After creating a dataset, which has CRUD statements generated two or more tables, which Data Control should I use that will allow me to insert data into fields into 2 or more tables from a single web form. I'm trying to create a web form that will allow the user to input student information, such as general information, medical information, etc.
View 3 RepliesI'd like to build an Asp.Net website using the .net 3.5 framework. I have a SQL Database called "Database.mdf"
View 1 RepliesI have a stored procedure that returns 3 tables within the single recordset it returns. If I set a SqlDataSource to get data from this procedure, it works, but it only returns the first table. I want to have a GridView display the data from the 2nd or 3rd table using a SqlDataSource, but I can't figure out how to specify a particular table.
While there are some posts discussing this out there, I can't get a definitive answer about whether or not this is even possible (?). In a worst-case scenario, I can create another SP that only returns the 3rd table - but that creates a little maintenance headache that I would prefer to avoid.
I a problem defining the variable @Bestilling in the codeBehind for adding the record to the database using a single form page. The database design with corresponding form are as below:
My ASPX.CS:
private void GridView1_BindData()
{
SqlConnection conn = new SqlConnection(connStr);
SqlDataAdapter dAd = new SqlDataAdapter("SELECT kart_DemoOrder.OrderID,
[Code]....
I get error in the method: "GridView1_AddNewRecord".
Must declare the scalar variable "@BestillingID". Is there a way to use only one Add Method and not two as I did?
So I have two tables in my database, Contacts and Addresses:
Contacts : ContactID | AddressID | FirstName | LastName
Addresses: AddressID | Address1 | Address2 | City | State | Zipcode
I have a page where you can add a contact. It contains all the information for a contact and an address for a contact. Here's my code for when you submit the form:
[code]...
Now my main concern is that the address is added successfully, but then an error occurs when I try to save the contact, leaving the address in the database with no contact.
What's the best practice here for rolling back any changes if an error occurs?
I am having a hard time solving the following with an MVC view. My goal is to display data from multiple tables in a single MVC view. The bulk of the data comes from a table called Retailers. I also have another table called RetailerCategories which stores the retailerid from the Retailers table and also a categoryid linking to a Category table. Note that there are multiple records for each retailerid in the RetailerCategories table.
In the view I want to show a list of retailers and with each retailer I want to show the list of categories applicable to them. What would be the best way to accomplish this?
I have hard time trying to find the solution to retrieve data from multiple tables in one database.
table Kategorije has fields: idKategorija, naziv, opis table Clanak has fields: idClanak, idKategorija, naslov, autor,...
Kategorije.idKategorijais joined with Clanak.idKategorija, but that isn't the solution because I want my web site to show the Kategorije.naziv instead of Kategorije.idKategorija. This is the code I'm currently using to get idKategorije shown on my web site:

View 2 RepliesI am writting a directory website that advertises fitness classes. These classes are listed by Class Type, and Geographical Area. Each Class Type can satisfy one or more of four Fitness Goals such as Loose Weight etc...
I have a table for Classes (classid, classname, classdesc, classtypeid, geoareaid) I have a table for geographic areas (geoareaid, geoarea) And I have a table for ClassTypes (classtypeid, classtypename, classtypedesc)
Which obviously links geographic area via the classes.geoareaid as a forgien key and classtypes by classes.classtypeid as a forgien key.
I can list all classes by type and also by geo area no problem, the problem arrises when I then also want to filter by goal.
The Goals Table (goalid, goal, goaldesc) is linked to the classtypes table via another table classtypes_goals (classtypeid, goalid) as each classtype can satisfy any of the 4 goals.
I am using a DataSet to fetch the data from a Stored Procedure in the SQL Database but because the classtypes can be linked to multiple goals I am getting duplication in my list depending on how many goals a classtype satisfies.
All I need in my data list is class name, class type and area I don't even need to display the goal I just want a drop down above the table that will filter the list and show only classes of classtype that satisfy the goal chosen.
I'm looking for ideas on deleting data from the multiple SQL tables with LINQ (C#).
My existing solution does the following:
1. DeleteAllOnSubmit( Subset of the data from the child table)
2. DeleteAllOnSubmit( Subset of the data from another child table)
3. DeleteAllOnSubmit( Data from the parent table)
4. CommitChanges()
All this resides within a single method, which makes it ugly and not re-usable.
I have considered the following alternatives, but I decided not to use them:
1. Cascade delete on the tables.
2. Do a join on all tables from which I will remove the data, but I'm not sure yet whether I could pass a join query to DeleteAllOnSubmit().
3. Write stored procedure(s) to delete data from each table. I don't have the time to implement this due to a large number of tables and the time constraints.

