using sql server 2005 and vb.net 2005. I am writing a console application to import a mass amount of data from a non-sql database table into a sql server database table. The destination db table (sql server) has fewer tables than the source db table so I need to map the columns. does anyone have an example of how to do this?
View 1 RepliesWhat would you all suggest a database with less number of tables and more number of columns or more number of tables with less number of columns. I am developing a web application using Visual stuio 2005 and Sql Server 2005
View 2 RepliesI have two sql tables.
- (Fields:PersonID, FirstName, LastName, Role, Department)
and
- (fields: PersonID, Unit).
I want to merge those with a single table ( Fields:PersonID, FirstName, LastName, Role, Department, Unit). How can I query to accomplish this so that same personID data go to same row ? ANY QUERY ?? (I have an idea : both export to excel and merge into a single excel file and import to SQL table but due to very long data it was truncated last time when importing so I don't want to reimport again.)
I am developing the Home page of a Client. Apart from various things on this home page I have a text box and search button. Having said that, I have a database in which I have almost 12 tables with varying number of columns.

View 2 RepliesI have an ASPNET application written in VB.NET which resides on the company's intranet. I am trying to do a bulkcopy from an excel file which is located in a secure folder on the web server to an existing table in Sql Server. The problem is that the folder requires a user name and password which is not the current logged in user or the ASPNET user. My question is how do I logon to the folder so that I can access the Excel file.
View 2 RepliesI have a partitioned db where several tables have the exact same structure. I'm able to query the tables using linq, but only by quering the individual tables 1 at a time and by using the explicit table name. For example at the moment, I have 8 tables so I have something similar to the following:
[Code]....
Is there any way, that based on a certain value (stringValue), I could determine which table to query and then code the linq query just once?
is there an easy way to compare two columns in two datatable to see if they match? I need to check if the values in column["x"] of datatable1 occur in column ["y"] of datatable2, without iterating through both tables (for each value in column of dt1, check column of dt2). I tried:
foreach (DataRow dr in dt1.rows)
if (dt2.rows.find(dr["x"]) but this checks the whole row and if finds an "x" in any column, "if" condition is true. I need to only check one column of dt2. Tables have different columns but the same primary column and that's what I need to check
I have two tables:
Entity
ID (PK), int
Name
Descrip
Users
ID (PK)
EntityID, int (this is not connected to Entity table)
Now I am using LINQ to pull the records which has a Entity.ID = something. Which will show me couple of records in my GridView. Here is my LINQ statement:
protected void Page_Load(object sender, EventArgs e)
{
string getEntity = Request.QueryString["EntityID"];
int getIntEntity = Int32.Parse(getEntity);
OISEntityTestingDataContext db = new OISEntityTestingDataContext();
//OISLinqtoSQLDataContext db = new OISLinqtoSQLDataContext();
var tr =
from r in db.Users
join s in db.Entities on r.UserID equals s.ID
where s.ID == getIntEntity
select new
{
//To Show Items in GridView!
};
GridView1.DataSource = tr;
GridView1.DataBind();
}

This is the code which I am using for altering the number of columns in a table in the DB. so with this code i am able to add new coulmns dynamically. Now my major requirement in this is to obtain the headercount from the user( say "telephone number" and "language") and based on it generate the columns dynamically in the table in the DB.

How to create a table which is the combination of different columns in database tables.
I know how to make the var table using single table.
What is I have to combine multiple coolumns and create a table.
My requirement is a gridview which has a datasource which is loading from columns from multiple tables.
I am trying to create an application in which there is a summary of outstanding payments.
One table is Table_Bills.
The other table stores records of Payments made and is called Table_Payments.
In summary i want to show 3 figures - each in separate one field datagridview with a data_source in separate data_adapter:
1) Ammount_Due 2) Amount_Paid 3) Balance.
The first two are no problem but the last is giving me a headache.
I tried this:
SELECT SUM(DHB_New_Jobtable.DayWage) - SUM(DHB_Payments.Ammount) AS Expr1
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...").
I want to hide all FK Columns in all tables. I am using Asp.Net Dynamic Data 4.0.
I tried to use this code:

And then in List page template call:

But this does not work. If I set breakpoint in function GenerateFields it newer stops there.
