Failing To Make Relationship Between To Tables Of SQL Server DB

Apr 27, 2004

Hi,





I'm trying to make relationship between two tables "reservation" and "charges". The column is "booking_ticket". Its giving me following error :








'reservations (akr)' table saved successfully


'charges (akr)' table


- Unable to create relationship 'FK_charges_reservations'.


ODBC error: [Microsoft][ODBC SQL Server Driver][SQL Server]ALTER TABLE statement conflicted with COLUMN FOREIGN KEY constraint 'FK_charges_reservations'. The conflict occurred in database 'limp', table 'reservations', column 'booking_ticket'.








I used to make relationship before , but never found this problem.








Kindly guide me to solve it.





Regards,

Retrieving The Tables Relationship From SQL Server Database Diagrams

May 26, 2004

Hi All,

Currently i am defining a simple relationship between
Customers->Orders->Order Details through the Database Diagrams feature in
the SQL 2K. Using the Server Explorer, i can see the Database Diagrams, but
when i try to "drop" the Database Diagrams into the page, it gives the error
message.

I would like to know the procedures to retrieve the database relationships
from Database Diagrams and manipulate them through ADO.NET

I prefer to "convert" already defined relationship using SQL Server Database
Diagrams into XSD file or probably there is another method to "read" those
relationship and manipulate them.

Thank you very much for all your help

How Can I Create A One-to-one Relationship In A SQL Server Management Studio Express Relationship Diagram?

Mar 25, 2006

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?

Combing Two Tables With No Relationship

May 8, 2007

Which way to go?
Have two separate programs(Visual Studio-Coded in Visual Basic) that share the same sql 2005 database(called Night Audit)
The tables are called RoomSettlement and Settlement.
They were separate tables and separate programs in the past because it was just exported in excel to a visual integrator that dumped the amounts into our accounting software.


Now needing to combine the two tables(that have no link) on to a single excel sheet daily where the tables have the same date:
Table: Room Settlement – Field: RoomSettlementDatetxt =
Table: Settlement – Field: SettlementDatetxt


Any Ideas on the best way to go? (Link the tables with a foreign key and primary key, maybe union based on date, or any easier suggestion with out having to change a lot of the program )

How To Create A Datagrid For Two No Relationship Tables

Jan 13, 2004

Hi, I am trying to create a create for two table A and table B which have no relationship each time. For TableA, there are 3 columns like ID, APoints1, APoint2. For Table B, there are also 3 columns as ID, Qty, BPoints. There is no internal relationship for these two tables. But there may be same ID inside A and B for some records. Now I want to create a datagrid for displaying the information as :

ID, Sum(A.APoints1 + A.APoints2) - Sum(B.Qty * B.BPoints) WHERE A.ID = B.ID

Please Notice that I can't use directly SQL script as following from table A and table B because there is no relationship for Table A and Table B, otherwise the recult set would be wrong:

Select A.ID, Sum(A.APoints1 + A.APoints2) - Sum(B.Qty * B.BPoints) WHERE A.ID = B.ID group by A.ID


May I know is there solution for it?

Thank you very much!

Page 3 - Multiple Tables Without Relationship

Mar 20, 2007

Inner join vs outer join:

Inner join will remove rows from the first table if there is not a corresponding row in the 2nd table. Outer join will keep the rows, and use all NULL values to fill in the gaps in the 2nd table.

In general outer joins are more likely to grow a result set and inner joins are more likely to shrink one (though that will depend on the data and the query). For this reason, it is usually better when building complex queries to try to do your inner joins before your outer joins, because then you will keep your result set smaller for longer and thus the later joins can run faster.

Help With INSERT Multiple Tables In Many-to-many Relationship?

Feb 2, 2006

I am relatively new to MS SQL (not a novice, but hardly a master).

I am working on a content management application for a magazine publisher. It’s written in ASP (VB Script) and being created on Dreamweaver 8 with an MS SQL 2000 database. Now, I’m trying to decide the best and fastest approach to coding a complex INSERT and UPDATE function. My question isn’t as much about the SQL (although that will probably come up after I decide how to do this), but about the procedural steps and approach I shuold be taking to do this.

Reporters will use an online form to enter their story into the system. It collects the usual data: Headline, byline, story content, and the story category (feature, opinion, entertainment, business, sports, etc.). Each story may belong to MULTIPLE categories (feature & business, for example).

So, I’ve created three tables to support this many-to-many realtionship:

Story
Category
StoryCat (a junction table with the IDs from both the other tables).

