Hi Guys,
Is it better to create all tables (in store procedure) and then another store procedure to create and apply all relationship between the tables??? , OR
is it better to have each table relationship at the end of the store procedure to create that table and have each table relationship at the end of its create statement???
What are the Advantages and disadvantages of each method?
Thanks,
Mehdi
Hi,
I'm faced with a dilemma regarding db design. I would like to have a generic table that links to many tables, but somehow still enforce integrity with a constraint.
Eg An ownership table, then various document tables eg Loan document table, budget document table. Both the load table and budget table are linked to the ownership table by their primary keys.
Ownership will have doc_id and doc_type columns. How do I enforce integrity ie the load_id = doc_id where doc_type = 'LOAN' and budget_id = doc_id where doc_type = 'BUDGET' are valid using a contraint? I believe check contraints cannot span across tables, is there a work around?
I know a simple solution would be to use separate ownership tables, but I would like to make it generic.
Many Thanks
Paul
Hello
I have a problem with setting relations properly when inserting data using adonet. Already have searched for a solutions, still not finding a mistake...
Here's the sql management studio diagram :
and here goes the code1 DataSet ds = new DataSet();
2
3 SqlDataAdapter myCommand1 = new SqlDataAdapter("select * from SurveyTemplate", myConnection);
4 SqlCommandBuilder cb = new SqlCommandBuilder(myCommand1);
5 myCommand1.FillSchema(ds, SchemaType.Source);
6 DataTable pTable = ds.Tables["Table"];
7 pTable.TableName = "SurveyTemplate";
8 myCommand1.InsertCommand = cb.GetInsertCommand();
9 myCommand1.InsertCommand.Connection = myConnection;
10
11 SqlDataAdapter myCommand2 = new SqlDataAdapter("select * from Question", myConnection);
12 cb = new SqlCommandBuilder(myCommand2);
13 myCommand2.FillSchema(ds, SchemaType.Source);
14 pTable = ds.Tables["Table"];
15 pTable.TableName = "Question";

26
27 ds.Relations.Add(new DataRelation("FK_Question_SurveyTemplate", ds.Tables["SurveyTemplate"].Columns["id"], ds.Tables["Question"].Columns["surveyTemplateID"]));
28 ds.Relations.Add(new DataRelation("FK_Possible_Answer_Question", ds.Tables["Question"].Columns["id"], ds.Tables["Possible_Answer"].Columns["questionID"]));

67 myCommand2.Update(ds, "Question");
68 myCommand3.Update(ds, "Possible_Answer");
69 ds.AcceptChanges();

and that causes (at line 67):"The INSERT statement conflicted with the FOREIGN KEY constraint

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 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)  ==========>Â
Commodity (Commodity)
                     /                                                                       Â
/
                      |                                                                        Â
|
  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, all.
I am trying to create table with following SQL script:
Code Snippet
create table Projects(
ID smallint identity (0, 1) constraint PK_Projects primary key,
Name nvarchar (255) constraint NN_Prj_Name not null,
Creator nvarchar (255),
CreateDate datetime
);
When I execute this script I get following error message:
Error source: SQL Server Compact ADO.NET Data Provider
Error message: Named Constraint is not supported for this type of constraint. [ Constraint Name = NN_Prj_Name ]
I looked in the SQL Server Books Online and saw following:
CREATE TABLE (SQL Server Compact)
...
< column_constraint > ::= [ CONSTRAINT constraint_name ] { [ NULL | NOT NULL ] | [ PRIMARY KEY | UNIQUE ] | REFERENCES ref_table [ ( ref_column ) ] [ ON DELETE { CASCADE | NO ACTION } ] [ ON UPDATE { CASCADE | NO ACTION } ]
As I understand according to documentation named constraints should be supported, however error message says opposite. I can rephrase SQL script by removing named constraint.
Code Snippet
create table Projects(
ID smallint identity (0, 1) constraint PK_Projects primary key,
Name nvarchar (255) not null,
Creator nvarchar (255),
CreateDate datetime
);
This script executes correctly, however I want named constraints and this does not satisfy me.
We are using SQL CE 3.5 on tablet PCs, that synchs with our host SQL 2005 Server using Microsoft Synchronization Services. On the tablets, when inserting a record, we get the following error:
A duplicate value cannot be inserted into a unique index. [ Table name = refRegTitle,Constraint name = PK_refRegTitle
But the only PK on this table is RegTitleID.
The table structure is:
[RegTitleID] [int] IDENTITY(1,1) NOT NULL,
[RegTitleNumber] [int] NOT NULL,
[RegTitleDescription] [varchar](200) NOT NULL,
[FacilityTypeID] [int] NOT NULL,
[Active] [bit] NOT NULL,
The problem occurs when a Title Number is inserted and a record with that number already exists. There is no unique constraint on Title Number.
Has anyone else experienced this?
This is probably a simple task but I just don't know how to do it. I need to return a recordset of details with a row of totals for selected columns. Something with a result like this:
Location Attendance Showings
======== ========== ========
JOHNS 210 3
SEREN 116 2
total 326 5
I know I could do this with a stored procedure, but I'd prefer to do it with just one sql statement. I tried compute but because I have a total on more than one column, the returned recordset is actually 3 rows.
Thanks in advance for any suggestions.
Hi everyone,
Is there a way in SQL to include and execute another file? For example, I have file1 and I would like to execute the contents of file2 from file1. How can this be done?
Thanks!
Need to find a way to do this. I have two tables, One with codes i.e. S,R,T and other with transactions looks like this:
Transaction table
Emp Trans Tot...
X55677 S 8
X55677 R 2
C22887 S 4
C22887 T 3
F66889 S 9
F66889 R 4
F66889 T 3
Code table
S
R
T
Not sure if the code table even helps. What I want to do is show all three transactions for each employee even if they don't have any (would be zero) like so...
Emp Trans Tot...
X55677 S 8
X55677 R 2
X55677 T 0
C22887 S 4
C22887 T 3
C22887 R 0
F66889 S 9
F66889 R 4
F66889 T 3
How can I get to this. I'm sure there must be a solution already posted for something like this but I'm not sure what to search for.
Thanks for your thoughts.

