database prefix from sql commands can become a little tricky if you have a lot of plugins installed.