I'm building a registration page. The form will insert into multiple table at the same time. I need to automatically get the data from one of those tables and insert it in a field into another 2 tables.
Tables:

As can be seen both the tcoach_Members and tcoach_Roles table have a column named UsersToRolesId; this column is a foreign key to the UsersToRoles table.
In the UsersToRoles table the Id "Is Identity" and increments by 1 automatically. The UserName and the RoleName will be entered into this table upon registration of a user. Following this, in the Roles and Members tables, this Id number must be entered.
The question is, how can I grab this Id number from the UsersToRole table and insert it into both the Roles and Members tables, via code behind? Can anyone advise me of a way to do this?
The code below is what I've done so far but I am stuck at this Id number:

How to insert a multiple records under the single query?
I have a question which is insert multiple rows in a single insert? Is that possible?
For example:
INSERT INTO EMPLOYEE(NAME, AGE)
VALUES
(JAN, 18),
(JEN, 20),
(JIN, 23)
Using C#
I have code, something like I ask but there's an error.
Here's the code
string sql = "INSERT INTO EMPLOYEE(NAME, AGE) VALUES";
for(int i = 0; i < data.length; i++)
{
sql += "(@name" + i.ToString() ", @age" + i.ToString() + "),"
}
sql = sql.Remove(sql.Length - 1);
cmd = SqlCommand(sql, con);
cmd.ExecuteNonQuery;
I got an error of "Fatal error encountered during command execution."
The error goes here
{"Parameter '@name0' must be defined."}
Im struggling with a way to bind multiple rows of sql data to specific controls, what im trying to acheive is having a list of questions / answers in my SQL db and loading them into my web form to build a questionaire.
The data i load into the form depends on criteria like which questionaire is it (there will be 2 seperate ones) and what language should it be loaded in, this will be controlled using drop down lists and passing these parameters to the SQL select statement.
The problem i have is i am unsure which method to pull the data out of the question column in my table, and bind it to seperate controls row by row, should i use a SQLDataReader or load the data into a dataset, or run a stored procedure to pull the data?
Which is the best way to get data from sql and bind it to controls in this situation?
For example:
label1.text = sqlcolumn1.row1.value;
label2.text = sqlcolum1.row2.value;
Etc...
Environment: C#, ASP.NET 4.0, SQL Server 2008.
Here's the scenario: Buyers and Sellers (where all of the sellers have a unique D&B number).
I'm catering to the buyers, and I want them to be able to import a list of sellers based on the D&B number.
Here are the tables:
BuyersSellers - unique list of sellers - one record, no matter how many buyers work with them.BuyerSellers - lookup table - buyer_id, seller_id sets which buyers work with which sellers
ImportedSellers - temp table that holds sellers the buyer wants to add.AllSellers - master table that has all known sellers with D&B numbers (remote database).
Here's the process:
Buyer uploads list of new sellers, they get added to ImportSellers tableMatch ImportedSellers against AllSellers (valid), ignore unmatched (invalid).Add valid ImportedSellers to the Sellers table if they don't exist.Create BuyerSeller records for all valid ImportedSellers - using data from AllSellers.Delete all valid ImportedSellers, leave the unmatched behind so they know what they need to fix.
I've got the upload and import working, but now I'm a little stuck on how to do all of the matching and inserting, and do it as quickly as possible.
I have a sproc that will insert a new record into Table1. Next I need to Insert into another table the scope_identity of the inserted record. How do I incorporate the scope_identity value as the insert parameter in the second insert statement?
View 3 RepliesI've got 3 tables.
Table A: UID, Name

View 7 RepliesI have a dataset with 3 tables that are inner joined. Thsi dataset is connected to an object datasource which is connected to a gridview. So at runtime it displays data from the database. The problem is when I click on a save button to add information to the database it throughs me an error saying Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints. But if i have two tables in my dataset it works 100%. But the problem i need that 3 tables in order to pull the required information. And if i populate the gridview using code to select the information from the database and insert information it also works 100%.
