I would like to make an sql query to compare two tables with identical columns, both names and types. Each table has a unique key. I want the query to return any rows that contain unequal values. I know could do something like this select * from table_1, table_2 where table_1.key = table_2.key and ( table_1.col1 != table_2.col1 OR t...
Hi! I'm trying to figure out if there is an easy way to count the number of words that appear in small paragraph (#1) and small paragraph (#2). Generally, Im determining how much overlap there is in these paragraphs on a word by word basis. So if (#1) contains the word "happy" and (#2) contains the word "happy" that would be like a +1...
Hi, Lift/Scala is getting a lot of attention lately. Having worked with Grails in the past (and finding it quite handy BTW), I'd like to know if there's anyone who has tried both and what's his/her opinion about them. Is one of them better suited for one kind of scenarios whereas the other is better for other kind, or they compete should...

Okay, so I'm getting my MySQL Version like so: preg_replace('#[^0-9\.]#', '', mysql_get_server_info()); Which gives me a number like: 5.1.36 That's all good. What I need to do, is compare that version with another version. I was about to attempt to write my function to compare them, when I thought of version_compare(). However, upon ...
I have two arrays that both hold 5 sets of random numbers. First I display a list of all the numbers in the first array; then I need to add to that list, any number that's not in the first array, and display each of those. To do that, I use another array to put the unique values in to display. I already have a function that displays the...
I got data measurements from image. I mean profile scan data. (image intensity values that are taken along one line) And what I want is to get data from another image's line and compare them together. I want to know if they are similar or not. For example I got: int data1[N]; int data2[N]; And I want to compare them. If they are not...

I have a litte problem and was wondering how to solve it. I have a generic class Tuple<A,B> and now I would like to sort their tuples according to A and B. It should look like this: Unsorted: (1,5) (2,8) (6,8) (1,4) (2,4) Sorted: (1,4) (1,5) (2,4) (2,8) (6,8) For that reason I thought of implementing a generic compare method (pu...
Hi all, I have the following 2 data.frames: a1 <- data.frame(a = 1:5, b=letters[1:5]) a2 <- data.frame(a = 1:3, b=letters[1:3]) I want to find the row a1 has that a2 doesn't. Is there a built in function for this type of operation? (p.s: I did write a solution for it, I am simply curious if someone already made a more crafted code)...
Hello. If I declared a bool isTrue = false; // init it to false and I can get the value from a string strVal = T; // I assumed it is the TRUE value I heard it is not a good code style to compare string in C# like if (isTrue.tostring() == strVal) {}. Some time, I covert the the string variable to enum then I can compare it more conv...

I need to compare only the rows that got column X equal with the ID of 3, not to compar...
Hi all, I'm trying to do a function that will check the php date against what is in the database. If the current date (YYYY-MM-DD HH:MM:SS) is 24 hours after the stored database date, then it will continue, otherwise it won't do anything.. If that makes sense? Here's how I'm trying to get it to work, but not 100% sure how: $now = date...

I'm trying to determine which header declares a specific function. I've used grep to find instances of the function's use; now, I want to find which header is included by all the files. I'm aware of the comm utility; however, it can only compare two sorted files. Is there a Unix utility that can find the common lines between an arbitrary...
