When we have Table1 and Table2, then we
link both tables using a third table Table3 that relates n records in
Table1 to n records in table2, how do we call Table3? There is a name
in dataBase modeling for that, right?
I'm getting this warning each time I auto-generate my model. I'm using named queries with logical primary keys.
The relation property of the role "xxx" refers to the target end of relation "xxx" which is not bound to a set of uniquely contrained columns.
I've searched and can't figured out what I am being warned about and whether I need to fix something. Can you help?
Thanks,

If i add a new table to my database with a stored procedure, using that same sp or another can i also add a 1-M relationship with another table that is currently in the database. Please if you can provide an example.
Thank you,
Hi,
I am new to sql and is working with sql server managment 2005 +c# 2005.
My application needs to create a blockdiagram sort of thing say
if in my database i got a table 'Addition' with 'a', 'b', 'c',and the primary key addition_id, and c is related to a and b as c = a+ b.
there is stored procedure name usp_addition which contains this relation. Each time any insert or update is done this sp is executed and all the values are updated for accordingly.
My problem starts in the front end where i need to draw the graphical representation of table addition.
In this graphical representation, I need to draw the labels a, b, c and the arrows from a and b which will connect to c, showing that c has a, b as inputs.
I got the label using dataset and datacolumns but hte problem is how to create the arrows the name of labels (i.e my column names from which the arrow should start and end)
How does I get the information that c as two inputs a, b. I dont need the values since i just want to view the columns in table and which column is input to another column.
Since I need to do this dynamically because my tablename, and the number and name of column would differ does any body knows how to do this.

I'm a bit new to SQL, so this might be a very simple question, but I was not able to find an answer by search:
I got two tables, with a 1:n relation between them, seller and article, and I want to delete all sellers that do not offer any articles anymore.
An extract of my SQL to show the tables and the relation:
@"CREATE TABLE dbo.[Seller]
(
[ID] uniqueidentifier NOT NULL ROWGUIDCOL CONSTRAINT [PK_Seller] PRIMARY KEY,
) ON [PRIMARY]",
@"CREATE TABLE dbo.[Article]
(
[ID] uniqueidentifier NOT NULL ROWGUIDCOL CONSTRAINT [PK_Article] PRIMARY KEY,
[SellerID] uniqueidentifier NOT NULL,
) ON [PRIMARY]",
@"ALTER TABLE dbo.[Article] ADD CONSTRAINT [FK_ArticleSeller] FOREIGN KEY
(
[SellerID]
) REFERENCES dbo.[Seller]
(
[ID]
)",
Now say I got two sellers (1 & 2), and only one article (1, offered by seller 1). The delete query should delete seller 2 because he is not offering articles anymore.
This probably is dead simple in SQL, something like
DELETE FROM seller WHERE COUNT(article.SellerID=seller.ID)==0
but honestly, my SQL books leave me guessing here, and I found no online ref for cases like this.
Maybe someone can help me here?
Thanks in advance,
Sam
I have 2 tables in a 1: n relation. How can i get a select statement that the field in the n-relation with outputs, separated by a semicolon; Example: One person have many Job Titles

I want to build Parent child relation . i have two aproaches .I would like to know which is the best solution ?
1)1st method:-
Parent table with parent id . Child table with child id and parent id.Foreign key relationship exists between parent and child tables with cascade delete option enabled.
Parent TAble
Id name
1 XYZ
Child table
id name parent id
1 abc 1
2 qwe 1
2)2nd method
table with id and parent ID. Top level element will have null value in table. eg
id name parent id
1 xyz
2 abc 1
3 qwe 2
4 adf 1
Retrieve data using recursive queries supported in SQL Express.
Which is the best solution to store parent child relationship???

I have 2 tables:
TableA:
Name
UserA
UserB
UserC
Table B:
Name Data
UserA xxx
UserB asdasd
UserB ewrsad
UserC dsafasc
UserA sdf
UserB dfvr4
I want to count the total entries in Table B for every user in Table A. The output would be:
Name Count
UserA 2
UserB 3
UserC 1
I can use a Select Count statement, but I will have to make a SQL call for every user in Table A. Also, Table A is dynamic, so the users are always changing. Can this be incorporated into one SQL call to count the total rows in Table B for each user in Table A?

Hi,
I am producing a php report using SQL queries to show the SLA status of our calls. Each call has response, fix & completion targets. If any of these targets are breached, the whole SLA status is set as 'Breach'.
The results table should look like the one below:
CallRef.
Description
Severity
ProblemRef
Logged
Date
Call
Status
SLA Status
C0001
Approval for PO€™s not received

C0003
Approval for PO€™s not received from Siebel.

n/a
05-01-06 14:48
Investigating

Whereas I can pick the results for the first 6 columns from my Select query, the 'SLA Status' column requires the following calculation:
if (due_date < completed_date)
{ sla_status = 'OK';
}
else sla_status = 'Breach';
The Select statement in my query is looking like this...
Select Distinct CallRef, Description, Severity, ProblemRef, Logdate, Status, Due_date, Completed_date;
The problem is that my query is returning multiple entries for each stage of the call (see below), whereas I just want one entry for each call, with SLA status 'Breach' if any of the stages for the call were out of SLA.

