Using M code get data from SQL has credential error - sql

I tried to connect data from SQL Server in my local using M code in Power Query. I can't see the difference between 2 codes, the first code connect and get data OK but the second code has error about credential. Pls tell me why it is
First code:
let
Source = Sql.Database("MyServer", "AdventureWorksDW2014"),
dbo_FactFinance = Source{[Schema="dbo",Item="FactFinance"]}[Data]
in
dbo_FactFinance
Second code:
let
Source = Sql.Databases("MyServer"),
AdventureWorksDW2014 = Source{[Name = "[AdventureWorksDW2014]"]}[Data],
dbo_FactFinance =
AdventureWorksDW2014{[Schema = "dbo", Item = "FactFinance"]}[Data],
in
dbo_FactFinance
The error of the second code:
thank you guys so much!!

Most likely your account has rights only for AdventureWorksDW2014 database.
In the first code snippet, you are connecting directly to AdventureWorksDW2014 database. In the second, you are connecting to the default database (usually this is master) and then the connection is switched to AdventureWorksDW2014 database. So if the login on the SQL Server for your account has only public server role, and has user mapping to AdventureWorksDW2014 (e.g. db_owner, db_datareader, etc.), then you must either use the first code, or to set the default database for your login to be AdventureWorksDW2014.
For more information take a look at Create a Login.

Cannot remove SID from User Mapping of Login object

During some testing I applied SID value 0x01050000000000051500000085E77E2F11C35F7307E53B2B531D0200 of a system account received from SUSER_SIDfunction to User Mapping of a certain Login object in SSMS. Now based on that I cannot get rid of it as I keep getting an error message Value was either too large or too small for a UInt64 no matter what I enter or erase. I would appreciate if somebody would know how to get rid of a certain User Mapping either via UI or code specially when I encountered such an error message, thank you
Your actions were:
Open login properties of some windows login
Changing the corresponding user for some database to sid (why on the erth did you map the login to the user named as sid???)
This corresponds to the following code:
alter user... with name = [0x01050000000000051500000085E77E2F11C35F7307E53B2B531D0200];
Now you want to do the inverse action, so you need to execute this code:
use CDR_MDS;
alter user [0x01050000000000051500000085E77E2F11C35F7307E53B2B531D0200] with name = NAME=[GROUP\gg ORG RAACO MS BI Team];

Removing a user from backend created by IdentityServer4

I am debugging confirmation email flow when signing up a new User in Asp.Net Core web application with Identity Server 4.
Since I had already signed up with my actual email, to reuse it, I modified the UserName and Email in AspNetUsers table using SQL Update to some random value.
Now when I am signing up with the original email again. I am getting a duplicate user error
result = await _userManager.CreateAsync(user, model.Password);
I have already:
Cleared browser cache.
Closed local IIS Express
Restarted Visual Studio.
Used_userManager.DeleteAsync() after updating the UserName and Email back to original values but this gives an Microsoft.AspNetCore.Identity.IdentityError with description Optimistic concurrency failure, object has been modified.
On running this query on Sql Server
select * from INFORMATION_SCHEMA.COLUMNS where COLUMN_NAME in ( 'UserName' , 'Email')
I get the following:
I know that this is not a good practice to mess with backend, but this is development environment and I could continue my work with another email.
I would request readers to help in understanding how the User could be safely scorched to be able to reuse the email.
Appreciate your time
I agree with Kyle's comment and to further speed up your debug process you should note that if you use gmail to do this you can debug this process using one email.
from google/gmails perspective myaccount#gmail.com == my.acount#gmail.com == m.y.a.c.c.ount#gmail.com etc etc just try it out, google disregards all period characters in the email. you can enumerate/exhaust ~2^8 emails (in this example) if you just enumerate through the local-part of the e-mail address. but from your applications side, myaccount#gmail.com is not the same as my.account#gmail.com, ie they are different user accounts. Basically you can use one email to test out this feature of yours without having to delete the user.
Here is how I did it and finally got passed the pesky "concurrency failure" error message... This works in ASP.NET CORE 2.2
Obtain the user object through the FindByName method first.
Remove the user from their assigned Role (in this case I hard coded "Admin" because that is the role I'm interested in but fill in your own), then delete the user.
//Delete user.
//Obtain the user object through the FindByName method first.
//Remove the user from their assigned Role, then delete the user.
var userManager = serviceProvider.GetRequiredService<UserManager<ApplicationUser>>();
ApplicationUser delAppUser = new ApplicationUser
{
Email = "SomeEmailForindividualAdminUser",
UserName = "SomeUsernameindividualAdminUser"
};
Task <ApplicationUser> taskGetUserAppUser = userManager.FindByNameAsync(delAppUser.UserName);
taskGetUserAppUser.Wait();
Task<IdentityResult> taskRemoveFromRoleAppUser = userManager.RemoveFromRoleAsync(taskGetUserAppUser.Result, "Admin");
taskRemoveFromRoleAppUser.Wait();
Task<IdentityResult> taskDeleteAppUser = userManager.DeleteAsync(taskGetUserAppUser.Result);
taskDeleteAppUser.Wait();

