hello,
I am beginner for asp.net and sql server. I used Sql server manegement studio full version and I exported my aspnetdb which was created by VS2005 to my host sql server. I have a question:
relational tables are not relational no longer. I noticed that when I created database diagram. what is wrong by exporting?
thanks for your helps...
Hi all,
I am trying to create a diagram for our database, during the creating, I create some of the relationships which were not there(basically our original database is not relational database, that's why I am doing it)
So sometimes I have to chage data type in order to create a relationship for the coloumns in different tables. i.e. change char(16) to varchar(7) (I checked the field that make sure all the data in this field is <= 7 characters)
But when I saved the diagram, there is an error message that state:
Errors were encountered during the save process. Some of your database objects are not saved on your diagram.
'agent' table saved successfully
'VisitUSA' table
- Unable to create relationship 'FK_VisitUSA_agent'.
ODBC error: [Microsoft][ODBC SQL Server Driver][SQL Server]ALTER TABLE statement conflicted with COLUMN FOREIGN KEY constraint 'FK_VisitUSA_agent'. The conflict occurred in database 'CMC', table 'agent', column 'AgentCode'.
What does that mean? is it caused by some of the agentcode data in VisitUSA table which is not in agent table?
Thanks!

Hi, not sure if this is the right forum for this question.
I am creating relational tables for the first time in sql server express. I will have an orderItems table and an orders table. the MenuItems table is the problem. It is a catalogue of books. There will be about ten columns. all are unique to each book. i.e isbn number, title, author, publisher etc. but ten columns seems to be quite cumbersome. it may be easier to break the table down into two tables (i.e. primary details and secondary details perhaps) However to populate the table in the first place it would be easier to have it as one table instead of opening and closing 2 tables Adding the odd book to the two tables in the future would not be a problem. so the question is can i create a table and then brak it into two relational tables afterwards. If so how do i do this. this is my foirst go at relational tables and i am still trying to get a handle on visualising them. If my logic is up the wall please let me know....

I understand the basics for doing an insert. Their seems to be many ways of achieving the same thing in .net. I have used the tableadpaters and sqlcommand functionality to achieve this. My one question is how foregin keys should be created in associated tables. EG so if i create a new record entry in one table and the primary key for that entry is a foreign key in another table, do I need to call 2 table adapters, or run 2 sqlcommands(taking the primary key from the first traction and use this in the next transaction)?
Any help or direction for some good tutorials on this would be much appreciated.
Thanks

Hello friends .....What is the answer for this question in frame of SQL 2005 Management Studio or SQL Server 2000 ?
What are the properties of the Relational tables?
Ok, I have a page on my website where we can add products to our database. We are a music store, and most products have different versions or colors. I've created 2 tables, Products and Subproducts. The products table may hold info like Fender Stratocaster, and the subproducts would hold colors (Blue, Sunburst, etc). The subproducts table has an integer field called MainProductID, which is linked to the mainproducts table field RecordID. So far the page uses a wizard where if first creates the main product using an sql datasource. After the data has been added to the main products table, my page gives you the opportunity to add different sub products. The problem I am having is actually feeding in the RecordID from the main products table to my insert parameter on the sub products data source. This is what I have tried so far: There is a formview on the page that is bound to the main products table, after the entry is created I can physically see the info on my screen, so I know the data is there at my disposal SubProductsDataSource.InsertParameters.Add("@MainProductID", Formview1.datakey.item("RecordID"))SubProductsDataSource.Insert()Using this adds the data to the table, but the MainProductID is nullalso is there a cheap little way to refresh a page, because when I upload the product images I have it go to the next step where you are supposed to be able to see the images you uploaded, I don't see them which makes me think that the page is loading faster than the images are uploading. Thanks

