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?

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?

I need to produce a from where I can add multiple parts. Each time a user enters a part number, the description should be populated. The user can then click add and this part and description will be shown below. They have the option to add as many parts as they require. Once all parts are added the user fills in some general info eg description and then once a submit button is clicked all part info will be inserted into a table and general info will be inserted into another table with one unique ID.

Maybe this could be a simple questino, but for me it's difficult to do this action: I have a table in sql server 2005 with some records stored, for example 10 records. The primary key of this table, let's call it "Employee", it's a number field with an autoincrement constraint. I want to store more data into the table by using a OdbcDataTable object and OdbcDataAdapter and adding new rows to the datatable and afeter that use the "Update" method from the OdbcDataAdapter object.
The big deal is this: let's suppose that I want a add a new record to the datatable object, using any method or code sequence that you want. if I have 10 records stored on the data base table, when I retrieve this table schema by using the OdbcDataAdapter "Fill" method, I have a copy of the data base table schema in the DataTable object, right?. if I add a new row on the datatable object, it's suppose that the primary key column of that table must AUTO-INCREMENT the value of the key, I mean if the last value that I store on the table was the number 10 on the PK field, when I add a new row on the datatable object, the PK value on the datatable object must be the number 11 if the autoincrement constraint is present into the DataTable object, but in my case, it doesn't work
So, How can I define the conditions or set the c# data objects properties to wor in that way???. In this moment the PK column on the odbcDataTable doesn't auto-increment its value when I add a new row on it.
Please helpe with this.
PD: I have another question about the DataTable object, how many records can store this object?? I have some problems with this because sometimes when I use the Fill() method to get data into the DataTable or a DataSet object there's no problem if the Fill() method retrieves about 142000 records, but when I retrieve over the 145000 records, when I inspect the DataSet or DataTable object by using the debuging mode, they have null value. Any of you can tell me why this situation ocurrs??

Table 2
Order_Id int PrmKey FK1
Item_Id int PrimKey FK2

I'm having difficulty adding a repeating header row, every x rows, to a gridview. I'm able to add the header only once with the below code. For some reason it will only add it during the last iteration through the for/next statement. I tried manually adding three separate .addat statements to different rows and it only executed the last .addat statement. I couldn't find any information on why it's only working the one time and I hope someone has a fix or better solution.
Code snippet (Note the IsWhole() function verifies that the rownumber divided into a whole number):
Protected Sub Gridview1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles Gridview.DataBound
Dim grid As GridView = TryCast(sender, GridView)
If grid IsNot Nothing Then
Dim row As New GridViewRow(0, -1, DataControlRowType.Header, DataControlRowState.Normal)
Dim header As GridViewRow = POSTURE_RESULT.HeaderRow
For i As Integer = 0 To POSTURE_RESULT.Columns.Count - 1
Dim TableCell As New TableHeaderCell()
TableCell.Text = header.Cells(i).Text
row.Cells.Add(TableCell)
Next
Dim t As Table = TryCast(grid.Controls(0), Table)
If t IsNot Nothing Then
For i As Integer = 0 To Gridview1.Rows.Count - 1
If IsWhole(i / 5) Then
t.Rows.AddAt(i, row)
End If
Next
End If
End If
End Sub

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.

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?

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'

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.

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.

I have 3 tables
Restaurants
IDNameAddress
Location
ID (Foreign Key)LocationID
Food
ID (Foreign Key)FoodID
Here's what I want to do, I have two variables @FID(food ID) and @LID(LocationID). I want something like
select * from restaurant where ID in (( select ID from location where locationID = @LID) AND (select ID from Food where FoodID = @FID))
The bold part is where I'm having problems. I want it to check both the Location and Food table for a match.
I'm having a hard time putting it into words :p I hope you get what I mean

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]....
