SQL Server :: Foreign Key On Multiple Tables?

Jan 30, 2011

I have four tables namely tblStudent, tblParent, tblEmployee and tblUnwantedVisitor.

tblUnwantedVisitor should get the primary key from the three tables, which is the visitor ID, tblStudent visitor ID starts from 10000, tblEmployee from 20000 and tblEmployee from 30000.

I used foreign key from one to one table only, so I don't know if my approach for the database is wrong or foreign key for multiple tables, which is somehow unlikely, is necessary.

Feb 27, 2011

I have two tables with a foreign key constraint how can I delete rows from both of them in one transaction? linq to SQL seems to call my deletes in the wrong order. Is there somewhere I can check and make sure the constraint is recognized properly by linq to SQL??

DataContext.OtherImages.DeleteOnSubmit(myOtherImage);
DataContext.Images.DeleteOnSubmit(myImage);
DataContext.SubmitChanges();

The Foreign key constraint is on OtherImages.

SQL Server :: How Do You Add Rows To Multiple Key Tables

Jul 24, 2010

I am accessing rows in an SQL database table based upon the contents of the Primary key and another column. But, I cannot insert new rows in the table when the content of the new Primary key column already exists in another row. Can I define the table with a multiple column Primary key so that a unique value can be based upon the content of both columns?

SQL Server/T-SQL - Update Multiple Tables At A Time ?

May 21, 2010

I have two tables, Customer and CustomerPhone.

Single record in Customer can have multiple CustomerPhone records. As you see in the image below, Phone and Fax resides in CustomerPhone table whereas the rest of the fields resides in Customer table. If user want to edits a customer record, obviously i will have to update the record in Customer table and at least two records from CustomerPhone (Phone and Fax).

I could write two update statements, one Update customerPhone and the second update Customer table. Is there a better solution?

SQL Server :: Select Statement For Multiple Tables

Oct 1, 2010

SELECT u.Email FROM UserProfiles p, aspnet_Membership u WHERE p.RulesCheckBox = 'True' AND u.UserId = p.UserId This gives me a list of registered member email addresses that have selected the RulesCheckBox in their profile, so I can email them with an email script. There is a relationship between the Membership table and the UserProfile table, so it finds the email addresses from the Membership table where that user has the RulesCheckBox checked in their profile (in UserProfiles table). I'm wanting to add some additional names to this list, from a different table. The purpose is so I can manually add email addresses to the additional table, so the additional email addresses will also receive the same email, even though they aren't registered members of the site. So how can I adjust that SELECT statement so this one is combined with it somehow?:

SELECT Email FROM ExtraEmails WHERE Rules = 'true'

Searching In Multiple Tables Using MS SQL Server 2000?

Sep 14, 2010

We have a database with a lot of information about Persons. I won't post the entire database structure because it is too big, but it looks something like this:

Person
ID
Name
Street
City
State
Country
Language
LangCode
Language
Interest
ID
LastChangedBy
LastChangedOn
LocalizedInterest
InterestID
LangCode
Description
PersonInterest
PersonID
InterestID

Now, this is just a small example. In our database, we have about 8-9 localized tables (like Interest) a Person can be linked to. A Person can have multiple Interests, a Person can have multiple Jobs, a Person can have multiple Educations, a Person can have multiple Experiences, I have to build a search function. Let's say you enter "tom" as the search term. This should give a list of all Persons with "tom" in their Name, Street, City, State, Country, in one of their Interests, in one of their Jobs, in one of their Educations, in one of their Experiences or in one of the other linked tables.

If you enter multiple words to search for (eg. "tom php"), it should give a list of all Persons with "tom" in their Name, Street, City, State, Country, in one of their Interests, in one of their Jobs, in one of their Educations, in one of their Experiences or in one of the other linked tables AND "php" in their Name, Street, City, State, Country, in one of their Interests, in one of their Jobs, in one of their Educations, in one of their Experiences or in one of the other linked tables. At the moment there are about 4,500 records in the Person table and if I do an outer join of Person with all the tables I have to search, there are about 1,300,000 records and 40-50 fields to search in.

How should I approach this problem so that performance will be acceptable? The client expects "something like Google" in terms of speed and ease of use. We're using MS SQL Server 2000 and ASP.NET 2.0. The search functionality has to be added to an existing application and changing the technology or database structure is not an option.

SQL Server :: Updating Multiple Tables Simultaneously

Sep 8, 2010

Was wondering if someone can help me out with this multi update problem

I have a webform that populates a single table but due to certain dropdown data conditions it could also potentially populate 3 other tables

The tables information populates a gridview with amounts from accounts etc..

e.g.

