I would like to update new records that get inserted in DataSet to Sql Server Database. Below is a working example of how to do this if you use "DataAdapter.Fill(ds)".
But i don't want to fill data, becouse i don't need data, i only need shema (I will use this dataset to insert new data to Sql), so i would like to use "DataAdapter.FillSchema(ds)"

My dataset table data is from multiple tables (showing on a gridview),How to update the database tables using batch udpate on clicking submit, if the data is from a signle table, no problem, but I am not sure how to handle if the datais from mulitiple tables? If I have related tables, do I need put them in differet tables in the dataset?
View 6 Repliesi have this xml file which i read using the DataSet.ReadXml( path ) method . The tables created from the Xml file is Related in such a maner that each product has many options. Product is in one table and Options are in another.Now all i want to do is display the related tables in One Gridview. For your reference below is the products Xml file,
[Code]....
Now this is what i have done in the Code behind , have a look below
[Code]....
Now the Grid works Great if i want to Display Individual tables out from Dataset but not when they are related . Please do shine your Knowledge on what should be done to display Child ~ Master relationship. By the way , its a definite NO for someone who would show me that link from msdn about displaying XML data using Xmldatasource and gridview [That's a lousy way to display data]
I have a problem in getting my gridview to update. The datasource gets its data from 2 related tables using the following select statement:
SELECT StudentSubject.StudentID, Students.[1stName], Students.Surname, Students.Grade, StudentSubject.Subject, StudentSubject.GradeOverall, StudentSubject.ReportYear, StudentSubject.ReportSession, StudentSubject.Criteria1Grade, StudentSubject.Criteria2Grade,
StudentSubject.Criteria3Grade, StudentSubject.Criteria4Grade, StudentSubject.Criteria5Grade, StudentSubject.Criteria6Grade, StudentSubject.Criteria7Grade, StudentSubject.Criteria8Grade, StudentSubject.Criteria9Grade, StudentSubject.Criteria10Grade, StudentSubject.Comment
FROM (Students INNER JOIN StudentSubject ON Students.StudentID = StudentSubject.StudentID)
WHERE (StudentSubject.Subject = ?) AND (StudentSubject.ReportYear = ?) AND (Students.Grade = ?) AND (StudentSubject.ReportSession = ?)
The ? stem from combo box controls which I use to filter the results So far so good!
However, when I try to update the data in just one of the tables, nothing happens, no error, just no update. The update statement I'm using is:
UPDATE StudentSubject SET GradeOverall = ?, Criteria1Grade = ?, Criteria8Grade = ?, Criteria7Grade = ?, Criteria6Grade = ?, Criteria5Grade = ?, Criteria4Grade = ?, Criteria3Grade = ?, Criteria2Grade = ?, Criteria9Grade = ?, Criteria10Grade = ?, Comment =?
WHERE (StudentID = ?) AND (Subject = ?) AND (ReportYear = ?) AND (ReportSession = ?)
I've tried this with a similar setup with just on table and it works fine.

I am getting Resultset from SQL server2005.It contains 4 tables.

