DB Design :: Error - Cannot Connect To A Database
Jun 15, 2015
I am trying to connect to the database but it gives the error cannot connect to database.Login failed for user....
This is my connection string in code behind :
[string constring = "Data Source= localhost; Initial catalog= Database.mdf; Integrated Security= True";
SqlConnection con = new SqlConnection(constring);]
This is my connection string in web.config:
<connectionStrings>
<add name="Database" connectionString="Data Source= localhost;Initial catalog=Database.mdf;Integrated Security=True" providerName="System.Data.SqlClient"/>
</connectionStrings>

Hello,
I'm a a newbie on this so I am a bit lost...
I have had SS2005 on my machine and running fine for sometime now. Today when I tried to connect to it, I get the following error:
TITLE: Microsoft SQL Server Management Studio
------------------------------
An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)
------------------------------
ADDITIONAL INFORMATION:
Possible schema corruption. Run DBCC CHECKCATALOG.
A severe error occurred on the current command. The results, if any, should be discarded. (Microsoft SQL Server, Error: 211)
For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&EvtSrc=MSSQLServer&EvtID=211&LinkId=20476
------------------------------
BUTTONS:
OK
------------------------------
The only thing I think I did new was I had previously run a SQL Script to install Northwind. However, after I did that, everything was still running fine.
I don't even know where to begin looking to fix this.
Thank you for the help.

I am using Visual Studio 2005 express and SQL Server express
Find here the code :
Dim MaChaineConnection As String = "Persist Security Info=False;Integrated Security=SSPI; database=BaseDonnes; server=.SQLEXPRESS"
Dim MaConnection As New SqlConnection(MaChaineConnection)
Dim Instruction As String = "insert into TableNom (Nom, Prenom) values ('Name', 'FirstName')"
Dim MaCommande As New SqlCommand(Instruction)
MaCommande.Connection = MaConnection
MaConnection.Open()
MaCommande.ExecuteNonQuery()
MaConnection.Close()
Find here the error message :
Cannot open database "BaseDonnes" requested by the login. The login failed.
Login failed for user 'ASSOCLEROYSTDM'.
It first seems that I need to indicate my login and password but I am connecting to SQL server with Windows authentification!
so what ?
When changing connection string into
Dim MaChaineConnection As String = "database=BaseDonnes; server=.SQLEXPRESS; user=stdm; password=stdm"
the message is :
Login failed for user 'stdm'. The user is not associated with a trusted SQL Server connection.
So please help me ....
Did I forget the parameter anything ?

Hi!
I just have downloaded VWD C# express and get a big problem when I try to connect to a database, I use the SQL data source object and when I'm trying to connect to a database I can't use the INSERT, DELETE and UPDATE object in the database.
I now that I have to click to advanced button and click for INSERT, DELETE and UPDATE objects but I don't even can click for that so something is very wrong, but what?
I use Microsoft SQL server database file as a data source and if I try to use Microsoft SQL server (sqlclient) instead I get this huge error:
"
An error has occured while establishing a connection to the server. When connection to SQL Server 2005, this failure may be caused by the fact that under the default SQL server does not allow remote connections. "
(provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)

Ok so I'm using the Management Studio Express and was able to log in and get into the database server, but I had to click the "options>>" button and change database I wanted to connect to from <<default>> to my database on the server or else I get the "cannot open user database, login failed" error message.Then I right click my database and it gives me the "Cannot open user database. Login failed" error message, even though I already connected to the database to login during the connect screen. Also I'm able to interact with the database using SQL QUERIES in the Management Studio, like adding new tables with it, but if I right click the database and click "add table" I get that error.What gives? I know I have permission since I was able to log on, and modify the database using SQL queries but if use the GUI I can't use it. I can't even right-click select "properties" without getting that error. The reason I want to use the GUI is because I want to right click and use the backup feature of the database.My guess is that Management Studio continues to point to the default database(which gives me that message) after I already logged in, so I have no idea how to change the default database that management studio points to, to the one I do have permission to use. Thanks in advance.

