Need To Insert Data Into 2 Tables, Relational Having Problems

Mar 7, 2007

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 null
also 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

Insert On Relational Tables

Apr 7, 2008

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

Insert/Update Relational Tables Using Dataadapter

May 2, 2008

Hi!

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!

Designing Relational Tables

Sep 22, 2007

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....

Hello, I have a Stored Procedure which insterts into Orders table. Orders table is the parent table, with primary key OrdersID. I also have a child table, Client, with foreign key OrdersID. I want it to insert the data into the orders table, and at the same time insert the OrdersID into the FK of the child table. Any info would be appreciated. I have no idea how to do it.

Cannot INSERT Data To 3 Tables Linked With Relationship (INSERT Statement Conflicted With The FOREIGN KEY Constraint Error)

Union Two Tables With Relational Ordering / Grouping?

Jul 16, 2012

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)

Guidance Needed: Loading Hierarchical XML Into Relational Tables

Aug 8, 2007

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.

SQL XML :: Shred To Relational Tables - Creating Foreign Keys

Oct 7, 2015

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>

Create A Relational Diagram From Non-relational Database

Aug 4, 2005

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!
Betty

Relational Data And RDA

Aug 1, 2006

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

SQLDataSource Relational Data

Nov 14, 2005

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.

Data Insert In Tables

May 8, 2008

I have timecard records need to be inserted into the EMP_TC table automatically. This job should run every day to create EMP_TC records for the full current month for any ASSIGNMENT_ID€™s where ASGNMT_END_DATE is either null or greater than the run date of this job and PRD_START_DATE is in the current run month.
PRD_START_DATE is always Sunday, PRD_END_DATE is always Saturday. For example, if an employee starts a new project on 4/8/2008, the first timecard record in EMP_TIMECARD for that EMP_ASGNMT_ID should be 4/6/2008 €“ 4/12/2008. If PRD_END_DATE is null then the job would populate the following 4 records for the EMP_ASGNMT_ID:
i have currently stored procedure doing this but i had to specify the dates manually .how could i automate this process.
i can avoid stored procedures needed but i am really confused on what logic to apply to it.
We need to pick the assigment id and dates automatically from employment assignment table.
Assignment id is nothinb but a identity coloum please advise

Using A Sub Query To Return Relational Data

Jan 19, 2008

Hi i am trying to use this query to pull all the publications stored in the database and all the authors contributing to that publication (1 to many relationship). I am trying to use a sub query so that i can display the results on one row of a gridview (including a consecutive list of all the authors). However i am recieving this error: Incorrect keyword near the word SET. ?
 
Maybe i need to add a temp column in the sub query to pull all the related authors for a single publication - but i dont know the sql for this? can anyone help?
 
Thanks
 SELECT ISNULL(Publication.month, '')+ ' ' + ISNULL(convert(nvarchar, Publication.year), '') as SingleColumn,  Publication.publicationID, Publication.title FROM Publication WHERE Publication.publicationID IN (SELECT (convert(nvarchar, Authors.authorName)) FROM Authors INNER JOIN PublicationAuthors ON Authors.authorID = PublicationAuthors.authorID) AND Publication.typeID IN (SELECT PublicationType.typeName FROM PublicationType INNER JOIN PublicationType ON Publication.typeID = PublicationType.typeID

How To Flatten Relational Data For Analysis

Mar 22, 2007

Hello everyone, this is my first post here so hopefully I am not asking a common question.

I am trying to create a flat dataset in SQL 2005. Basically I run a query and I get multiple rows for the same primary key. The query I am running is quite large and has several different tables connected to it, here is a small sample of what it looks like...



Typeid(Primary Key) Individual Address

1 Sam 912 Ave. J

1 Sam 913 Ave. Q

1 Sam 914 Ave. R

2 Mike 1000 Ave. O

3 Jill 1001 Ave. O



I want it to kind of look like this

TypeID Individual Address_1 Address_2 Address_3

1 Sam 912 Ave. J 913 Ave. Q 914 Ave. R

2 Mike 1000 Ave. O

3 Jill 1001 Ave. O



As I said before, this query is pretty big, and has several variables like Address where multiple rows are being taken by one Primary Key.