Any help will be much much appreciated, this issue has been bothering me for some time now!!!
Good day!
What is the syntax on calling a function from a column formula in an MS SQL table.
I created a table, one column's value will be coming from a function. And at the same time, I will pass parameters to the function. How do I do this? Is this correct?
SELECT dbo.FunctionName([Parameter1, Parameter2])
But i can't save the table, "Error validating the formula".
Pls. help
Thanks a lot.
I have a stored proc that inserts into a table variable (@ReturnTable) and then ends with "select * from @ReturnTable."
It executes as expected in Query Analyzer but when I call it from an ADO connection the recordset returned is closed. All the documentation that I have found suggests that table variables can be used this way. Am I doing somthing wrong?
I'm trying to do something like this:
Loop through #Temp_1
-Execute Sproc_ABC passing in #Temp_1.Field_TUV as parameter
-Store result set of Sproc_ABC into #Temp_2
-Update #Temp_1 SET #Temp_1.Field_XYZ= #Temp_2.Field_XYZ
End Loop
It appears scary from a performance standpoint, but I'm not sure there's a way around it. I have little experience with loops and cursors in SQL. What would such code look like? And is there a preferable way (assuming I have to call Sproc_ABC using Field_TUV to get the new value for Field_XYZ?
The first query returns me the results from multiple databases, thesecond does the same thing except it puts the result into a #temptable? Could someone please show me an example of this using the firstquery? The first query uses the @exec_context and I am having achallenge trying to figure out how to make the call from within adifferent context and still insert into a #temp table.DECLARE @exec_context varchar(30)declare @sql nvarchar(4000)DECLARE @DBNAME nvarchar(50)DECLARE companies_cursor CURSOR FORSELECT DBNAMEFROM DBINFOWHERE DBNAME NOT IN ('master', 'tempdb', 'msdb', 'model')ORDER BY DBNAMEOPEN companies_cursorFETCH NEXT FROM companies_cursor INTO @DBNAMEWHILE @@FETCH_STATUS = 0BEGINset @exec_context = @DBNAME + '.dbo.sp_executesql 'set @sql = N'select top 10 * from products'exec @exec_context @sqlFETCH NEXT FROM companies_cursor INTO @DBNAMEENDCLOSE companies_cursorDEALLOCATE companies_cursor-------------------------------------------------------------------------------------CREATE TABLE #Test (field list here)declare @sql nvarchar(4000)DECLARE @DBNAME nvarchar(50)DECLARE companies_cursor CURSOR FORSELECT NAMEFROM sysdatabasesWHERE OBJECT_ID(Name+'.dbo.products') IS NOT NULLORDER BY NAMEOPEN companies_cursorFETCH NEXT FROM companies_cursor INTO @DBNAMEWHILE @@FETCH_STATUS = 0BEGINset @sql = N'select top 10 * from '+@DBNAME+'.dbo.products'INSERT INTO #Testexec (@sql)FETCH NEXT FROM companies_cursor INTO @DBNAMEENDCLOSE companies_cursorDEALLOCATE companies_cursorSELECT * from #TestDROP TABLE #Test

How to call a table valued functions from SSRS reports ?Â
Is there a way to call by selecting Dataset properties> Query >Stored Procedure radio button, If not then why our object type function is visible under this list.
MS SQL Server 2008 R2
I have a situation where I need to call a stored procedure once per each row of table (with some of the columns of each row was its parameters). I was wondering how I can do this without having to use cursors.
Here are my simulated procs...
Main Stored Procedure: This will be called once per each row of some table.
-- All this proc does is, prints out the list of parameters that are passed to it.
CREATE PROCEDURE dbo.MyMainStoredProc (
@IDINT,
@NameVARCHAR (200),
@SessionIDINT
)
AS
BEGIN
[Code] ....
Here is a sample call to the out proc...
EXEC dbo.MyOuterStoredProc @SessionID = 123
In my code above for "MyOuterStoredProc", I managed to avoid using cursors and was able to frame a string that contains myltiple EXEC statements. At the end of the proc, I am using sp_executesql to run this string (of multipl sp calls). However, it has a limitation in terms of string length for NVARCHAR. Besides, I am not very sure if this is an efficient way...just managed to hack something to make it work.

I have two tables
tNames which contains 'ID' and 'Name'
tLocations which contains 'ID' and 'Location'
each ID may be associated with many Locations
I want to run a query to display these results:
[ID, Name, Location]
but only to return the first Location associated with that ID (or the max, min, I don't really care as long as it's only one result)
right now I have
Code:
SELECT tNames.ID, tNames.Name, tLocation.Location
FROM tNames INNER JOIN tLocations
ON tNames.ID = tLocations.ID
but this returns a new row for each different Location of the same ID
Thanks.

Hello,I'm relative new to sql and databases and the last few weeks I learnedmyself a lot. I'm trying to make a hotel reservation application.I have a database with a table Booking, a table Room, a tableRoomsPerBooking. So a booking contains date/time etc and a fieldRoomsPerBookingID. The table RoomsPerBooking contains number ofpersons, unitprice etc. and a field ID and a field RoomID. The tableRoom contains data like name, notes etc.now i have two questions:First about relations:The table Booking has relationship: PK table RoomsPerBooking - ID <-->FK table Booking - RoomsPerBookingID.The table RoomsPerBookingID has relationship: PK table Room - ID <-->FK table RoomsPerBooking - RoomIDIs this relationset good for my purpose? I think it is, but I am notsure.The second question is:How do I get available rooms per nightI came this far.... what are the "some statements"?CREATE PROCEDURE dbo.GetAvailableRooms(@BeginDate DATETIME,@EndDate DATETIME)ASSELECT Room.*FROM RoomWHERE Room.ID NOT IN (SELECT DISTINCT room.IDFROM Room room JOIN RoomsPerBooking roomsPerBookingON room.ID = roomsPerBooking.RoomID--Some statements--WHERE booking.FromDate <= @EndDateAND booking.ToDate >= @BeginDate)GO