In my string below, my forum setup up file, setup.asp , when run delivers an error that it is unable to connect to the database. Error: 800004005
I am running this from within IIS 5.0 aon a Windows 2000 Server, by right clicking the file in IIS and choosing "browse" I am trying to set this up so user IUSR_SERVER_NAME can "read and Write" to the database or instance I have created called rpggamerpro. The authentication in the SSSAC is set to use both Windows and SQL Authentication for the "master". I have set permissions on the folder which contains the SQL 2005 Express installation and database for IUSR_SERVER_NAME to read/write. I have created a IUSR_SERVER_NAME user in the Security/User directory for the database or instance "rpggamerpro" and gave the user read/write permissions there. So I am still at a loss as to what permissions, strings, settings, configuration or whatever the heck else needs to be done in order to get this thing to work. Please anyone willing to help a realative new commer to the SQL and DB world would be greatly appreciated.
trConnString = "Provider=SQLOLEDB;Data Source=nssqlexpress;database=rpggamerpro;uid=IUSR_NS;pwd=;" '## MS SQL Server 6.x/7.x/2000 (OLEDB connection)

I installed SQL 2005 including backward compatibility, MSDN libraries and SP2 a new Windows 2003 server (chose mixed mode authentication). Installation was successful and I then installed an off the shelf database with Windows authentication which also installed successfully.
I created a new group in AD, added the database users into the group and gave db-owner rights to the group in SQL as advised by the installation guide. However, when I try to open the database it gives an error message saying "Cannot open database.[DBNETLIB][ConnectionOpen(Connect()).] SQL server does not exist or access denied". I also tested it adding an individual user (myself) as a user to no avail.
When I set up DSN in ODBC on my computer I can successfully test the connection but can't run the application. The connection is via TCP/IP.
Any suggestions?

Ok, I'm doing a football database for fixtures and stuff. The problem I am having is that in a fixture, there is both a home, and an away team. The tables as a result are something like this:
-------
Fixture
-------
fix_id
fix_date
fix_played
----
Team
----
tem_id
tem_name
-----------
TeamFixture
-----------
fix_id
tem_id
homeorawayteam
goals
It's not exactly like that, but you get the point. The question is, can I do a fixture query which results in one record per fixture, showing both teams details. The first in a hometeam field and the second in an away team field.
Fixture contains the details about the fixture like date and fixture id and has it been played
Team contains team info like team id, name, associated graphic
TeamFixture is the table which links the fixture to it's home and away team.
TeamFixture exists to prevent a many to many type relationship.
Make sense? Sorry if this turns out to be really easy, just can't get my head around it at the mo!

This has worked fine for weeks, and months.
I'm running Vista Ultimate. SQL 2005 is set as my Default instance, and SQL2000 is set as (local)SQL2000.
Today, actually half way through today, I restarted my computer after installing Photoshop Updates.
Upon getting my computer back up and running, I cannot access SQL2000 from any website on my computer, nor can I access it from SQL2005 Management Stdio. I CAN access it from Enterprise Manager (SQL2000 tool).
Whenever I run an web app that connects to it I get this error:
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
Now I usually get these when ASP.NET can't point to the right spot, but in this case I'm pointing exactly where I need to go. Any thoughts?
--Edit
I should also add my password got changed a few days ago on our Domain. This was the first time restarting after the PW change.

I would like to fail a package depending on the error. The package extracts data from Excel files. I would like to continue processing if an Excel file is badly formatted, but stop processing if there is a serious issue. like the file server hosting the Excel files crashed.
I was thinking about dynamically changing the MaxeErrorCount property based on the Error ID or description.
Any ideas on an intelligent/simple way to do this

Hello everyone,I have a webcontrol that uses database-structures alot, it uses the system tables in SQL to read column information from tables. To ease the load of the SQL server I have a property that stores this information in a cache and everything works fine.I am doing some research to find if there are anyway to get information from the SQL server that the structure from a table has changed.I want to know if a column or table has changed any values, like datatype, name, properties, etc.Any suggestions out there ?!

I have a system that basically stores a database within a database (I'msure lots have you have done this before in some form or another).At the end of the day, I'm storing the actual data generically in acolumn of type nvarchar(4000), but I want to add support for unlimitedtext. I want to do this in a smart fashion. Right now I am leaningtowards putting 2 nullable Value fields:ValueLong ntext nullableValueShort nvarchar(4000) nullableand dynamically storing the info in one or the other depending on thesize. ASP.NET does this exact very thing in it's Session State model;look at the ASPStateTempSessions table. This table has both aSessionItemShort of type varbinary (7000) and a SessionItemLong of typeImage.My question is, is it better to user varbinary (7000) and Image? I'mthinking maybe I should go down this path, simply because ASP.NET does,but I don't really know why. Does anyone know what would be the benifitof using varbinary and Image datatypes? If it's just to allow saving ofbinary data, then I don't really need that right now (and I don't thinkASP.NET does either). Are there any other reasons?thanks,dave

