Given table A and table B where table A has a fk to table B’s primary key.
I insert a row into table B and want to know its id so when I insert a row into table A I’ll have the value for the relationship of the two rows.
How do I get the id of the new row I just inserted into table B?
Thanks.

Could You please tell me what am I missing here ?
Thanks a lot.
I have a MS-SQL 2005 database that is in a one-to-many relationship that is like this:
Table: Company
CompanyID, company name, address, city, etc.
Table Service States:
CompanyID, StateID
Table: States
CompanyID, StateID, State
The result is that you can have multiple states that are serviced assigned to any particular company.
Then in my ASP, I have a form for adding new companies to the database. On this form I have text boxes for Company name, Address, etc. Then for adding the states that are serviced, since you can have multiple states that serviced I decided to put in a Grid. This works fine if I'm editing the Company since the CompanyID already exists, but when I'm adding a new company, I can't INSERT INTO the Table Service States, since I don't know what the CompanyID is yet.
What would be the best way to handle this situation? I could probably put in a a ListBox with a Dropdown, then a little button with an add, add the items to the Listbox, then do an Insert on the Table Company, grab the companyID, then insert the items from the combobox.
I'm wonder if anyone has any better suggestions or ideas to handle this.
Thanks,
marly
I have two tables that have a one-to-one relationship. The reason they are two table is that one table has user data, whereas the other table has security information. The security information will be in a different security zone.
How do I do an insert into the two tables so that I do not get an integrity error?
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.
Hi
I need to read a file and write parent/child relationship rows. I cannot seem to fugure out how I can generate keys that I an use for the relationship.
I looked at using a variable, but have no joy - I cannot instantiate the variable and it errors - notsure wy.
I also looked to see if I can write to a DB table that maintains key id, but not sure how to do that.
I alo thought of setting up the parent table key to be auto-increment,but canot see how I can read this so that I can us it in the child row inserts.
Help will be really appriciated
Thanks in advance.
Hello,
This seems like such a simple problem but I am new developer even through I have been on the administration end of things for some time. I will go into more detail about my tables and there relationships below. Anyway, I am trying to create a many-to-many relationship within ms sql server 2005. I have created both of my primary tables and also a junction table per the directions on microsoft's website all per ms's instructions as stated here...
http://msdn2.microsoft.com/en-us/library/ms178043.aspx
At then end of these instruction it states as a NOTE: The creation of a junction table in a database diagram does not insert data from the related tables into the junction table. For information about inserting data into a table, see How to: Create Insert Results Queries (Visual Database Tools).
http://msdn2.microsoft.com/en-us/library/ms189098.aspx
and these directions do not go into detail on how to do an insert on a junction table. And I cant find out how to do this anywhere on the internet... I did create a T-SQL INSERT statement in a trigger as listed below but I end up getting an error AS LISTED BELOW....
Here is how I set everything up...
PetitionSet table consists of:
PetitionSetID int auto-increment primary key
PetitionSetName varchar(50) no nulls
PetitionSetScope varchar(50) no nulls
the Petition table consists of:
PetitionID int auto-increment primary key
PetitionSetID int no nulls
PetitionName varchar(50) no nulls
the SetToPetitionJunction table consists of:
PetitionSetID int
PetitionID int
And, there is a composite key made up of both the PetitionSetID and PetitionID fields.
I have created the foreign key relationships with DEFAULT VALUES from the SetToPetitionJunction table to each column's respective corresponding column in each of the tables: PetitionSet and Petition.
The trigger is on the Petition table and it has the following code:
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go
-- =============================================
-- Author: Name
-- Create date:
-- Description:
-- =============================================
ALTER TRIGGER .[SetToPetitionJunctionTrigger]
ON .[dbo].[Petition]
AFTER INSERT
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
INSERT INTO SetToPetitionJunction
(PetitionID, PetitionSetID)
SELECT Petition.PetitionID, PetitionSet.PetitionSetID
FROM Petition INNER JOIN
PetitionSet ON Petition.PetitionSetID = PetitionSet.PetitionSetID
END
I have created an asp.net 2.0 front end to insert values into the PetitionSet table and the Petition Table. And in the detailsview for the Petition table I manually insert the PetitionSetID field to the number that corresponds to an auto-generated number on the primary key of the PetitionSet table. So I am maintaining referential integrity...
The first time it works and inserts one record in the Junction table containing the PetitionSetID from the PetitionSet table and the PetitionID from the petition table.
Then when I try to add in another petition for the same petition set number just like I did the first time and then I get this error...
Violation of PRIMARY KEY constraint 'PK_SetToPetitionJunction'. Cannot insert duplicate key in object 'dbo.SetToPetitionJunction'.
The statement has been terminated.

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.

