    - by ddan
    I have a MySQL query that: gets data from three tables linked by unique id's. counts the number of games played in each category, from each user and counts the number of games each user has played that fall under the "fps" category It seems to me that this code could be a lot smaller. How would I go about making this query smaller. http://sqlfiddle.com/#!2/6d211/1 Any help is appreciated even if you just give me links to check out.

  • Regular expression - starting and ending with a letter, accepting only letters, numbers and _

    - by jreid9001
    I'm trying to write a regular expression which specifies that text should start with a letter, every character should be a letter, number or underscore, there should not be 2 underscores in a row and it should end with a letter or number. At the moment, the only thing I have is ^[a-zA-Z]\w[a-zA-Z1-9_] but this doesn't seem to work properly since it only ever matches 3 characters, and allows repeated underscores. I also don't know how to specify requirements for the last character.

  • Weird jQuery UI Slider behavior using Page Up/Down

    - by qlassic
    I'm using jQuery UI's slider to update a div containing a number. Dragging or using the left/right keys should only allow the user to choose a number between 1 and 5 (this works as intended). However, if the handle has focus and I use page up/down, I start to get rounded values that are well out of the range of 1-5. Anybody experience the same? Thoughts?

  • Without width printing format in C

    - by yCalleecharan
    Hi, in C if I have a printf statement containing say "%.2f", it says that the precision is 2 digits after the decimal place. I haven't explicitly specify the width. I have two questions: Is this good programming practice?; Is without specifying the width means that the width of the field will get adjusted automatically when printing the number, irrespective of the number of digits it contains? Thanks a lot...

  • Loop through array, print with string.

    - by Adam
    I have a simple array like: var myArr=["one","two","three"]; an I have a counting loop, which increases the value of var i by one. What I want to do is print the next value from the array each time the loop runs, next to a text string, like so: alert('value number '+myArr[i]+); But for some reason I can't get this to work. The following code works, so I'm assuming I'm not calling the counter right: alert('value number '+myArr[0]+);