If it is not possible to do this in SQL 2005, is there a program that may be able to? Right now we are using SPSS as sort of a bandaid... we run the query in small portions like the one in the sample and then restructure the in sections but this takes several hours.

Anyways, thanks for any help that you may be able to provide.

Fast Loading Relational Data

Apr 8, 2006

I am searching for a way to fast load relation data. I know how to load data fast but how can i store relation data fast.

For example :

Table1 ( tabel1Id int identity , name varchar(255) )

Table2 ( tabel2Id int identity , table2Id , name varchar(255))



When i insert 50 records into Table1 i can't get the 50 identity fields back, to insert the related data into Table2.



I think one of the solutions could be returning a selection of
Table1 joined with syslockinfo, but i have no idea how to do it.



Does anyone have an idea?

Xml File Import - Relational Data

May 19, 2006

Hi,

I have played around with SSIS in addition to reading an SSIS book front to back, but I am still a little confused as to how to import an Xml file with relational data.

The Xml file is structured as follows:

<products>
<product>
<name>
<id>
<category>
<name>
<id>
</category>
<fields>
<field>
<name>
<value>
</field>
<field>

<name>

<value>

</field>
</fields>
</product>
</products>

Basically I want to import the Xml data into three tables: categories, products and fields. A product can belong to one or more categories and has one or more fields which store information about the product.

Using the Xml Source component I can load the Xml from the file, but I can only output one section (category, product or field) at a time. Since the relationship is infered from the hierarchical structure of the Xml (e.g. the fields don't store an ID of the product they belong to), I am not sure how to import the relationships into my tables.

If anyone has any tips on how I can go about that, then it would be most appreciated :)

Thanks!

Insert Data In Multiple Tables

Apr 27, 2007

Hi there!!! Trying to figure something out, I have searched this forum but no answer to my dilemma.

I have three tables on a database that I have to insert new data and update the old one. The structure of the tables is like this:

Table1
custid int primary key,identity
fname varchar(30)
lname varchar(30)

Table2
fileid int primary key, identity
ssn varchar(11)
custid int foreign key

Table3
statusid int primary key,identity
title varchar(18)
fileid int foreign key


This is very general but that's the idea. Now I receive a text file with the necessary info, I've already parse and break down the file into the correct fields.

Now for my question, how I insert the relevant data onto the tables from this one parsed file? and also how I go about inserting the primary keys from the different tables onto the foreign keys of each tables?

I tried relationships and key indexes, but it just spew a bunch of errors, that I'm investigating.

Any ideas, pointers, tuts, something I'm missing?

BTW I'm using sql 2005 express and VB.net


Thanks in advance for any help.

Matching Relational Records. Is It Possible Using Data Minig?

Jun 20, 2006

Problem:
I am working on a price comparison system which matches the best prices for a purchase (or an order) from exisiting purchase data.
The order is stored in multiple tables including order details (stores major items purchased: e.g., PC) and order sub-details (optional items purchased with the major items: e.g., speakers, backup device, webcam etc.).
There could be a number of major items in an order and each major item could have multiple related sub items. The other variables that affect the price include trade-ins if any, sales going on at the time of order, number of units etc.

Now, for any new configuration (major items/related sub items), the system should be able to return a list of previous purchases made with similar configurations, and similar variables (quatities, trade-ins etc). Even if the same model is not present, similar pcs by the same vendor should be considered. etc etc.

Questions:
Is this possible using Data mining?
If yes, which algorithm is recommended?

Also, can I assign/modify any kind of weights to certain variables (if same model: .6 ; if same model not available but pcs made by same manufacturer available: .3 ; by other manufacturers: .1)?

Any help will be greatly appreciated.

Thanks,
Jojy
