how do you draw an E-R diagram from a bunch of functional dependencies?
I mean, where do you start? Can I just pick, say, E to be the starting point and have branches coming out to all the other attributes?
I need to write a code for remove dependencies between Table1.Prikey and Table2.Idand add dependencies between Table1.Prikey and Table3.Id how to write the code? please help .. thank you very much
View 2 Replies View RelatedI have created a database with several tables. I want to create a database diagram to show the relationshipbetween the tables. Below are the steps from the SQL Server 2005 documentation on how to create a database diagram. The problem is that when I right click on the Database Diagrams folder I am only given two options. They are:"Working with SQL Server diagrams" and "Refresh"There is no menu choice to create a new database diagram. Can anyone tell me what the problem here is?
To create a new database diagramIn Object Explorer, right-click the Database Diagrams folder or any diagram in that folder.
Choose New Database Diagram on the shortcut menu.
The Add Table dialog box appears.
Select the required tables in the Tables list and click Add.
The tables are displayed graphically in the new database diagram.
Hi there, How would I go about doing this question?
Give functional dependencies for the table SE(SNo,ENo,EName,City,Country) with primary key (SNo,ENo) such that
1) SE is in 1NF and not in 2NF
2) SE is in 2NF and not in 3NF
3) SE is in 3NF and not in BCNF
Explain your answers. You can use functional dependency diagrams for illustration
Would I say something like
EName -> City, Country
Eno -> EName
SNo -> ENo
Hello Everyone, I am trying to install SQL 2005 on my machine. All I want is the functionality that I enjoyed with SQL 2000- Query Analyzer and Enterprise Manager. For some reason, the version of SQL 2005 that I am installing is only giving me an option for the Configuration Manger which does not provide access to the Management Console. It is my understanding that I need the Management Console to create databases, look at tables in my databases, etc., etc. just like I did in Enterprise Manager. Is there anyone who can tell me what I'm doing wrong? Currently, the cd that I have says SQL Developer Edition. Thanks.

I am developing a web site with asp.net 2.0 and c#, using Visual Studio 2005 and Microsoft SQL Server 2005 ( I am still learning about these technologies and languages ).I transferred my web site files to my NEW computer. The web site worked fine when running inside Visual Studio, however when I tried to run it in its PUBLISHED format it was giving this error message:Server Error in '/MA' Application. Cannot open database "SiteData" requested by the login. The login failed.Login failed for user 'CENTAURUSASPNET'.I solved the problem by running SQL Server Management Stdio, right clicking “SiteData� database -> properties -> permissions->view server permissions then I chose “CENTAURUSASPNET� and since I DID NOT KNOW what grants are ESSENTIAL for the functioning of the database, I GRANTED EVERYTHING ( I ticked ALL the permissions).
But since, probably, a lot of GRANTS are not only unnecessary but also may compromise the security of the web site, I would like to know what are the ESSENTIAL OR MINIMUM GRANTS NECESSARY for making the database functional to the web site and what grants may represent a security risk.
I have a sp. I alter stored procedure by adding some logic to that. How can I test that is there any functional impact by altering that stored procedure? How to prove to the team that the modifications doesn't impact any functionality?
View 5 Replies View RelatedHi All,
Not sure if this is exactly the place to post this, but here it goes anyways.
I am writing a ASP.Net/C# program and I am interacting with a MS Access database in order to derive data on user login and logout times. Basically, I am trying to create a line graph that will display the number of users over the course of a user specified timespan. Currently, I am doing this by look at the number of users that were logged on during each minute of the timespan.
My database table setup consists of a EmployeeID column (Text), Logon Date (Date/Time), and Logoff Date (Date/Time). I have also created an index on the Logon Date and Logoff Date columns.
In order to view the number of users during a minute of the timespan I use a Jet SQL query of the following format
Code Snippet
SELECT DISTINCT Count (EmployeeID) AS [User Count]
FROM ProgramName
WHERE ([Logon Date] < #August 27, 2007 11:45:00# OR [Logon Date] Is Null) AND ([Logoff Date] > #August 27, 2007 11:45:00# OR [Logoff Date] Is Null)
The problem is that using this method I have to execute 1,440 queries for each day in the timespan. Currently this takes about 25 seconds to execute if the timespan is a full workweek (7,200 queries).
Now the question. Is it possible to create a SELECT statement that will return user counts for multiple minutes? Like maybe a SELECT statement that returns a column of counts for every minute in an hour? If it is possible, does anyone have any examples? I am hoping by lowering the number of queries my program has to execute I will also cut down the time required for the code to run.
I am pretty new to SQL, so any guidance or advice is very appreciated.
Thanks!

I had to migrate my report server (2008R2) to a new domain. I built new server and restored the old ReportServer and ReportServerTempDB into new server and also restored the certificate from old server. The Report Server is running but I don't have full access to all server futures anymore, looks like it's AD authentication messed up. My new account is Admin on new server but I can't see all options, like New Data Source, or wehn going on report level to manage to see all option such as Parameters, Subscriptions, Data Source.

