• SQL - Add up all row-values of one column in a singletable

  - by ThE_-_BliZZarD

  Hello Everybody, I've got a question regarding a SQL-select-query: The table contains several columns, one of which is an Integer-column called "size" - the task I'm trying to perform is query the table for the sum of all rows (their values), or to be more exact get a artifical column in my ResultSet called "overallSize" which contains the sum of all "size"-values in the table. Preferable it would be possible to use a WHERE-clause to add only certain values ("WHERE bla = 5" or something similar). The DB-engine is HSQLDB (HyperSQL), which is compliant to SQL2008. Thank you in advance :)

• Given a PHP class would be the best and simplest way to override one or two of its methods with one

  - by racl101

  Here's the objective. I have a PHP class and there are one or two of its methods that I would like to override with my own. As I understand OOP (in PHP and in general) I could write a child class that extends it and overrides the functionality of the methods in question. However, I was wondering if this is the best way of achieving this task and if this is a proper use for child classes or if there is something better in PHP for what I'm trying to do.

  - by Eli

  Hi all, In considering several possible solutions to a recent task, I found myself considering how to get a php file that includes it's own MD5 hash. I ended up doing something else, but the question stayed with me. Something along the lines of: <?php echo("Hello, my MD5 is [MD5 OF THIS FILE HERE]"); ?> Whatever placeholder you have in the file, the second you take its MD5 and insert it, you've changed it.
