mysql - Does anyone have considerable proof that CHAR is faster than VARCHAR? -


Is there any benchmark, graph nothing? All academic and theoretical on the web

OK, this is not the first time that this question has been asked, do they all say that CRAR results are used faster? I also read in MySQL books, it's all the same, but I did not come in any benchmark that proves this.

Can anyone put some light on this?

This is the simple argument, to simplify I will take the example of a CSV file ...

Will it happen faster

1231; 231; 32345; 21312; 23435552; 1231; 1; 243; 211; 3525321; 44343112;

Or this one

12, 23; 43; 56; 56; 76; 54; 83; 45; 91; 28; 92 As long as you accurately define your length, the variable should be fast as the predefined formats help in processing time.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