Table 1

Site DataType account update

34 SS 12.50 N

Table 2

Site account

34 12.50

Say the above entry has the updated column changed to Y via the webform the amount 12.50 should disappear from the gridview. I was

a bit shortsighted and added the additional tables afterward. The information on the gridview pulls from the additional tables and since

the first table and the additional tables are not linked the data still stays the same in the gridview

I do have an Id column on both tables but unfortunately I added the rest of the tables after the first one so the Id's do not really match.

MVC :: How To Create A Controller And View With Data Coming From Seprate Tables Associated With Foreign Key

Mar 8, 2011

I am using Entity Frameowrk as the ORM. I am new to MVC and trying to develop a samll module as a learning project.

Now I am stuck with an issue for which I can't seem to find out answer on web. The issue is :

I have two tables mapped as entities - Tenant_Definition and Contact

Tenant_Definition { Tenant_ID , Desc, Contact_ID}

Contact {Contact_ID, Company_Name,Company_Address,Person_Name, Person_Phone_Mobile}

My View has to present a form that shows Tenant Desc and Contact related fields. The index view works fine and shows the desired values.

But, the create view isn't working out. In the create view, i am planning to do -

1. creating a new contact entity instance and saving it in db

2. Then creating a new tenant entity instance using the new contact_id and save it to the DB.

However, the code doesn't seem to be inserting any value inside Contacts table. It inserts null value.Below is the code snippet of my Create Controller -

[HttpPost]
public ActionResult Create(FormCollection collection)
{
var newContact = new Contact();[code]....

SQL Server :: Customer Referenced In Multiple Tables Vs Big Join?

Dec 23, 2010

Just looking through database design and wondering what would be the better option. I have customers, who all have orders, pickings, deliveries and invoices. Now an invoice can't exist without a delivery, a delivery can't exist without a picking and a picking can't exist without an order. So I could set the tables up in a linear fashion. e.g.

Customer -> Orders -> Picking -> Delivery -> Invoice

then in Orders, there would be an ID field, with a customerID field and in Picking, there would be an ID field, with an orderID field and in Delivery, there would be an ID field, with pickingID and in Invoice, there would be an deliveryID field. Linking them altogether, again, in a 'linear' fashion.

The problem is if I want to get, say, all the invoices for a specific customer, my query would be something like

[Code]....

My other option would be to have in a customerID column in each of the tables meaning a much easier query

[Code]....

Originally "LoadDate" column (see below scripts) was there both in tables DIM_Table_1 and DIM_Table_2

According to change in requirement, LoadDate in both the tables to be chnged to LOAD_DATE. It has to be done through script

EXEC sp_rename 'dbo.DIM_Table_2.LoadDate',
'LOAD_DATE', 'COLUMN' -- Error: See below

SQL Server :: Adding Rows To Multiple Primary Keyed Tables?

Jul 27, 2010

I am accessing rows in an SQL database table based upon the contents of 2 Primary key columns. But, I cannot insert new rows in the table when the content in one of the new Primary key columns already exists in another row. I get an error message that says: "Violation of PRIMARY KEY constraint 'PK_ReferendumVoters'. Cannot insert duplicate key in object 'dbo.ReferendumVoters'. The statement has been terminated."

The reason why this error is occurring is because I first stored "Referendum 1" in one column along with "me" in the second column of a new row for a "ReferendumVoters" table. Then, I attempted to insert a new row with the same "Referendum 1" string in the first column along with a different name in the second column. But, it will not let me do this even though I created a new index that defines the two columns as unique. Is there any way that will enable me to do this?

SQL Server :: Slow Running Query Based On Multiple Tables Using Joins

Nov 15, 2010

One of my peer wrote a query based on multiple tables using joins. One of the table is in a different database The query was taking much time

1. Create an SP
2. Create a temp table and copy all records from the external db
3. Avoid using Left Join as much as possible and use Inner Join
4. Create and use indexes
5. Remove tables/columns that are not necessary

In this scenario, I would like to suggest to use Covering Index, but how can it be created for multiple tables and a temp table?

SQL Server :: Selecting Data From Multiple Tables Whilst Using A Union Statement?

Nov 29, 2010

I basically have a series of tables from one database that have an identical structure thus making retrieval of all records fairly easy (I just use a UNION ALL statement). However I need a list of values from another table within a different database that contains information regarding the group of the data.

I so far have the following:

SELECT Table1.* FROM Table1 UNION ALL SELECT Table2.* FROM Table2 UNION ALL SELECT Table3.* FROM Table3 UNION SELECT Database.dbo.SRFILE.SR_GROUP FROM Database.dbo.SRFILE INNER JOIN Database.dbo.SRFILE.SRONUMBER = Table1.Incidentx

I keep receiving a unable to parse message however all I need to retreive is the SR_GROUP value but just don't know the correct syntax. Is it actually possible to do this as the structure of SRFILE is not the same as Table1/2/3.
