Rename MySQL database I created a database with the name of hrms. Now I need to change database name to sunhrm. But, It is disabled in MySQL workbench. Can I do that on the Linux server itself?
How do I quickly rename a MySQL database (change schema name)? The MySQL manual at  covers this.  Usually I just dump the database and reimport it with a new name. This is not an option for very big databases. Apparently RENAME {DATABASE | SCHEMA} db_name TO new_db_name; .  This needs to work with , which stores things very differently than .
I have my bachelors degree in engineering science: computer science, option electrotechnic. I have a good understanding of basic mechanics and dynamics, calculus (differential equations).  The books I'm now having a look at are:       What book do you recommend for studying fluid dynamics on my own and why? How do I *really* justify a horizontal menu in HTML+CSS? You find plenty of tutorials on menu bars in HTML, but for this specific (though IMHO generic) case, I haven't found any decent solution:  #  THE MENU ITEMS    SHOULD BE    JUSTIFIED     JUST AS    PLAIN TEXT     WOULD BE  # #  ^                                                                             ^  #    There's an varying number of text-only menu items and the page layout is fluid. The first menu item should be left-aligned, the last menu item should be right-aligned. The remaining items should be spread optimally on the menu bar. The number is varying,so there's no chance to pre-calculate the optimal widths.   Note that a TABLE won't work here as well:   If you center all TDs, the first and the last item aren’t aligned correctly. If you left-align and right-align the first resp. the last items, the spacing will be sub-optimal.   Isn’t it strange that there is no obvious way to implement this in a clean way by using HTML and CSS? My Command is below and its print Free CPU and Used CPU below format.  I want to restrict awk output to 2 decimal place.  grep 'cpu ' /proc/stat | awk '{usage=($2+$4)*100/($2+$4+$5)} {free=($5)*100/($2+$3+$4+$5)} END {print "Used Cpu:",usage "%"} {print "Free Cpu:",free "%"}'   Output :   Free Cpu: 98.9588%  Used Cpu: 1.04125%   Desired output :  Free Cpu: 98.95%  Used Cpu: 1.04% Saving image from PHP URL If $f$ is continuous, nonnegative on $[a, b]$, show that $\int_{a}^{b} f(x) dx = 0$ iff $f(x) = 0$  "$\Rightarrow$" Assume by contradiction that $f(x) \neq 0$ for some $x_0 \in [a, b]$. Without loss of generality, assume that $f(x_0) &gt; 0$. Since $f$ is continuous, $\exists \delta &gt; 0$ such that $f(x) &gt; 0,  \forall x \in (x_0 - \delta, x_0 + \delta)$. Since $f$ is continuous on $[a, b]$, then it is Riemann integrable. Therefore $\int_{a}^{b} f(x) dx = \sup L(f, p)$ for some partition $p$. Now what I want to do is to show that the lower sum, $L(f, p) &gt; 0$, in that case its supremum is $&gt;0$, and that contradicts the condition that $\int_{a}^{b} f(x) dx = 0$. However, I don't know how to articulate it.  "$\Leftarrow$" If $f(x) = 0, \forall x \in [a, b]$, then $\int_{a}^{b} f(x) dx = \int_{a}^{b} 0 dx = 0$ Do scimitars and rapiers count as swords for the magic items in the 5E DMG? Are rapiers and scimitars considered swords for magic items like:   Dancing Sword Defender Dragon Slayer Flame Tongue Frost Brand Giant Slayer Holy Avenger Luck Blade Nine Lives Stealer Sword of Life Stealing Sword of Sharpness (scimitar) Sword of Vengeance Sword of Wounding Vorpal Sword (scimitar)   Or are only shortswords (not Sword of Sharpness or Vorpal Sword), longswords and greatswords swords for these items and therefore available? What are C++ functors and their uses? I keep hearing a lot about functors in C++. Can someone give me an overview as to what they are and in what cases they would be useful? 750Gig Hard Drive shows full with only 315Gigs used Are players allowed to pass a penalty kick? How to assign same Data to multiple object copies I made many copies of an object, then I thought it would've been better if I made them to share the same Data (being an instance of the same original object), I know how to do it one by one, is there a way to do it for all of them at once? I tried Copy Attribute add-on but didn't find what option can do that, or even if this is possible in the first place. Stars and pins are retained when chat messages are moved! I tried to open Software Center using the command line   software-center   and it did work. I mean, Software Center opened and works fine, BUT, at the same time, in the Terminal window I see a lot of strange errors. How can that be? I'm puzzled.   Is there any explanation for this (and a fix for it)? I repeat, the app does open and it works fine, is only the lines in the background that show that something is not all right.  Here are the screen-shots with all the lines. How to print results in SQLcmd window Plural nouns in nominal compounds I wonder whether there are rules or guidelines regarding plural nouns in nominal compounds. For example a compound university students list. If there are many lists and many universities is it grammatically correct to say universities students lists? Must all elements be in the plural form or can some be left in singular, even though the meaning is plural? I've seen an expression universities student lists; is it correct?

I remember reading this one article about database design and I also remember it said you should have field properties of NOT NULL.  I don't remember why this was the case though.  All I can seem to think of is that, as an application developer, you wouldn't have to test for NULL and a possible nonexistent data value (for instance, an empty string for strings).  But what do you do in the case of dates, datetime, and time (SQL Server 2008)?  You'd have to use some historic or bottomed-out date.  Any ideas on this? find the minimum value given constraints I am looking for a package to create bullet gauge graphs, but I couldn't find any.  A bullet graph looks like this:    and an ample description/specification can be found   It is available in Mathematica 9 ()  Is it possible create this kind of graphs in a easy way with TeX (like Matehmatica 9 or similar)?