I am trying to insert data into 2 different tables. I am using dataadapter and dataset.
Protected Sub SubmitButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles SubmitButton.Click
Call ConnectionString()
Dim insertSQL As New SqlCommand()
insertSQL.Connection = sqlConn
insertSQL.CommandText = "SELECT location.CountryName, location.CityName, location.BuildingName, location.FloorID, rooms.name, rooms.FloorID AS Expr1 FROM location INNER JOIN floors ON location.FloorID = floors.id INNER JOIN rooms ON floors.id = rooms.FloorID"
Dim ds As New DataSet()
Dim da As New SqlDataAdapter()
da.SelectCommand = insertSQL
Dim scb As New SqlCommandBuilder(da)
Try
da.Fill(ds)
Dim ndr = ds.Tables("location").NewRow
Dim ndr2 = ds.Tables("rooms").NewRow
ndr("FloorID") = FloorIDDDL.SelectedValue
ndr("CountryName") = CountryNameTextBox.Text
ndr("CityName") = CityNameTextBox.Text
ndr("BuildingName") = BuildingNameTextBox.Text
ndr2("name") = RoomNameTextBox.Text
ndr2("FloorID") = FloorIDDDL.SelectedValue
ds.Tables("location").Rows.Add(ndr)
ds.Tables("room").Rows.Add(ndr2)
da.Update(ds)
ErrMsgLbl.Text = "Information saved successfully"
Catch ex As Exception
ErrMsgLbl.Text = ex.ToString
End Try
sqlConn.Close()
End Sub
The above code does not throw any error. It also does not update the tables.
Your help will be appreciated.
Thanks!
I have two tables with data that I need to get and display in a combobox. What I want to do is have the parent table listed in the combobox with all of its children indented. Sorted by parent then by child.
This SQL seems to be more complex than I have done previously
I can get all of the records from both tables easily:
Code:
SELECT strName, ID FROM tblParents as pp
INNER JOIN tblChildren as cc
ON cc.pID = pp.uiGUID
UNION (SELECT strName FROM tblChildren as c
INNER JOIN tblParents as p
ON c.pID = p.ID)
However, this simply returns a list that is not ordered in any fashion. I'd like to have all of the parent's children shown under the parent name (there is only 1 parent per child and multiple children per parent)
I've got a lot of XML like this (simplified):
Code Snippet
... 8 MORE
... 9 MORE TIMES
I need to get this into three existing SQL Server 2005 tables, each with identity columns for their primary keys:
Code Snippet
CREATE TABLE ELEMENT1 (
[ID] INT IDENTITY
)
CREATE TABLE ELEMENT2 (
[ID] INT IDENTITY,
[ELEMENT1_ID] INT
)
CREATE TABLE ELEMENT3 (
[ID] INT IDENTITY,
[ELEMENT2_ID] INT
)
With primary and foreign keys as you'd expect, and, of course, many more columns!
How would I get this into tables through SSIS, preferably in a high-performance manner (there may be several gigabytes of XML to load).
The issue, of course, is that in order to insert an ELEMENT2 row, I need the ID from the coresponding ELEMENT1, etc.
Any ideas or pointers to articles would be welcome.
I'm shredding the below xml into relational tables. Each element of the xml has it's own table and there is a foreign key to join the tables, you can see this in the below picture. The process I follow is each relational table I always bring the nesecary xml and store it in the table and when shredding I always look at the parent table.So for example when processing the seat table, I use seat xml from the parent route table, also taking the ROUTEID from the route table. The reason I do this is all about taking the id from the previous step to create the relationships between the tables. without taking the xml down to the tables?The problem with this approach is I have xml stored in most tables and the tables are becoming very large.
<Route Type="OneWay" >
<Seat Type="FirstClass">
<Prices>
<Price Price="10" />
<Price Price="11" />
</Prices>

View 6 Replies View RelatedHi all! I am working on a piece of SQL at the moment and I'm getting a little confused. I have 3 tables: Items, Attributes and a table linking them. I have 5 attributes and an item can have any of the 5 attributes. So my linking table holds the ItemID and the AttributeID and there can be 1-5 entries for each Item. A user can search for items based on Attributes; so they can tick 5 checkboxes that represent the 5 Attributes. So I need to build a query based on their choices. At the moment I'm using:Select * FROM ItemsINNER JOIN linking on Link_ItemID = Item_IDWHERE Link_AttributeID IN (10, 13, 17)But this brings out the Item that have either AttributeID of 10 or 13 or 17 whereas I need it to pull out ONLY items that have a AttributeID of 10 AND 13 AND 17.Can anyone help with this query? Sorry if this is badly worded. The solutions is prolly something really simple I have overlooked... :SI've also tried:Select * FROM ItemsINNER JOIN linking on Link_ItemID = Item_IDWHERE Link_AttributeID = 10 AND AttributeID = 13 etcBut obviously that won't work! :s

I'm using VB.NET,ADO.NET in ASP.NET .
Microsoft .Net framework 1.0
Windows 2000
Visual Studio IDE
and SQLServer.
I have to create to tables as
Table1 contains ID,Name
Table2 contains ID,Marks,Foreign Key ie Primary key of the table Table1.
Give me an information how to create these two tables in SQLServer (I know how to create a table but i don't know how to create a table which includes Foreign Key.)
Then using Dataset i want to display the records as Name,Marks which are stored in two tables.
I have studied that in ADO Join query and record set object is used but it gives a problems and it is not good when we want to transfer the data between two applications or pages but dataset solves all those problems.
Give me an information about it.
Kindly help me
Thanks in advance

what is the difference in making relational databases in SQL vs. Access? Do you need to make them if you will be using ColdFusion? What do the other fields in minor tables need to be in order to connect them to a major table when it will all be based on a number that is in the major table? i'm kind of confused on this issue...Thanks!
View 1 Replies View RelatedI have a database with 3 tables in a many to many relationship.
EmployeeGamingLicense
EmployeeDocuments
EmployeeRenewals
I created the third table to hold the employeerenewal dates, I did this because I cant have repeating vaules in the primary table. I am just making sure that my course of action is the correct one. The purpose of the Employeerenewals is to give the users an indication that a certain renewal has been processed, because in the past there was several hundred that were not processed. The problem was that the users had no way of knowing this. What I was thinking was having the primary table calculate a renewal date based off the finalsuit and show the results in the Employeerenewals with a yes of no drop down. Now the yes or no drop down box will be give the users their red flag if the renewals have been processed or not.
Does that make sense??
Thanks guys :)
Hi
I am developing a website current and i have a database that seems to be growing very rapidly..
I would like to ask if anyone knows of any good tutorials/examples on relational databases?
Also does anyone know of any good database design tutorials/examples?
If it helps i am using Microsoft Visual Web Developer
Thanks
If you think you know it all?! You know nothing!
If I have a table that contains default values or a constant values do I have to relate it to my other tables that might need them. Thanks in advance.

