Thread:Project:Support desk/ 1050 - Table 'calendar' already exists/reply (5)

Use a tool like PHPMyAdmin. It has a graphical user interface and is really easy to use.

On the command line things become way more complicated (at least for unexperienced users like you):

You will have to log in, select the database and drop the table, e.g. with something like this:

mysql -u my-mysql-username -pmy-mysql-password

use my-database-name

DROP TABLE `calender`;

where you have to replace everything starting with "my-" with your actual names.