The online form has a dropdown menu which pulls the available categories from the Categories table. When the reporter has entered the data I use ASP to performs the insert just as you would expect it to.

The next step needs to be to update the StoryCat table so that it creates a new record with the StoryID of the record it just inserted, along with the CategoryID that was in that record.

------------------

As I said, I’m not sure of the best way to do this.

Should I just pull back the last record inserted and then create a procedure that would insert into the StoryCat table (which is what I’m thinking of doing on the confirmation page), or is there another approach I should take (perhaps some sort of temporary table or stored procedure?).

Any and all help will be greatly appreciated.

Jun 11, 2007

Hi!

It's been always said that it is best to put index on commonly joined fields in the table. But putting too much index on the table would cause the table to be slow on insert and update.

My question is, how do you deal with your fields that uses look up tables? Like for example for these fields

- CountryID(smallint)
- CreatedBy(int)
- ModifiedBy(int)
- Status(tinyint)

Those fields don't come a big part in the table, though when I query the table I always join them with their respective primary table to get their respective text value. Do I still need to put Index & FK relationships to these fields?

What fields are normally good candidates for index or fk relationships?

Thanks,
Enzo

Relationship Between Inserted And Deleted Tables?

Jul 30, 2007

Hi all,

I just ran across an issue on a SQL 2000 sp4 db where RI was being maintained solely with triggers. I am attempting to change the primary key of a parent table and cascade the results to all its children without using the vendor-supplied trigger code (long story...) using an INSTEAD OF trigger.

My question is: does SQL Server create any kind of relationship between the inserted and deleted tables that I could exploit since the key field is unavailable?

I am trying to avoid having to add a surrogate key to each of the children just for this activity (as there are many M rows in each and no other suitable unique column combinations that span all the child tables).

Power Pivot :: Multiple Relationship Between Same Tables

Sep 8, 2015

I am developing a database in PowerPivot and I am wondering how to create many relationships between the same 2 tables. All relationships must be active.

Let me give you a DUMMY example: let's say that the database has 2 tables, the Employee table and Manager table:

->Employee Table: Employee_name, Previous_Manager, Current_Manager
->Manager Table: Manager_Name

Because I have 2 manager fields in the employee table, I need to create 2 links between the employee and manager tables:

-> Link 1: Previous_Manager ---- Manager_Name
-> Link 2: Current_Manager ---- Manager_Name

Right now, one of the links is inactive...

Is there a way in PowerPivot to create 2 active links like that ?

I have Power Pivot version 11.0.3000.0 on Excel 2010 on Windows 7

SSIS And Parent-Child Relationship Tables

Jun 15, 2006

Supose I have two records in a parent-child relationsuip (actually I have many more such records). Does SSIS offer any support ask for inserting one record into the parent table, the other into the child table, and updating the foreign key of the child to point to the parent?

TIA,

Barkingdog

P.S. I have to do just this as part of the datawarehouse test I'm running. Seems like a common task but I don't recall anything in SSIS addressing the issue.

SQL 2012 :: Create View From Multiple Tables That Have 1 To M Relationship

Jul 31, 2014

I have two table studenTtable and courseTable which is each student take more than one course . 1:M...for example Student1 take 2 courses (C1 , C2). Student2 take 3 courses (C1,C2, C3).I need to create a table/View that contain student information from StudentTable plus all the courses and the score for each course from CoursTable in one row.

for example Row1= Student1_Id ,C1_code ,C1_name ,C1_Score ,C2_code,C2_name ,C2_Score Row2= Student2_Id,C1_code, C1_name,C1_Score,C2_code ,C2_name ,C2_Score , C3_code,C3_name,C3_Score

and since Student one just have two courses , I should enter NULL in 'Course 3 fields'.My Struggle is in the insert statement I tried the following but it show an error

Insert Into Newtable ( St_ID, C1_code,c1_name, C1_Score ,C2_code ,C2_name,C2_score,C3_code ,C3_name,C3_score)
Select (Select St_ID from StudentTable) , (Select C_code,c_name,c_Score from Coursetable,SudentTable where course.Stid =Studet.stid) , (Select C_code,c_name,c_Score from course ,student where course.Stid =Studet.stid ), (Select C_code,c_name,c_Score from course ,student where course.Stid =Studet.stid );

I'm fully aware that the New table/View will break the rules of normalization ,but I need it for specifc purpose.I tried also the PIVOT BY functionality but no luck with it .I also tried writing a code using Matlab (because it is high level sw that it is easy to learn for people not expret in programming as me) but didn't know how to combine the Student and Courses Matrices in my loop.

