  • Can IF be used to start a MySQL query?

    - by Littledot
    Hi there, I have a query that looks like this: mysql_query("IF EXISTS(SELECT * FROM predict WHERE uid=$i AND bid=$j) THEN UPDATE predict SET predict_tfidf=$predict_tfidf WHERE uid=$i AND bid=$j ELSE INSERT INTO predict (uid, bid, predict_tfidf) VALUES('$i','$j','$predict_tfidf') END IF")or die(mysql_error()); But it dies and mysql tells me to check the syntax near IF EXISTS(....) Can we not use an IF statement to start a mysql query? Thank you in advance.

I work with GCC 4.4.2 and create a preprocessed file with -E but do not want such structures in it.

  • C/C++ definitions of functions

    - by Vit
    Yesterday, I have been watching discussion here, about compilers and linkers. It was about C library function definitions. I have never thought of that, so it inspired me to do some searching, but I cannot find exactly what I want. I wonder, what is the smallest syntax you need to add into your source code to enable just printf() function. I mean the function declaration from stdio.h you need.

    When our server comes up we need to check a file to see how the server is configured. We want to search for the following string inside our /etc/aws/hosts.conf file: MYSQL_ROLE=master Then, we want to test whether that string exists and use an if/else statement to run one of two options depending on whether the string exists or not.

  • PHP: Check if it has been one week since timestamp

    - by Rudi
    Hi guys, Let's assume: $time = '2010-05-17 02:49:30' // (retrieved from MySQL TIMESTAMP field) How do I do the following in PHP: 1) Check if it has been more than one week since this time has passed? 2) Assuming "false" on (1), find out how much more time until the one week mark, rounded to days and hours remaining. I know this is pretty straightforward, but it uses a very specific syntax. Having never played with time calculations before, I'd appreciate some guidance. Thanks!

  • In Java, is there a way to write a string literal without having to escape quotes?

    - by Matthew
    Say you have a String literal with a lot of quotation marks inside it. You could escape them all, but it's a pain, and difficult to read. In some languages, you can just do this: foo = '"Hello, World"'; In Java, however, '' is used for chars, so you can't use it for Strings this way. Some languages have syntax to work around this. For example, in python, you can do this: """A pretty "convenient" string""" Does Java have anything similar?

  • Where does code within Script tags go in the resulting AS class?

    - by Hanno Fietz
    I was wondering what happens to the code contained in an <mx:Script> tag. If I define a function tehre, it just becomes a member function of the generated class. But I noticed that it seems OK for the compiler if I just write some (static) method calls there (specifically, I call Font.registerFont()). I feel kind of guilty for doing this, because I have no idea what's really happening and when the code gets executed.

    This may be a completely dumb question, but I've seen a couple examples declaring the variables AFTER putting them in bind_param: http://devzone.zend.com/article/686 I've never seen this done before and all my programming knowledge says I should define them before hand.