My question:
How to have an unknown number of authors returned for a list of books, with the multiple authors being returned on the SAME row as each book
My table structure:
Table A - Books
-------------------
BookID | BookName
-------------------
1 | Book One
Table B -
RelatingTable
-------------------
BookID | AuthorID
-------------------
1 | 60
1 | 61
Table C - Authors
-------------------
AuthorID | AuthorName
-------------------
60 | Bob
61 | Joe
My query:
SELECT * FROM Books, RelatingTable, Authors AS a
INNER JOIN Books AS b ON b.BookID = r.BookID
INNER JOIN RelatedTable AS r ON r.AuthorID = a.AuthorID
Output I am getting:
-------------------------------------------------------------------------
b.BookID | b.BookName | r.BookID | r.AuthorID | a.AuthorID | a.AuthorName
---------|------------|----------|------------|------------|-------------
1 | Book One | 1 | 60 | 60 | Bob
1 | Book One | 1 | 61 | 61 | Joe
-------------------------------------------------------------------------
Desired output:
-----------------------------------------------------------------------------------------------------------------------------------------------------
b.BookID | b.BookName | r.BookID[0] | r.AuthorID[0] | a.AuthorID[0] | a.AuthorName[0] | r.BookID[1] | r.AuthorID[1] | a.AuthorID[1] | a.AuthorName[1]
---------|------------|-------------|---------------|---------------|-----------------|-------------|---------------|---------------|----------------
1 | Book One | 1 | 60 | 60 | Bob | 1 | 61 | 61 | Joe
-----------------------------------------------------------------------------------------------------------------------------------------------------
The desired output does not have to be like an array - I only assume thats what it would need to be
If you can post anything to help me get in the right direction I would really appreciate it
Thanks for your time!
Hi,I have a very simple question.In what cases are relational databases necessary?Are they really necessary in cases where only asingle type of query is to be performed based on one uniquefield or can we just put all fields together in a single databaseand just access them through that unique field?
View 6 Replies View RelatedHi,This question has been bothering me for some time. A lot of peopleseem to "think" XML is the king of data problems, and I've heard thatnext version of SQL Server is going to have a strong XML flavor,meantime, I seem to get the impression that a large number ofhard-core relational model gurus do not seem to be that impressed withXML (technical value of this extra layer seems to be limited whilebusiness value might be substantial for instance, more software work,more disk space requirement etc. etc.). What's your take on this?Generality or specifics, all welcome. One specific question is, howcan XML supplement relational model?Thanks.

What is a "Relational Database"?
Thanks,
Aldo.
I have a few questions for you guys. I have a client
application that can be offline or online. While offline, records can be added and need to be later synced to production.
I will use rda to pull the table down, and this is working fine. Now what if I
have multiple tables where I want a foreign key relationship?
With rda I can only pull down one table at a time from
everything I've read. Now say create a constraint after pulling the two or more tables down. While in offline mode I create a new record on two seperate tables with foreign key/primary key relationship.
When I do the push to the server will it automatically
update the foreign key reference (locally) to the right one on the production
server? Or will I get a duplicate primary key error? On the production server the primary key will be different because of the identity. This is very important because I will have multiple clients.
Thanks in advance
I am just now starting the switch from .NET 1.1 to .NET 2.0. I really like the new way of using the SQLDataSource and setting up Views declaratively as opposed to doing it all in code, which brings me to my question.In some of my applications I have a single Stored Procedure return multiple result sets to a single DataSet where I have a DataRelation set up. Then I can have nested DataGrids that use the GetChildRows() method to filter the results to display the hierarchical data. I would like to do something similar with the SQLDataSource and GridViews but haven't found a way to get multiple result sets.One thought I had was to create a Strongly Typed Dataset and then use the ObjectDataSource object, but I still didn't see a way to get child rows out of the datasource. I've seen an example that uses a <FilterParameter> to get nested data, but there is an extra trip made to the server for each parent item as it just put an extra parameter in the WHERE clause of the query.

This is a bit of a trivial question, since I know how to actually create the code in SQL. Hope this is the right section to post it in too, since it sort of concerns design I guess..
My problem is how to I represent the following SQL query in relational algebra:
SELECT *
FROM Staff;
Since I'm using SELECT, I assume I use selection to represent it, so would it be as "ó(Staff)" [using the sigma symbol, in case it doesn't show]? But as I'm not specifying a predicate since I wish to select all fields in Staff, would it be simply represented as "Staff"?
I appreciate any help... it's been baffling me for a while
Hotel(hotelno, hotelname ,city)
Room(roomNo, hotelNo,type,price)
i need the reltional algebra to list the price and type of rooms in the hilton hotel
thanx