Inserting Data Into Two Tables With Parent-child Relationship

Nov 13, 2006

I am trying to insert data into two tables with a SSIS package. One table has a foreign key relationship to the other table's primary key. When I try to run the package, the package will just seems to hang up in bids. I have found two ways around the issue but I don't like either approach. Is there a way to set which table gets insert first?

If I uncheck the check constraints option on the child table, the package will run very quickly but this option alters the child table and basically disables the constraint. I don't like this option because it is altering the database.

The second approach is to set the commit level on both tables to say 10,000 and make sure that the multicast component has the first output path moved to the parent table. I don't like this option because I am not sure if the records are backed out if the package should abend after records have been committed.

Copying Tables From 2005 To Another Is Failing

May 9, 2007

HI,
I current have two 2005 boxes running 9.0.3050 in different DMZ with the source running a DTS to drop and copy its tables to the source every night. It was working up until last thursday. Nothing has changed in the FW rules and getting no errors. One is 3.5GB which copies fine, the other is 21GB and runs all night with only getting a fraction of the tables populated. I'm the hardware guy, but have some understanding w/ sql. Thanks in advance for any help.

Transfer Of Data Between Two SQL Tables - Not Failing On PK Violations

Jan 5, 2001

Hello,

I am transferring data from one SQL table to another. The first table has a PK on the unique id only, the second table has PK on five fields (the idea being to reject duplicate records etc. etc.). I am using a DTS package to do this, but when run it will fail when it hits a PK violation. How do I getround this??????? What simple thing am i missing??

TIA DVNC

Dependencies Not Correct With Temporary Tables --&&> Replication Is Failing

Jul 13, 2006

Hello all,

here is a stored procedure I have:

CREATE PROCEDURE spU_GUI_AppliqueConditionFinancementPourGuichet
(
@GuichetId int,
@Validateur nvarchar(40)
)
AS
CREATE TABLE #tReservations (ReservationId int)

IF (dbo.GetSiGuichetEnRegle(@GuichetId) = 0)
INSERT #tReservations
EXECUTE spU_GUI_AppliquePerteFinancement @GuichetID, @Validateur
ELSE
INSERT #tReservations
EXECUTE spU_GUI_AppliquePerteAgrement @GuichetID, @Validateur


SELECT GR.Id,
dbo.FormateNoms(GR.Name) AS Names
FROM #tReservations
LEFT JOIN AnotherTable GR ON GR.Id = AnotherTable.id

DROP TABLE #tReservations
GO


The creation is ok but when I look to the dependencies, I see that it depends on GetSiGuichetEnRegle only.

For me, it shall also depend on

AnotherTable
spU_GUI_AppliquePerteFinancement
spU_GUI_AppliquePerteAgrement
FormateNoms

Apparently the dependencies are not calculated correctly because I'm using a temporary table.

My problem is that I have updated this stored procedures (and the two other that I call) to add a new parameter. As a consequence, when I do a replication, this is failing saying that I have an extra parameter. I imagine that because my dependencies are not correct, the replication is not occuring in the correct order and so it's still using the old definition of the stored procedure.

Do you have any idea on how I can force the dependencies to be calculated correctly ?

Thanks

Power Pivot :: Use Relationship Not Overriding Conflicting Active Relationship?

Oct 14, 2015

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.

How Do I Make SQL Database Tables?

Nov 28, 2005

No, I don't need a step-by-step (necessarily). I've been looking at W3Schools tutorial and it says to:


Code:


CREATE TABLE Person
(
LastName varchar,
FirstName varchar,
Address varchar,
Age int
)



But what is that? A text file saved with a .sql extension. Something typed at a command prompt? Is there an SQL interface?

Make A Join In Between 2 Tables?

Jan 17, 2012

I am trying to make a join in between 2 tables. One table which we can called func has 2 columns a and column b.

The other table which is called export has 16 columns. I will like to make a join in these tables and insert the result of the join into another table i have.

The table that is going to have the information has 4 columns, so I will get 1 column information from table export, and the other 2 column from table func, the other column shall be left in blank for the time being.

The problem is also that when i make a select from table export, there are only some values i want to get, this are values from a period where there is only the periods 11.

Select Company, A and B

FROM FUNC, EXPORT where period = '1101', '1102', '1103'

insert into new table?
