If you need to add, access or remove any tables, queries or data from the database that your website features run off i.e. blog or forum, you will need to administer your database.
You can administer your MSSQL database directly from your 123-reg Hosting control panel. To do so you will need to do the following:
Scroll down to the Web hosting section.
Select the relevant domain name from the drop down box and click on the Manage button.
Click on the MSSQL Database link in the Web Tools section of your hosting control panel.
In the Manage Databases section press the Manage button to access your database administration area.
