    - by kokkch
    Possible Duplicate: How to get the Nth digit of an integer with bit-wise operations? I spent more than one day trying to solve this problem but I couldn't find a solution.

How can I do this? Can anyone help?

  • How effecient is a details table?

    - by Jeffrey Lott
    At my job, we have pseudo-standard of creating one table to hold the "standard" information for an entity, and a second table, named like 'TableNameDetails', which holds optional data elements. On average, for every row in the main table will have about 8-10 detail rows in it. My question is: What kind of performance impacts does this have over adding these details as additional nullable columns on the main table?

  • Is there a way to organize a icon collection to allow for easy searching?

    - by John M
    Is there any way of organizing a icon collection so that it easier to find needed icons? For example: the program needs a save icon there are 5 icons collections on your HD that have a save icon and there are 5 more collections that don't have a save icon (but you don't know that) do you browse through each icon collection? run a search (assumes files are named consistently)? Would it be ideal to have some sort of organized directory (printable?)?

  • MySQL: Digits (1.75) to Friendly Time (1 hour and 45 minutes)

    - by Nick
    In my MySQL database, I have a float field named "HoursSpent" with values like "0.25", "1.75", "2.5", etc. Is there a way that I can have my SELECT statement format those values in a friendly format like this?: 0.25 = 15 minutes 1.75 = 1 hour and 45 minutes 2.5 = 2 hours and 30 minutes The "HoursSpent" field is supposed to only have values in 0.25 increments, but if somebody were to put something random like 0.16, it would be nice if the SELECT statement handled that by rounding it up to the nearest 0.25 (so in this case 0.16 would become 0.25, or 15 minutes).

  • Javascript Function Definitions

    - by Pierreten
    I was wondering why the Vector variable defined within this self executing javascript function doesn't require a var before it? Is this just some other type of syntax for creating a named function? Does this make it so we can't pass Vector as an argument to other functions? (function() { Vector = function(x, y) { this.x = x; this.y = y; return this; }; //...snip })()

  • Fetching Cassandra row keys

    - by knorv
    Assume a Cassandra datastore with 20 rows, with row keys named "r1" .. "r20". Questions: How do I fetch the row keys of the first ten rows (r1 to r10)? How do I fetch the row keys of the next ten rows (r11 to r20)? I'm looking for the Cassandra analogy to: SELECT row_key FROM table LIMIT 0, 10; SELECT row_key FROM table LIMIT 10, 10;