Hi All,
I am designing database where few of the master tables will reside in different database or in case different server. Scenario is
Server "A" with Database "A" may host the "Accounts" table.
Server "B" with Database "B" may host the "Product" table.
I am designing database "Project" which will hosted in Server "A".
My application requires this master tables [readonly access] as data inserted in my application refers this tables. Also there are reports to be generated which refer this tables.
How do i design my database and sql queries?
I am thinking of approach of having equivalent tables created in my database and writing service which keep tables in my database in sync. This will ensure good perfomance during transaction and reports as they will need to refer this table locally as opposed to different database or different server.
Any thoughts on above approach?? or any better/standard way for such scenarios ?
Thanks in Advance. Your inputs will be of great help.

Hello:
My client has a db with the following structure:
Online US Searchable Map of the 50 US States. Users search criteria is the following: Query records by selecting state, county, then record. Each County table has 10-20 tables. All databases combined = 500MB and TLogs = 100MB.
How would you re-design a relational DB where users could query data by state-county-record. Currenty the DB's are created by the County of each state which creates hundreds of DB's in SQLServer with no realtionship to each US state. What would be the best design to ensure good performance, data integrity and maintenance? Would you create 1 DB with all 50 states, create 4 DB's and divide by region(N,S,E,W), 50 DB's of each state or leave it as is with each county it's on DB? Any suggestions would be appreciated.
thx

Hi,
I need a hand with designing a database.
I am collecting results from a survey which has the following questions:
Call ref? How did you place your support call? Were you satisfied with the amount of time you had to wait until getting acknowledgement of the support call placed? 1 = very satisfied and 10 = very unsatisfied. How happy were you with the customer service you received upon placing the support call? 1 = very unhappy and 10 = very happy.How satisfied were you with the amount of time you had to wait until you heard from an engineer? 1 = very satisfied and 10 = very unsatisfied. How satisfied were you with the time taken to get your problem/query resolved? 1 = very satisfied and 10 = very unsatisfied Did you feel the engineer had enough knowledge to deal with your call? 1 = very good and 10 = not very good Overall how satisfied were you with the support call placed? 1 = very satisfied and 10 = very unsatisfiedIs there anything we can do to improve the quality of the support and service you received?
I want to store this in a database. Obviously I want to use best practice for design, normalisation etc. The stumbling block I am coming accross is the fact that each question has a number and each question has a score from 1 to 10 and storing this in the database. Any help appreciated!
Thanks

I am creating database tables for company testimonials. Database columns: name, position, companyname, comment, service we provided.
My question is that for each company - may have a multitude of different services from us, and different people with different positions in the same company may make comments.
What is best practice for putting this db structure together?

I guess I am confused about something and need some help. I am looking at a database schema for about 20 tables in a database. I noticed that the firstcolumn in each table Is some type of Id. For example StudentId,TestId etc.Where the Id is a unique numeric sequential value.
So I have some questions?1- Do these Id's act as what are called indexes for the table?(Unique indexes)2- If the answer to 1 is correct, then how do I create these unique indexes? Is it as simple as declaring the Id column as the primary key and that this value will be generated automatically upon insert? 3- Is it necessary to have an Id column for every table, or may I only do it for a few of them?4. In relation to Question2, what do I need to do, so that the Id column will automatically be created when someone inserts a value into the database table with an ID column.
For example here are two sample tables
StudentsInfo
StudentId<PK> Name Age 1 Mark 33 2 Jill 23 3 Mary 25
PersonalInfo
Name<FK> SocialSecurity Address MajorMark 324-444-3342 15 Elm ArtJill 888-888-8998 21 North ScienceMary 876-777-2344 18 Byle Music

PackagesPackage A:Acer centrino 1.63COM 4x125 hours Wi-fi accessPackage B:Acer centrino 1.733COM 4x150 hours Wi-fi accessI made a table for the items having the following fields: Item_ID, Item_Nameand another for the Models having: Model_ID, Model_Name, Item_Type(Foreign Key to Items table)up to this point is this correct?About the packages table, I don't know if it is correct to have a field for each model (one for notebook, other for modem, and other for wireless card) like this it would be like having 3 foreign keys to the same table but nothing distinguishes themI don't know how to relate the packages and the models table.Any recommendations for a proper design for those entities?
