In the repeaters, one of the column is text and it should be linked to url ,i.e the url coming from database.There are other options to link like page,anchor,document,email…etc.There is no option that the text can be linked with database url.
If your field type is setup as URL then you should be able to link that field to a repeater.
There are always these ways around if you are still stuck.

You can also do it through code.

Although you would need to add both the link and the target values so that your code knows to open your link in a new tab or in the same window.