The 3 csv files were successfully imported into the ChemDatabase of my SSMSE.
2 questions to ask:
(1) How can I designate the Primary and Foreign Keys to these 3 dbo Tables?
Should I do this "designate" thing after the 3 dbo Tables are done or during the "Importing" period?
(2) How can I set up the relationships among these 3 dbo Tables?
Please help and advise.

Hello
I have need to write a query that I can pass in a bunch of filter criteria, and return 1 result....it's just ALL of the criteria must be matched and a row returned:
example:
Transaction table: id, reference
attribute table: attributeid, attribute
transactionAttribute: attributeid, transactionid
Example dat
Attribute table contains: 1 Red, 2 Blue, 3 Green
Transaction table contains: 1 one, 2 two, 3 three
transactionAttribute contains: (1,1), (1,2), (1,3), (2,3), (3,1)
If I pass in Red, Blue, Green - I need to be returned "one" only
If I pass in Red - I need to be returned "three" only
If I pass in Red, Green - nothing should be returned as it doesn't EXACTLY match the filter criteria
If anyone's able to help that would be wonderful!

View 7 Replies View RelatedHi,Do you guys know what's wrong with a one-to-one relationship?The reason I want to make it like this is that at the very end of the chain,the set of keys is huge. I want to limit the number of columns to be thekey. i.e. the [company] table has 1 column as the key. The [employee]table will have 2 columns as the key.e,g,If I add a [sale] table to the [company]-[employee] relationship, the thirdtablewill have 3 columns as the key -- "company id", "employee id", and "saleid".(e.g.)I have a company with many employees and computers. But instead of classifyall these, I just want to call all these as an entity. A company is anentity. An employee is just another entity. etc.So, instead of a one-to-many:[company]---*[employee]---*[sale]||*[computer]I make it one-to-one.[entity]---*[entity]If I want to know the name and address of the entity "employee", I will havea 1-to-1 table [employee] to look up the information for this employeeentity.[entity]---*[entity]||[company]||[employee]||[computer]||[sale]--[color=blue]> There is no answer.> There has not been an answer.> There will not be an answer.> That IS the answer!> And I am screwed.> Deadline was due yesterday.>> There is no point to life.> THAT IS THE POINT.> And we are screwed.> We will run out of oil soon.[/color]

I get this error when i try to create a relationship in a db diagram (sql 2005)
"'tblActivedir' table saved successfully
'tblClient' table
- Unable to create relationship 'FK_tblClient_tblActivedir1'.
Introducing FOREIGN KEY constraint 'FK_tblClient_tblActivedir1' on table 'tblClient' may cause cycles or multiple cascade paths. Specify ON DELETE NO ACTION or ON UPDATE NO ACTION, or modify other FOREIGN KEY constraints.
Could not create constraint. See previous errors."
What i have is 2 tables.
1 named client
1 named activedir
In the client table the columns i want to bind with activedirtable are FR1 and DC1
I want to bind them in the ID of the activedir table (both, in different fk relationships) so that they get the id of activedir.
Fr1 has an fk relationship with activedir (pk is activedir' id)
and DC1 exactly the same in another fk.
So i want both columns to comunicate with activedir.
If p.e. activedir has 3 elements (a,b,c) when i delete element a then werever FR1 or DC1 have this element(binded to it's id) then the element will also be deleted (id of the element) from both FR1 and DC1
I don't want to set Delete and Update action to none because i want the element changed or deleted from activedir, to do the same on Fr1 or DC1 or both.
Any help?
Thanks.
I am trying to create a 1:1 relationship, but not primary key to primary key. In table 1 I have a uniqueidentifier as a primary key. In table 2 I have an int as the primary key and a column that takes the uniqueidentifier from table 1. Everytime I drag and drop the relationship line and link table 1 to table 2 it creates a 1:N relationship: ie. tbl1.primarykey links to tbl2.column2. So I'm not linking primary key to primary key however I still want a 1:1 relationship.
How do I do that?

This should be simple. What am I doing incorrectly?

Hi there everyone, this is my first post so go easy on me :)
Basically I am trying to get my database to copy the value in the UserId (unique identifier field) from the aspnet_Users table to a foreign key UserId in a table called userclassset. I have made this field the same datatype and created a relationship between the two. Unfortunately, when I add a user using the ASP.Net configuration tool it does not automatically copy this value into my own custom table. I have noticed it is however automatically copied into the aspnet_Membership table. Any pointers on how to solve this would be great!
Thanks :)
Hi, how can i make optional relationship?
for example: In table A, there is column 1, column 2, column3. In table B, there is column 4, column 5 and column 6.
column 1 and column 2 are primary keys for table A and table B. The relationships between table A and table B are column 2 and column 5; column3 and column 6. but optional (ie. when data exists in column 2, then column3 is null)
how can i set the relationship? because one of the columns data is null each time, error always occurs.
