Possible to get a TXT_STRING in database and echo language file?

[magnus_sylvania]

I have a extra filed in the database(eg. extrafiled_sample) where I want to add a text string like: TEXT_SAMPLE

 

I want to ECHO the value like <?php echo $extrafield_sample;?> no problem - gets TEXT_SAMPLE on the screen.

But I want to get TEXT_SAMPLE from the language file.

In the language file I have define('TEXT_SAMPLE','This is a sample text');'

 

So I want the result echo = This is a sample text.

It seems to me, if you are defining the text string in the language files anyway, why not simply <?php echo TEXT_SAMPLE; ?>

using the database entry just seems like an extra step that isn't required, or maybe I'm not getting it?
