how do i add another existing database

am i able to use dolphin with 2 databases or can i merge the 2 existing databases? I have a website using 7.1 and when i had to redo my site i had to create a new data base but there is important stuff i need on the other database and i need access to it one way or another...i tried to create a subdomain but i see it makes you create an new database so i didn't proceed...is there any way to access a database that is there but not in use, its extremely important that i get information from there

One, you can go ahead and create the sub-domain and set the site up and then import the database you need to access.  The other is to point the sub-domain to the old site if the files are still there and intact; just edit the inc/header_inc.php file to reflect the sub-domain.  Finally, you can also access the database using a GUI such as phpMyAdmin or the one from Oracle's website which is a free MySQL database tool.

You can import data from the old database to the new but it is not just a straight import as there might be existing rows conflicts.  You might want to hire someone that has good skills in MySQL and databases in general.

thanks!!!!!!!!! i created a subdomain now how do i import the database to the subdomain i just set up?

Did you just create the subdomain?  Or did you set up a new site under the subdomain?

If you have the old site still set up on the server and old database; you simply point the subdomain to the directory/folder of the old site.  Then you will edit the inc/header_inc.php and change the URL for the site.  The other paths will remain the same unless you moved the site into a new directory/folder.

In order to help you we need as much detailed information on your setup.