I need to join two tables accross two different databases and return an ADO dataset.
ie: select * from database1.table1 a inner join database2.table2 b on
a.key=b.key where some_condition=true
My main problem is how to specify the SqlCommand parameters specifically the connection string for both databses. Is this possible?
Here's my DB structure:
I have three tables.
User, Details, Optional
User has fields: ID, FirstName, LastName
Details has fields: ID, MyDetails1, MyDetails2, User_ID
Optional has fields: ID, MyOptions1, MyOptions2, User_ID
There is a 1 to many relationship with User & Detail (User ID & Detail User_ID)
There is a 1 to many relationship with User & Optional (User ID & Optional User_ID)
With that said, one user can have many details and/or many optionals
Now I'm trying to build a linq query that will say:
"where user id = x, select FirstName, LastName, all MyDetails1 from every record where User_ID == x, all MyOptions1 from every record where User_ID == x"
After the merge I should have one string that lists the distict user & all of their many fields:
FirstName + LastName + (MyDetails1 + MyDetails1 + MyDetails1..etc) + (MyOptions1 + MyOptions1)
Anyone try this before?
I tried this with JOIN but this doesn't do the trick for what I'm looking for.
So if I had 3 MyDetails records associated with ID == 2, I would get three results like:
John Doe MyDetails_X
John Doe MyDetails_Y
John Doe MyDetails_Z
I'm working with asp.net 3.5 WebForms and LINQ to Entities.
I created the database with their relationships, but when I go to import the data with LinqToEntities, some reports and have not seen any reports 1 to 1.
I can create them after the reports have imported the tables LinqToEntities?
I have two SQL Server tables with Primary Keys (PK) and a Foreign Key (FK) linking the two tables:
1) Table "Order"
OrderID, int, PK
AddressID, int, FK
...
2) Table "Address"
AddressID, int, PK
City, nvarchar(50)
...
Then I've created an (ADO.NET) Entity Data Model out of those two tables. Now on my (ASP.NET) webpage I put a GridView with an EntityDataSource. In my GridView I want to display two columns:
OrderID City (belonging to that order and linked by the AddressID-key) How can I do that? My problem is: When I configure the Entity Data Source I can select an "EntitySetName" which can be either "Order" or "Address" but not both, nor can I select any kind of relationship. If I select "Order" as EntitySetName
then in the GridView I can add the columns
OrderID
Address
Address.AddressID
Adding the column "Address" displays empty cells. Adding "OrderID" and "Address.AddressID" displays the expected IDs. But how can I add the "City" of the related address to my GridView? Edit: Clarification:
The Entity Framework has created a class "Order" and a class "Address" corresponding to the database tables. The class "Order" has a reference to an "Address" object as a navigation property, corresponding to the 1-n relationship between Address and Order table. Basically I want to have a column in my GridView which displays Order.Address.City. I have tried to add a bound field with "Address.City" as data field to the GridView but it results in a runtime error ("no such property...").
Let say you read a customer record into Customer object. Do it read all the related records across tables at the same time Or it only reads when you do from o in customerobject.orders
View 2 RepliesAfter running the aspnet_regsql.exe tool, i notice a bunch of different tables pertaining to the ASPNET security (e.g. aspnet_Applications, aspnet_Membership, aspnet_Paths, aspnet_Personalations, aspnet_Profile, aspnet_Roles, aspnet_SchemaVersion, aspnet_Users, aspnet_UsersInRoles). Do the different providers (AspNetSqlMembershipProvider, AspNetSqlProfileProvider, AspNetSQLRoleProvider) relate or associated with certain aspnet_xyz tables? I imagine the AspNetSQLProfileProvider is responsible for the aspnet_Profile table correct? The AspNetSQLRoleProvider probably is tied to the aspnet_Users, aspnet_Roles, aspnet_UsersInRoles table? Any links documenting the relationship between teh providers and the aspnet_xyz tables?
View 1 RepliesI am using ASP.NET (C# and sql server express 2005) for my web application project. I have three related tables. I want to do an insert using typed datasets,tableadapters and three tier architecture. I wish to know how to do simultaneous inserts in 3 tables. So i wish to insert a row in first table and get its primary key. Same with the second table. I will use the primary keys of those first two tables to do the insert in the third table. How can i accomplish this using formview control and what methods should i use??
View 3 RepliesI 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?
I've created a membership system based on asp.net 2. There are other tables that store user information, such as emails sent etc. I've created a users table based on the TableProfileProvider. My question is concerning deleting the member
Is it OK to delete the member from the aspnet_membership table and roles related tables using Membership.DeleteUser, though keep all the custom tables and the information including the information in the Users table created by the TableProfileProvider? or can you foresee problems?
I have and Article object that I update in my controller.... the object is passed into the controller and then I just call UpdateModel(inArticle) and it was all good. I now expanded my article to belong to a category and want to do that update there as well. I am not sure if it was the right thing to do but just as a start i hard-coded an update to the ArticleCategory table, just after I do the UpdateModel. This works but I am not sure how to code this update?
I am using the repository patter and i somehow feel that I should be passing an Article and an ArticleCategory object from the view to the controller? While I was writing this I thought that I could just extend my article object to include the categoryID but what if I really wanted to pass two un-related objects from the view to the controller? The UpdateModel persistes the database objects as by VoodooMagic, how would it work if I wanted to update 2 un-related objects?

I will be providing a combo box in my application that contains list of student names.How can I link this combo box with the cystal report to dynamically display report for different student on selected index change of combo box?
View 2 RepliesI have 5 tables of which one has a primary key called "pid" as follows in patientdetails table the pid of a patient is used to compare the pid in remaining tables so the data in matching pid records can be stored in dataset. I tried using stored procedure to get them together in one dataset but it just doesent happen. This is my stored procedure,

I think the execution doesent proceed after the first if exists statements, because only the data in patientdetails is stored in dataset. and one more thing. all test tables need not contain a data against every pid in patientdetails table.

I have a C# problem I need to synchronize two MS Access tables from two different databases(two databases over a network) which is quite similar, I thought of using two different OleDbConnections and two DataAdapters to fill a Single DataSet and then manipulate the data in the DataSet, I think the source table (database with the primary data) should be loaded first (into the DataSet) then the secondary table from the remote database should subtract the existing records in the DataSet to get the difference then the difference should be Appended to the remote table, but I don't know how to remove the same records from the DataSet and to send the remaining records to the secondary database.
Here is some code I already have, but I don't know how to get this to work:

I'm trying to use a DataSet to maintain some rows for a table, and when I've finished my changes, send all changes to the database using a SqlDataAdapter.
I find if there are no rows in the table in the database then I am getting a 'Object reference not set to an instance of an object' when I try to access the table in the Dataset.
Is there a way to work with a Dataset like this ie. I start off with an empty table and I wish to add rows, to access the structure of the table rows, build rows, then add them and do the update on the SQLDataAdapter.

I have 2 tables in SqlServer 2008.
Table1: T1id, SomeData
Table2: T2id, T1id, SomeData
I am using DataAdapter.FillSchema to create shema of tables in DataSet. I created DataRelation on columns
T1id in both tables.
Now when i try to Update Sql Database T1id in Table2 remains 0 and not the value of T1id in Table1.
I can successfully update Sql Database if i fill DataSet with records first (Using DataAdapter.Fill), but that's not what i want to do. I don't need "old" records in my dataset. I want to use dataset just to store all imputs from user until the proccess is done and then insert all those records "at the same time".
