The syntax to create links in SQL reports is cumbersome.  
The below link, as example, often gets typos and then fails to work when run.

CONCAT('<a href=\"/cgi-bin/koha/cataloguing/addbiblio.pl?' , 'biblionumber=' , biblionumber , '\">' , biblionumber , '</a>'), AS 'biblionumber',

Koha needs a way to allow the user to enter a 'shorthand' or alias in the sql query that is then replaced by the URL.
For example:
SELECT biblionumber|link_detail from biblio 

would resolve to 

SELECT CONCAT('<a href=\"/cgi-bin/koha/cataloguing/addbiblio.pl?' , 'biblionumber=' , biblionumber , '\">' , biblionumber , '</a>'), AS 'biblionumber' from biblio
