  • How do I remove database name from SQL Server generated script?

    - by bucha
    Anytime I use 'script table as' - 'Insert To' (or other command), the script generated automatically places the database name in the script. Such as: INSERT INTO [DatabaseName].[dbo].[tblToBeInserted] ... While not a huge problem to just delete it, it has slipped by a few times and the script breaks if run on a different server with a different database name but has the same schema. (Such as running on [DatabaseName.Test]) Is there an option I can change, or can I modify the output in any way to remove this?

  • Perl Term::ReadKey don't wait for newline

    - by tim
    In a perl script, I'm trying to accept input without blocking and without echoing the characters entered (The script is producing output and I want to have 'hotkeys' to alter its behaviour). I got as far as using use Term::ReadKey; ReadMode( "cbreak", STDIN ); if($input = ReadKey($pause_time, STDIN)){ #process input } But once the user types anything then the script stops until a newline is entered. I'd like the input to be processed per-character, without waiting for a newline.

  • Automating R Script

    - by ETD
    I have written an R script that pulls some data from a database, performs several operations on it and post the output to a new database. I would like this script to run every day at a specific time but I can not find any way to do this effectively. Can anyone recommend a resource I could look at to solve this issue? I am running this script on a Windows machine.

  • Is it possible to have variable find conditions for both the key and value?

    - by DarrenD
    I'm trying to pass in both the field and the value in a find call: @employee = Employee.find(:all, :conditions => [ '? = ?', params[:key], params[:value].to_i) The output is SELECT * FROM `employees` WHERE ('is_manager' = 1) Which returns no results, however when I try this directly in mysqsl using the same call without the '' around is_manager, it works fine. How do I convert my params[:key] value to a symbol so that the resulting SQL call looks like: SELECT * FROM `employees` WHERE (is_manager = 1) Thanks, D

  • closure not working

    - by dorelal
    var Dog = function() { var _instance = 'hello world'; return function() { console.log(this._instance); } } (); //note that it is self invoking function var l = new Dog(); //#> undefined In the above case I was expecting output of 'hello world'. Why this._instance is not accessing the the varible which should be accessible by virtue of closure. I tested this in FF and am getting undefined.

  • when to use const char *

    - by djones2010
    If i have a function api that expects a 14 digit input and returns a 6 digit output. I basically define the input as a const char *. would that be the correct and safe thing to do? also why would I not want to just do char * which I could but it seems more prudent to use const char * in that case especially since its an api that i am providing. so for different input values I generate 6 digit codes.

    - by gsp
    I have a large data file that is creatd from a shell script. Next script processes it by sorting and reading several times, that takes more than 14 hours, it is not viable.

  • Tracking image views - PHP

    - by RS7
    I'd like for my app to be able to tell if an image hasn't been viewed in the last 30 days and remove it (along with data in the DB associated with it). I know you can have PHP read and output the image dynamically but I've heard its quite taxing on the system. Is there a way to for me to track these hits even when the image is viewed directly? (would htaccess be able to do this?) Thanks in advance.

  • HTML/CSS Design for Report

    - by Kevin Brown
    I'm looking for some resources that demonstrate good graphic design for generated (PHP/HTML/CSS) reports. The website I'm designing is essentially a long test. Everything is finished except the report generation, and this part needs to look good! I'd appreciate any advice/resources you can point me to! I know this isn't directly programming related, but my purposes do encompass coding and output.

  • Iterating over key/value pairs in a dict sorted by keys

    - by Helper Method
    I have the following code, which just print the key/value pairs in a dict (the pairs are sorted by keys): for word, count in sorted(count_words(filename).items()): print word, count However, calling iteritems() instead of items() produces the same output for word, count in sorted(count_words(filename).iteritems()): print word, count Now, which one should I choose in this situation? I consulted the Python tutorial but it doesn't really answer my question.

What could be the problem?
