I have VS 2005 and SQL Server 2005 Express installed and I created 4 tables and setup the primary and foreign keys and can view the individual foreign key relationships by right clicking on the foreign key.
Is there a way to view a table relationship diagram (fields with primary and foreign keys), such as Access provides. Does VS 2005 or SQL Server 2005 have that capability?
Thanks

Polato Student Record System
"The Polato university administration has decided to computerise their student record system. The system must be able to automatically print a new ID card for students on their admission and after completion of each academic year. The card should have the student’s name, number of years and the message welcome to 1st, 2nd or final year.
In a bid to curb the rate of incompletion, the system should also be able to record attendance of students to any class. The system should be able to automatically send out a warning to any student that misses any two lectures for the first time. (Of course the student should come up with a very good reason for missing the lectures or else he/she will be removed from the module). Missing three or more lectures leads to automatic withdrawal from the module involved. A student will receive notice from the system, right after missing the second lecture.
The system also must be able to calculate each student’s results for that semester only showing details of all modules taken. You should use the simple formula; the total of all the modules taken, divided by the number of modules"

How can I create a one-to-one relationship in a SQL Server Management Studio Express Relationship diagram?
For example:
I have 2 tables, tbl1 and tbl2.
tbl1 has the following columns:
id {uniqueidentifier} as PK
name {nvarchar(50)}
tbl2 has the following columns:
id {uniqueidentifier} as PK
name {nvarchar(50)}
tbl1_id {uniqueidentifier} as FK linked to tbl1.id
If I drag and drop the tbl1.id column to tbl2 I end up with a one-to-many relationship. How do I create a one-to-one relationship instead?

I need to design a schema that will provide me a hierarchical view in reporting. I mean by this is, lets say:
Hospital
|_________> Hospital Entity
| | |
| | V
| | Clinic A
| | - Jane Doe MD
| | - Janette Brown MD
| | ACME Clinic
| | - Jennifer Smith MD
| | Clinic of Jennifer Smith MD
| | - Jennifer Smith MD
| | - Billy Johnson MD
| |
| V
| - Earl Brown MD (Hospital Entity Resident Practitioner)
| - Janette Brown MD
V
- John Smith MD
- Bob Jones MD
The design should also allow me to query a practitioner and the query will show all the entities he or she is a member of.
If this is not the correct place to post this posting, please let me know the correct place and I will make the necessary changes.
Thanks,

Hi there, I just set up my AppData and i'm trying to connect the Membership to a tbl_Profile that i created.I notice there's an application_id and a user_id which are uniqueidentifiers. I've been trying create a relationship to tbl_Profile's user_id column but it won't let me saying it's not compatible. Am i suppose to set tbl_Profile's user_id column to int or uniqueidentifier? I've tried both and it won't let me... THanks!

I am trying to create an opportunity report that includes notes from the notes entity. Unfortunatly, when I pull the fields from the notes entity into my reports, it seems there is no way to tie the notes to specific opportunities or accounts that they are associated with and I get all notes under the first item listed on my report. Is there a way to link data sets like Access lets you link tables?
View 3 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.
I have four tables with relationships as shown. They have a circular relationship and so one of the relationships is forced to be inactive.
Operation (Commodity, OperationKey) ==========>
Commodity (Commodity)
/
/
|
|
Advice (OperationKey) ====== (inactive)=======>
Operation Commmodity (Commodity, OperationKey)
I have the following measure:
Advice No. Commodity:=CALCULATE (
COUNTROWS ( 'Advice' ),
USERELATIONSHIP(Advice[OperationKey],'Operation Commodity'[OperationKey]),
operation
)
However, the userelationship function does not override the active relationship between Operation & Advice and so the measure is limited to Advices directly filtered by the Operation table.
If I delete the relationship between Operation and Advice, then the measure works as expected i.e. Operation indirectly filters Operation Commodity which filters Advice.

