Okay¬Ö Let's continue.

Your arguments are valid. You also gave me some ideas about SQL::Abstract.

My idea was that I have a few levels where the data is handled. When the need arises to add a column, I need not change the code which retrieves the data from the database, because it will, thanks to the * give me all columns. And this might not be just one function, but several.

I only need to change those functions, which have to handle the new column.


s$$([},&%#}/&/]+}%&{})*;#$&&s&&$^X.($'^"%]=\&(|?*{%
+.+=%;.#_}\&"^"-+%*).}%:##%}={~=~:.")&e&&s""`$''`"e

    Sure, though I think you'd still have a problem if a column gets renamed? But don't get me wrong, I'm not fixated on this argument against SELECT * - you know your database better than I do, so it may be possible for you to say now that columns will never get renamed and adding columns will be rare, even in the future. I just have been enjoying writing code using SQL::Abstract via Mojo::Pg, and I see several advantages over hard-coded SQL (there are of course disadvantages too, like slightly more verbose code in certain cases, and I assume the performance is not as good when compared to hard-coded SQL). I do still have a few hard-coded SQL statements in my codebase too.
