I have a problem where I want to tweak a simple select in an
"unobtrusive way". Imagine I have the following select statement:
"SELECT name FROM customer LIMIT 1" and I get a normal result set from
this. But, could I,maybe by defining some other function or similar,
change the result set *without* changing the query? Suppose I get the
result from the query above, saying: "Peter Peterson". I would
(sometimes) like to get the result "<div>Peter Peterson</div>" but I
should not have to change the original query.
I know I could write "SELECT '<div>' || name || '</div>' as name FROM
customer" but then I have altered the original query and I cannot do
this since it is supposed to function different in two different
situations.
Any ideas on how to achieve this? I would like to let the original sql
code stay original. I can prepare postgres before executing the sql if
this makes it easier to acheive the goal