Hi,
I have a table called Posts which contains an attribute Hospital ID. This is a foreign Key to the Hospitals table, which contains two fields : Name & Region.
In my report model, I would like the Hospital ID to be replaced with just the Hospital name. I have set the Hospitals entity to IsLookup=True and the IdentifyingAttribute to Hospital ID. However, in the report builder Hospital ID is still being displayed with no sign of the hospital name.
Can anyone point out where I'm going wrong? I have tried setting the Name field in Hospitals to Role or Merge as I read that using 'name' might cause some problems but that made no difference
Hello to everyone!
I would like to ask you sthg as far as the e-r model is concerned!
I haven't started of course to use SQL yet,cause i have to make the e-r model first.
I have a a question to make :
For example i have to keep data for a Personal Computer (PC)
So i have the entity : COMPUTER
COMPUTER has many characteristics/fields like the primary key which is going to be PC_ID and it's unique for every computer,NAME_OF_PC the name and also TYPE_OF_MOTHERBOARD, TYPE_OF_RAM, TYPE_OF_HARD_DISK etc.
I have to keep for the TYPE_OF_MOTHERBOARD the manufacturer, the motherboard's code etc.
Shall i make an entity for the motherboard or for the HARD_DISK or for the RAM?
Cause i want next to change these fields of every COMPUTER if it's n eeded!
e.g. i have the PC_ID = 12 and i want to change the hard disk cause it's not working!(shall i keep an entity of the hard disk or not?)
Can sm advise me what i shall do?
Thanks, in advance! :)

Hi,
I'm trying to find out whether it is possible to integrate an external entity into MS SQL Server in following way:
the entity defines certain set of tables
when user performs a query on one of these tables, the query is sent to the entity for processing and results are returned back to SQL server (and to client)
I thought integration services could be used for this task, but I'm quite unfamiliar with MS SQL server, so I don't know whether it would be a feasible solution...
Hello SQLers,
I`m looking for logical database entity relation diagram builder tools. Anyone have any suggestion or links?
TIA.
Working in a project using Entity Framework (Code First)...
Until now the project has been connected to a (generated) SQL Server Compact 4.0 database,
but now we want to connect to a SQL Server (at least 2008R2 since we will use FILESTREAM...)
Our problem right now is the possibility to enter Infinity values into REAL columns in the DB...
It works in the SQL Server Compact but we have not been able to get it to work in 2008R2 or 2014
The insertion of Infinity values is constructed by the Entity Framework (from using float.PositiveInfinity in C#) automatically so I mainly wonder if it at all is possible in a "real" database. Maybe there are some configurations possible to get it to work?
Is it possible to set an entity is update but can't add/delete? I want to control adding/deleting members in SSIS from another source system, but only allow users to change certain attributes.

I've got 2 entities "Agent" and "Function".
"Agent" has a code, a name, and an attribute called "function_code" which refers to "Function"'s code
"Function" as a code and a name. Name is the description of the function.
I'd like to see in a single row :
"Code", "Name", "Funcion_code" and "Name" (the last one from the entity "Function").
In SQL it will something like
Select a.code, a.name, a.function_code, f.name
from agent a, function f
where a.function_code = f.code
I've tried with explicit hierarchy, derived hierarchy, consolidated members...
I was able to have an entity with all those attributes but I can choose the attribute I want. My goal is that, according to "Function_code" in Agent, I get the "Name" of the function...
I have a datagridview bound to a table that is part of an Entity Framework model. A user can edit data in the datagridview and save the changes back to SQL. But, there is a stored procedure that can also change the data, in SQL, not in the datagridview. When I try to "refresh" the datagridview the linq query always returned the older cached data. Here's the code that I have tried using to force EF to pull retrieve new data:
// now refresh the maintenance datagridview data source
using (var context = new spdwEntities())
{
var maintData =
from o in spdwContext.MR_EquipmentCheck
where o.ProdDate == editDate
orderby o.Caster, o.Strand
select o;
mnt_DGV.DataSource = maintData;
}
When I debug, I can see that the SQL table has the updated data in it, but when this snippet of code runs, maintData has the old data in it.
I was able to view the MDS entity through web interface. But now when i click on web interface I am not able to view it from internet explorer and Mozilla firefox.

I have an entity (A), in which I use domain based attribute. The second entity (B) has several attributes. My problem is that, I would like to filter the first entity (A) based on an attribute that belongs to the second entity. The only way I can filter it (in MDS Excel add-in or Explorer) is by using Code or Name from the second entity.
I have in mind a couple of solutions, but they require some coding with xml saved query from Excel.