(Google App Script) Can i give access to other users to my private Spreadsheet with oAuth?

i need help for my application "Google App Script".
I am the owner of a Spreadsheet that I use as a DB in my application; this spreadsheet must remain private.
My application is executed as Gadget in Google Site, in this application a user runs the script as himself (not under the owner's identity).
I need that all users who access the application can get some data from the DB Spreadsheet.
How can users get this data, if the Spreadsheet is only accessible to me?
Can I use oAuth?
Sorry for the bad English
Following Zig answer and to illustrate, here is an example of such a contentService webapp, one can call it with this url either in a browser or in urlFetch
The app is deployed as follows : execute as me and anyone can access even anonymous
https://script.google.com/macros/s/AKfycbxfk5YR-JIlhv7HG9R7F-cPxmL0NZRzrdGF4VFGxGivBkYeZY4/exec?&user=chris&row=4&sheet=Sheet1
and here is the demo script
function doGet(e) {
if(e.parameter.user!='serge' && e.parameter.user!='chris' ){return ContentService.createTextOutput("logging error, you are not allowed to see this").setMimeType(ContentService.MimeType.TEXT)};
var sheet = e.parameter.sheet;
var row = Number(e.parameter.row);
Logger.log(sheet+' '+row);
var ss = SpreadsheetApp.openById("0AnqSFd3iikE3dENnemR2LVFMTFM5bDczNGhfSG11LVE");// this sheet is private but anyone can call this app
var sh = ss.getSheetByName(sheet);
var range = sh.getRange(row,1,1,sh.getLastColumn());
var val = Utilities.jsonStringify(range.getValues());
var result = ContentService.createTextOutput(val).setMimeType(ContentService.MimeType.JSON);
return result;
}
No you cant use oauth from the gadget as the user doesnt have read permission.
However you can publish a second script to extract needed data that runs as you with anonymous public access and call that one with urlfetch from the 1st. Slower thou.

DropboxUnlinkedException but the session already had token inside and user didn't revoke the access

My problem is I have existing user in database which store the key and secret from the first authentication. I wish to reuse it again when I come back. For the first time authentication, everything working fine. I can use every method call from Dropbox API and the Token(key and secret) was stored in database.
I come back to app and get the Token from database, set it to the session, link current session with API.
session = new WebAuthSession(appKeys, ACCESS_TYPE);
api = new DropboxAPI<WebAuthSession>(session);
String userKey = dropboxUserObj.getUserKey(); //Key from database
String userSecret = dropboxUserObj.getUserSecret();//Secret from database
AccessTokenPair userAccessTokenPair = new AccessTokenPair(userKey, userSecret);
session.setAccessTokenPair(userAccessTokenPair);
It return DropboxUnlinkedException to me when I want to get user data from api using
String userDisplayName = api.accountInfo().displayname;
I have checked on debug mode. Api was linked with the current session. The current session stored Appkey and user's token and correct access type. The point that I doubt is I saw "client = null". I maybe forgot something but I check them all, try every possibilities I can think of but it still return me "DropboxUnlinkedException" which mean I haven't set an access token pair on the session and I didn't revoke access for sure.
Please help me figure out...
I added a screenshot maybe it can illustrate my problem

Login failed for user using SQL authentication

I have a connection made with a user name say ABC. In a method I create a new instance of sqlconnection named connection1 using the same connectionstring as that of the previous connection. When connection1.open() is issued it gives an exception stating that Login has failed for the user ABC. When SQL is able to connect to the user ABC for the first connection why does it fail for the second? I am using MARS=true in the connectionstring.
Thanks
What is the exact error please? And the code?
You could be connecting to a database where you have no rights, which gives a different error to a wrong password.
