The situation is I have two schemas: A and B. I have a restricted user that I need to give a privilege do SELECT queries in B schema and just it. How can I grant this user?
I need to grant select permission for all tables owned by a specific user to another user.  Can I do this with a single command along the lines of:  Grant Select on OwningUser.* to ReceivingUser   Or do I have to generate the sql for each table with something along the lines of:   Select 'GRANT SELECT ON OwningUser.'||Table_Name||'TO ReceivingUser'   From All_Tables Where Owner='OWNINGUSER'
Let $x*y=\gcd(x,y)$ on $D_n=\{x\in \mathbb N:x |n\}$. I have to prove that $(D_n,*)$ is a commutative monoid and I have a problem when finding the identity element.  $x*e=x$  So $gcd(x,e)=x \to e=xk,k\in \mathbb N^*$ and $e \leq n$  A good $e$ is $0$ but it's not in $D_n$ Can you deliver it [when,after] it [is | will be] assembled? How do I withdraw all money from my HSA account as a non-resident? I have lived in US for 5 years, and I (still) have an HSA account with BoA. Now I am living in Europe, and there's a fat chance I'll ever go back to live in US, so I would like to withdraw the money from my HSA, pay the due taxes, of course, and just be able to use them. How exactly I go about that?  Thanks in advance. Can a dual national visit USA under VWP after visa refusal for other nationality? Recently I was refused an E-2 visa under Section 214b. To be honest I don't really know why because I have strong ties with my home country (house, bank account, family) so my lawyer sent an appeal to the legalnet and I'm  waiting for an answer.  I have a second nationality that I used to travel in USA within the last 15 months under ESTA. A few days after my E-2 refusal I checked my ESTA status  and it is still authorized.  Can I travel to the States right now or not?  I have a purchased business over there and have to take care of my assets. Difficult Polynomial Question I'm a first time Linux user. My laptop wasn't connecting to the wifi so I followed the instructions from .  On typing sudo apt-get update after that, I got this error:  E: Type 'sudo' is not known on line 2 in source list /etc/apt/sources.list E: The list of sources could not be read.   What can I do? How do I format a Decimal to a programatically controlled number of decimals in c#? $g\in G$ maximal order in $G$ abelian then $G=\left\oplus H$ If $g\in G$ is an element of maximal order in a finite abelian group $G$ then exists $H\leq G$ such that $G=\left&lt;g\right&gt;\oplus H$  Attempt: Using fundamental theorem I know that $G=C_{n_1}\times\cdots\times C_{n_k}$ where $n_i|n_{i+1}$. With some work I proved $|\left&lt;g\right&gt;|=n_k$, so $C_{n_k}\cong \left&lt;g\right&gt;$. Then $G\cong H\times \left&lt;g\right&gt;$, but this is not an equality. Graphical interpretation of LASSO How to set tick label precision Evaluating $\int_0^\infty \frac{\log (1+x)}{1+x^2}dx$ Can this integral be solved with contour integral or by some application of residue theorem? $$\int_0^\infty \frac{\log (1+x)}{1+x^2}dx = \frac{\pi}{4}\log 2 + \text{Catalan constant}$$  It has two poles at $\pm i$ and  branch point of $-1$ while the integral is to be evaluated from $0\to \infty$. How to get $\text{Catalan Constant}$? Please give some hints. Why was Arcanine with the Legendary Birds in Veridian City in Pokémon Origins? In Pokémon Origins, Red sees a image with the three legendary birds and Arcanine.     Why was Arcanine there? I mean, he's 'The Legendary Pokemon' but not a legendary Pokémon. In , there is a comment by  on the answer that Arcanine was originally a legendary Pokémon:     "...Nintendo first gave Zapdos, Articuno and Arcanine as the legendary trio. But they removed Arcanine as it would have been awkward. Two birds and a dog, huh!..."   This still does not add up because Pokémon Origins was created a while after they removed Arcanine. Any thoughts? Consider this situation:  A ball is moving forward and undergoing rotation. Assume that it is not slipping. Eventually, the velocity and rate of rotation of the ball decrease, and it comes to a halt. But if you observe the direction of friction (when the ball is rotating clockwise), you will see that the friction should have provided a clockwise torque to the ball and the angular velocity of the body should have increased. But this doesn't happen. Why? How to access the Index Of A Generic.List By Reflection? ok, ive a class and i pass an object as property.  the object that i pass is a List&lt;X&gt;  in my class im trying to access the Object index by reflection BUT I CAN'T!!!   Example:  this class works i just wrote down the part i want to show you and i need help.  class MyClass {     private object _recordSet;     public object RecordSet     {         get { return _recordSet; }         set { _recordSet = value; }     }      public string Draw()     {         system.reflection.Assembly asem = system.reflection.Assembly.getAssembly(_dataSource.GetType());          object instance;          instance = asem.CreateInstance(_dataSource.GetType().UnderlyingSystemType.FullName);          //to access de Count of my List         int recordcount = int.Parse(_dataSource.GetType().GetProperty("Count").GetValue(_dataSource,null));          //i need to do a          for(int cont = 0; cont &lt; recordCount; cont++)         {             _dataSource[cont].Name; // &lt;-- THIS PART IS NOT WORKING!!! because i cant access the Index Directly.... WHAT TO DO!! ???         }     } } How to disable windows snap target In a fresh install of Windows 10 Pro. When I drag a window a snap target position image is displayed. See image.    This is very frustrating as the image is often displayed under the place where I want to place the window. The affect being that the window is therefore snapped and not placed where I intended it to be.  How do I disable this?  To be clear I don't want to disable snapping altogether just the annoying destination image underlay  UPDATE  I do not have the option to "Allow the system to suggest companion windows when using Snap" WPF DataGrid : CanContentScroll property causing odd behavior A while back I read about the super Kamiokande detector detected a large neutrino flux and then several hours later a supernova was seen. Anyone know of this with sources? I don't recall the source at the moment. Inversion in "only [adverb] have they" I have seen this construction quite often:      Online ads have been around since the dawn of the Web, but only in   recent years have they become the rapturous life dream of Silicon   Valley.   What is the rule there?. When your sentence doesn't start with pronoun + verb, invert them as verb + pronoun?. I know it sounds awkward but is it possible (grammatically correct) to use something similar to:      Online ads have been around since the dawn of the Web, but only in   recent years they have become...   And in any case, does this only work with have (or has)? Maybe it works fine with 'had' but I can't think of an example right now. Show that any set in a metric space can be written as the intersection of open sets Uniform convergence of $\sum\limits_{k=1}^{\infty}\dfrac{kf(x^2)}{1+k^3f(x^2)^2}$
