DataSource Controls :: Single Owner On Both .mdf And Log File?
May 2, 2010
I'm working on my private website(using VS2008) which is connected to a simple database(using SQL management studio 2008). The database is currently located in the App_Data folder and the connectionstring should be quite simple;
[Code]....
After reading several forum threads I have changed the following;- Permission (locating the db and going into security, removing current users and adding me (local) to it as single owner on both .mdf and log file.
I am getting the error message "SELECT permission denied on object 'MyTable', database 'MyDB', owner 'dbo'.", when trying to run a small asp.net application via a browser where i work.
I built it on my local machine(VS 2008, C#) and transferred over to an IIS server(i.e. Windows Server 2003) and I have also enabled the application folder in IIS.
It runs fine on my local machine. Connection string in web.config on my local machine <add name="connstring" connectionString="Data Source=DBASE;Initial Catalog=MyDB;Integrated Security=true" providerName="System.Data.SqlClient"/>
on the server, connection string is <.......;User Id=userid;Password="mypassword" />.
But when i swapped connection string on server to use <Integrated Security=true>, and tried to run from a browser again, i get:
Login failed for user 'SVRSERVERNAME$'
I have a couple of other apps I built in the past and they are running fine, I didn't do anything special, just transferred them as normal to server and ran through browser
In fact, one of my previous apps even uses the same table and database. but with this new app, I don't know why it wouldn't work even though it runs perfect on my local machine
I can access the database manually from SQL Management studio, i connect to it using my Windows account or the given username/password credentials.
Other thing I noticed, when I changed the connection string on my local machine web.config to use <User Id=userid;Password="mypassword">, i then get same error as if it was running from the server:
SELECT permission denied on object 'MyTable', database 'MyDB', owner 'dbo'.
For context: First of all, I am new to LINQ, as I have been using SubSonic for quite some time now.
I have two tables, Users, and Affiliates. They both have a very typical schema. The FK that joins them is the UserId field, which is in the Affiliates table. I want to create a LINQ query that pulls the Username from the Users table using the AffiliateId value. The AffiliateId is a primary key of the Affiliates table.
I have tried to accomplish this using many variations of the following code:
[Code]....
In the above query, I expect to get a single row result set. However, I instead receive the entire table of results.
How can I make this work? I have yet to see an example or article out there to do what I am trying to do.
I have huge excel files that I have to open from web browser. It takes several minutes to load huge file. Is it possible to open a single worksheet (single tab) at a time from excel file that contains many worksheets? I have to do this using C# / asp.net MVC
I wanted to know is it possible to pass "SqlDataSource" data to a variable? if not how can i use datareader to do this?
i couldn't figure out how to pass SqlDataSource to a varialbe so i tried use datareader and i'm stuck in middle of it, also my query only returns one row and one column so i rather not to use array if possible. here is my code:
Table1 - user master table. table2 - transaction table. Now I want to write a single query which will give results like table 3. how to write single query.
I have 2 tables. Table_A has one to many relationship with Table_B.
For example. Table_A has an ApplicantKey and in Table_B I am storing (Resume_name and CoverLetter_name for the Applicant). Joined by ApplicantKey
Now when I join them and execute the query obviously it returns me two rows. But what I want is that it should return only one row with Columns like Resume_name, CoverLetter_Name
i develop a c# windows application. My database is sql server 2008 exp. i want lock single row for user select it for update. for example;
userA - Connection a (connection id 52);
user select a single row (select * from t1 with(rowlock?, updlock?,or what) where id=1) and bind data to form fields (texbox, checkbox,combobox etc.). (there is no problem)
userB - Connection b (connection id 54);
userB can select all other rows from t1 (where id=2 or 3 or anything) but not id=1. when userB select * from t1 where id=1 system generate an exception with (you cannot select this row because it is updated. Updated users connection id is 52.)
when userA (connectionid52) close form or commit changes then userB can select id=1.
i am read few documents (transacions, rowlock,updlock, concurrency violation optimistic,pessimistic) but i couldn't understand.
I've managed to connect to the database and return a record based upon a login name. I can itterate through the rows printing out the password but I know there's only 1 row (or can test for that) so how do I get the value of the password for the one row without the loop?
Dim supervisorAdapter As New SupervisorTableAdapters.SupervisorTableAdapter Dim supervisors As Supervisor.SupervisorDataTable supervisors = supervisorAdapter.GetSupervisorByLogin(login) For Each count As Supervisor.SupervisorRow In supervisors Response.Write(count.password) Next
This works great for 1 parameter SqlDataSource1.SelectParameters("City").DefaultValue = Me.Page.Title
But I can't figure out how to pass in two parameters in a single statement (See the Select Parameters Below) Two paremeters (City, and Classification) If I set the page title to say "Bismark Charters" Bismark = City & Charters = Classification [Code]... </SelectParameters >
SQLCommand cmd = new SQLCommand("insert into customers name values ('"+textbox1.Text+"')",conectionstring); cmd.ExecuteNonQuery();
now when people enter a (') single quote, this doesnt work. how do i avoid this error as this is driving me nuts!! i cannot prevent users from entering single quotes as names like "O'Connor" contain a single quote. parameterized query doesnt seem to be the best solution as it involves loads of coding and will involve huge changes in the code. as its not a fresh app im making... can some modification in the code above so this can be avoided?
I'm attempting to hook up multiple DropDownLists to a single SQLDataSource, but I want the SQLDataSource to return different rows depending on which DropDownList it is populating.
Say I have a table full of names (we'll call it TABLE_NAMES):
[code]....
....and I have two dropdown lists, one with a list of person names and one with a list of dog names.
Is there a way to link up each of these dropdown lists to a single SQLDataSource and use the SelectParameter to differentiate between which records I want returned for each dropdown list?
To make matters worse, these dropdown lists will appear within a GridView control....so there will be multiple instances of each dropdown list depending on how many rows there are in the GridView.
I have a ListView that displays comments for an article.Each comments has a button that, when clicked, deletes that comment provided that the logged person is the comment's owner or an administrator.
I need a way of storing comment's ID in the ListView somehow and then I need to check if the ID of the comment's author is the same as the ID of the logged user (which is stored in the Session) and then, if they match, display the button that deletes the comment when clicked.
After creating a dataset, which has CRUD statements generated two or more tables, which Data Control should I use that will allow me to insert data into fields into 2 or more tables from a single web form. I'm trying to create a web form that will allow the user to input student information, such as general information, medical information, etc.
Here's a stored procedure I created that uses another stored procedure inside it to return a value:
[Code]....
Note the 'exec dirinfo.dbo.d_searchempbyname @TicketSubName' part. That stored procedure will return a single record. What I need is to get a single column from that recordset (in this case, the email address of the employee), and store that value in a variable.
I need to run a select statement on log in event and store the value of the select statement (returning one item) in a session variable.Do I have to u sqldatasource for this.. or is there someway I can run a single select statement and store the resulting value in a variable?