Hi, I have the following query stored:
SELECT dbo.OrderDetails_Retail.ProductID, dbo.OrderDetails_Retail.ProductName, SUM(dbo.OrderDetails_Retail.Quantity) AS ProdQtyPerWeek, DATEPART(wk,
dbo.Orders_Retail.OrderDate) AS SalesWeek, YEAR(dbo.Orders_Retail.OrderDate) AS SalesYear
FROM dbo.OrderDetails_Retail INNER JOIN
dbo.Orders_Retail ON dbo.OrderDetails_Retail.OrderID = dbo.Orders_Retail.OrderID
WHERE (dbo.Orders_Retail.account = @Account) AND (dbo.Orders_Retail.OrderStatus <> 'Deleted') AND (dbo.Orders_Retail.PayStatus <> 'Pending') AND
(dbo.Orders_Retail.OrderStatus <> 'Refunded') AND (DATEDIFF(d, dbo.Orders_Retail.OrderDate, @StartDate) <= 0) AND (DATEDIFF(d,
dbo.Orders_Retail.OrderDate, @EndDate) >= 0)
GROUP BY YEAR(dbo.Orders_Retail.OrderDate), DATEPART(wk, dbo.Orders_Retail.OrderDate), dbo.OrderDetails_Retail.ProductID,
dbo.OrderDetails_Retail.ProductName
ORDER BY dbo.OrderDetails_Retail.ProductID, dbo.OrderDetails_Retail.ProductName, YEAR(dbo.Orders_Retail.OrderDate), DATEPART(wk,
dbo.Orders_Retail.OrderDate)
Basically, it will return a load of results grouped by product for how much qty of that product was sold per week during a date range...
As my client wants to select multiple products at once to compare rather than do it in my application (I'm building something in ASP), I thought I might be able to do it on the database side.
The problem with the above is that.. lets say I select a date range that has weeks 1-4 in it.
Product 1 only sold qty's for weeks 1-2, product 2 sold for only week 3 and product 4 sold in all four weeks.
I'd get
Prod | Qty | Week
1 23 1
1 12 2
2 10 3
3 22 1
3 15 2
3 12 3
3 4 4
Although this looks fine - what I actually need is:
1 23 1
1 12 2
1 0 3
1 0 3
2 0 1
2 0 2
2 10 3
2 0 4
3 22 1
3 15 2
3 12 3
3 4 4
Does that make sense?
Any ideas on how to do this?
We today have 3 different indexes on a table that look like this

CREATE INDEX IX_02 ON TORDLOG ([REGDAT]) INCLUDE ([ORDENR], [SUBNRX], [KUNDNR], [ALFKOD], [SUMMSP], [SUMMPP], [SUMMBP])
CREATE INDEX IX_03 ON [TORDLOG] ([REGDAT]) INCLUDE ([ORDENR], [SUBNRX], [RADNRX], [KUNDNR], [ALFKOD], [SUMMSP], [SUMMPP], [SUMMBP])
I want to combine the index to only 1 index; How do can combine all the include columns to one large? Or shall keep all index. Bit bad on how to handle include columns. Or just create new index with regdat and forget all about include?
CREATE INDEX IX_02 ON TORDLOG ([REGDAT])
OR
CREATE INDEX IX_02 ON TORDLOG ([REGDAT]) INCLUDE (ALL COLUMNS)
Hi:I have an application in which I am producing a lists of media outlets based on a number of 6 possible parameters including location, medium, format, scope, language and coverage. I have an interface in which users can select some or all of the possible parameters. Where they don't choose a parameter - e.g. location, I would like the SELECT query to include all locations. I am at the point now of writing 6 X 6 = 36 possible queries to handle the different combinations of possible parameters. This seems a bit excessive and clumsy. I am just learning about stored procedures and was wondering if it is possible to create a procedure that would accept the 6 parameters including ones with null or 0 values and generate a query that would ignore those that were null or zero. Any help in this regard greatly appreciated.Roger Swetnam

I have a table of parts and want to display some statistics from it. The parts table has several fields in it, but the two that I need to use in my sql select queries are "PartUserID" and "DateUseBy", but I don't know how to use the "dateuseby" in the second example.Can someone help me out with #2?1.

I've got a query where i need to return a max value based on a select but one of the fields i need to return in the results is the records primary key ID No. This messes up the MAX bit and means that all results are returned, not just the max one.
The query i'm using is very long so i've simplified what i mean by the example below. Say i have a table 'Fruits':
ID FruitName Cost1 Apple 0.452 Apple 0.633 Apple 0.524 Pear 0.895 Pear 0.83
And run the query:
select max(Cost),FruitName From Fruitsgroup by FruitName
It'll correctly return:
FruitName CostApple 0.63Pear 0.89
Now i need the ID also returned by my query so i go:
select max(Cost),FruitName,ID From Fruitsgroup by FruitName,ID
This doesnt return the above results with the ID appended to it, it instead returns:
ID FruitName Cost1 Apple 0.452 Apple 0.633 Apple 0.524 Pear 0.895 Pear 0.83
As the ID is always distinct and therefore messes up the grouping. How in this instance would i return the correct result of:
ID FruitName Cost2 Apple 0.634 Pear 0.89
Thanks.