I'm using SQL Server 2005 along side Visual Studio 2005, using VB to create a web application at work.
Now I'd like to bunch together some child fields in a gridview when displayed. Have a look at the attached pic to show what I would like.
Is this possible via a query or would I need to set something up on the gridview to do this?
Cheers,

I have 6 SSRS reports for account receivable module. All of these 6 reports are for one specific business requirement. The difference between these reports are layout, number of columns and styles. I want user to choose one from these 6 reports based on their requirement.
When user clicks the menu in their application to initiate the report, Is there any way that the SSRS show list of these reports in a window so that user can choose one of them?
As I am working on a 3rd party ERP application, I cannot provide a form or window in that ERP to choose one report out of these 6 reports. I believe that there is a way to do this in Crystal report, but do not know how to do this in SSRS.
i want to create bar chart dynamically. how to pass the x axis values and y axis values in crystal report in runtime.

View 2 Replies View RelatedHow can get an object's dependencies in SQL Server. For example it I have written a procedure which accesses some tables inside it then the procedure is said to be dependent on that table. Or one procedure might call another procedure and hence dependent.
Can I know an object's dependent objects from any system table. I think Oracle has a table USER_DEPENDENCIES which provides this info (I may be wrong :-().
Can anyone help ?
The previous post regarding dependencies reminded me of another bugger I comeup with from time to time. SQL Server allows us to rename objects via asystem stored procedure (I usually use an ADP front-end that presumably callsthe same procedure), but after the rename, I find singnificant strangeness.For instance, triggers are still connected to the tables, but the trigger textstill refers to the old table name. Views and stored procedures dependent onthe table are broken, and are not fixed by even by restarting the server,though I thought the cached plans were supposed to be dumped on shut-down,then recreated on demand later.Is there some tool or technique to rename a table and automatically detect andproperly drop/rebuild dependent triggers, views, stored procedures,relationships, and anything else I'm not thinking of?Oh yeah, and there are extended properties to deal with as well, but I guessthat's intractible unless we know what client build them (e.g. Access ADP),and what it expects to be recorded there, but I suppose it would be nice tojust dump them rather than leave them there possibly corrupted from a client'spersective.

I am currently using SQLCacheDependencies to help me manage my cache in an ASP.NET application that is hosted across a web farm. This utilises the SQL Server 2005 service broker feature.
I have implemented this and is currently working but i have a few questions i want to clear up and i hope someone can assist me in that.
1/. I am starting the broker service by using the command
System.Data.SqlClient.SqlDependency.Start( <connection string> );
I currently have that piece of code running when the application starts in the global.asax file.
What i want to know is will all SQL queries that hit the database register a notification?
Is is possible to only have a selected query register a notification?
In my web application only a handful of database queries require a sqlcachedependency to be created. I dont want all queries to be registering a notification as that will place a burden on my backend server.
1/. So does all queries register a notification once the broker is started?
2/. Is there a way to only tell selected queries to register a notification?
3/. When a cache object is invalidated because of a absolute and slidingscaletimeout, does the existing sqlconnection for that service broker get disposed?
Thanks

Hello,
I have a table in my SQL2000 server and there's a field in this table being created by an object - with a GREEN PLUS sign (look like an APPEND query in MsAccess). How can I locate and edit/modify that (append query-like) object within my SQL 2000 - Enterpise Manager? Here's some more details:
Table: Customer
Field1: CustomerID
Field2: CustomerRegion_ID (contains the ID above & RegionID below)
Table: Region
Field: Region_ID
--------------------------------------------------------------
When I checked on the dependencies of the table "Customer" I saw 1 dependency and this dependency has 2 table depend on it back-to-back (Customer & Region).
I want to modify the "Field2" of the "Customer" table and I looked everywhere on my VB/stored-procedure codes but couldn't find what triggle the creation of the field. The only thing that I suspect that would be the append object with "GREEN PLUS" sign. Any help would be appreciated.
Peter.
Hi
Is there any way to know as what are all the entities or objects which are dependent upon a given Table? I wanted to know if i update a particular table in a given database on a server, what are all the other tablesobjects which gets effected because of this updation, may be because of some update triggers defined on this tabl or through cascading updates etc. Any system stored procedure which can help me to know these dependencies.
Many Thanks in Advance!
Hello Everyone,
I want to run the SSIS service on a few computers. Can I "only" install this service or does this service needs an instance of the SQL server database as well?
* If it does need the database, can the database be shared between various instances of the service or does each one of them need their own database instance?
* are there any particular databases which are needed by SSIS in order to execute? like master, msdb or tempdb?
regards,
Abhishek.
Hey!
I am creating a kind of file browser for an application of mine. The principle is quite straight forward. It consists of folders and files. Each folder can contain other folders and files and so on. The twitch however is that i need a special root entity called site. The site is very much alike a folder but has some other properties. The site can contain folders and files.
To achieve this ive created te following tables (truncated for clearity):
#################### Sites ##################### ID [Int] ## ... ####################
#################### Folders ##################### ID [Int] ## SiteID [Int] ## FolderID [Int] ## ... ####################
#################### Files ##################### ID [Int] ## SiteID [Int] ## FolderID [Int] ## ... ####################
Both the folder table and the files table have a check constraint that ensures that either SiteID or FolderID is NULL. They WILL be part of EITHER a folder or a site. Not both!
Then i set up the foreign constraints as follows:Folders.FolderD -> Folders.IDFolders.SiteID -> Sites.IDFiles.FolderID -> Folders.IDFiles.SiteID -> Sites.ID
All constraints have cascade on delete and therefore the last of them cannot be created as it would be circular. (Wich it wont in this case, but theoreticaly its possible)
Iknow WHY this is rendering an error. But how can i work around it? Or would you suggest another design of the tables?
