sql - Is it better in MySQL to have 1 large table or 2 smaller tables? -

-

This is my position: I have around 50 different data that I need to store for 1 record ( No one is equal or repeating) About 15 people in the field, which I usually need to use in questions, while others are used on occasion (~ 40% of the questions).

Should I set up 2 tables, and can join other and 1: 1 relationships with less common areas? Or would I just put them in a table?

Does any advantage, speed or otherwise, do one or the other?

Post-text "itemprop =" text ">

Two tables mean that 40% of your questions have been included and 60% are not included.

You

Your 40% of the questions are slow. 60% of your questions are fast for two reasons 1) None included 2) Low physical data block .

Is this performance different "important"? Does it "make things better"?

Unless you spend on each question A. Do not explicitly define time - and run benchmark tests to measure the difference - it does not matter.

> Before you can decide what "better", you can actually perform Will have to be built and measured.

MySql variables and php -

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne

c# - How can I find out if there are windows above a control? -

-
If I have Winforms controls, can it be possible to tell whether the window above it (from any application)? Actually, I have to know that some parts of my control are actually appearing on the screen. If you are happy to p / call, the EnumWindows function provides all top-level windows HWND on the screen is; This allows you to get a Non-Client Rectangle (GetWindowRect) to compare the limits of your form. This non-rectangular opaque areas (media player and fancy skins for choice), so you can be false positive for such a control window.

javascript - Classic ASP "ExecuteGlobal" statement acting differently on two servers -

-
I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
