Verbatim - Why Write @ Before Sql Queries - Select Data From Database Then Write Query?
Oct 1, 2010Suppose we want to select the data from the database then we write the query for that. Example:
SqlConnection con=new SqlConnection(Connetion name) string selectPkId = @"SELECT PK_ID FROM TABLE" SqlCommand cmd=new SqlCommand(selectPkId ,con);
So,my question is that why we basically use @ before the sql query.If I don't use @ before that then it again work fine (does not give any error), then what is need of using "@"?
SQL Server :: Method For Select And Non Select Queries?
Jan 23, 2011I am moving to the world of ASP.NET from an Access VBA / VB6 background and having read a few books on the subject I am still confused about communicating with SQL server in VB with ASP.NET.
As a very quick explination I am used to communicating with the server by passing strings containing the data I want to write (or read) such as:
[Code]....
I do not seem to be able to work out from ALAX, Dynamic Data, Bound Controls, DataViews, connecting to services with SOAP, DataSources and all of the other methods of database communication in ASP.NET which is the right system to do the simple reads and writes in SQL that I want to do.
At present I have a page with all of the controls on it required to collect a block of data I want to insert, it is all now fully validated but although I can build the SQL INSERT command in a string I cannot figure out how to fire it over to the local SQL Express server. Am I even doing this correctly or do I need to look at other controls?

MVC :: Select Data And Display It From Two Tables?
Mar 28, 2011I really have no idea what i am doing here, but all I want to do is display a one to many list from two tables in the database in a view.
I have a ChartController with the following code:
public ActionResult ChartCategoryOne()
{
var chart = from e
in db.PTP_Exercise
[Code]....
Now I need a view. The view that VS2010 creates via the PTP_AthleteExerciseResult model looks like just what I need. But I get the following error:
The model item passed into the dictionary is of type 'System.Data.Entity.Infrastructure.DbQuery`1[PersonalTrainerPro.Models.PTP_Exercise]',
but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable`1[PersonalTrainerPro.Models.PTP_AthleteExerciseResult]'.
I'm not sure why it is passing PersonalTrainerPro.Models.PTP_Exercise, which is one of my automatically generated models derived from the database in the edmx and I have no idea how to set it up to pass IEnumerable instead of DbQuery. I actually have no idea what it means or even if I'm heading in the right direction.

ADO.NET :: Linq To Sql Determine Which Tables To Write?
Sep 9, 2010I was wondering how Linq to Sql determines which tables to write to when given primary/foreign Key relationships. I can (hopefully) better explain using an example. I have the following tables:
Customer CustomerStatus CustomerType CustomerAddresses
Therefore I have a Customer Entity, a CustomerStatus entity, a CustomerType Entity and a List of CustomerAddresses. In my code, I load up the Customer Entity and the List of CustomerAddresses because that's all I need. For some reason Linq to Sql is trying to insert a new Customer Status record. I have no idea why its doing this.
Can anyone please explain to me how linq to sql determines which table(s) will be written to based on the entities above?

SQL Server :: Select Statement For Multiple Tables
Oct 1, 2010SELECT u.Email FROM UserProfiles p, aspnet_Membership u WHERE p.RulesCheckBox = 'True' AND u.UserId = p.UserId This gives me a list of registered member email addresses that have selected the RulesCheckBox in their profile, so I can email them with an email script. There is a relationship between the Membership table and the UserProfile table, so it finds the email addresses from the Membership table where that user has the RulesCheckBox checked in their profile (in UserProfiles table). I'm wanting to add some additional names to this list, from a different table. The purpose is so I can manually add email addresses to the additional table, so the additional email addresses will also receive the same email, even though they aren't registered members of the site. So how can I adjust that SELECT statement so this one is combined with it somehow?:
SELECT Email FROM ExtraEmails WHERE Rules = 'true'

DataSource Controls :: Count From Several Tables In One Select Statement
Mar 14, 2010I am trying to count records belonging to a certain person in three different tables in a single select statement. The database looks like this:
Player
-PlayerId
-Name
Game
-GameId
-TournamentId
...
Goal
-GameId (FK->Game.GameId)
-PlayerId (FK->Player.PlayerId)
-Assist (FK->Player.PlayerId)
Card
-CardId
-GameId (FK->Game.GameId)
-PlayerId(FK->Player.PlayerId)
I want to select the number of goals, assist and cards a player has in a specific tournament. I tried with this query but then the goal and card column shows the sum of the number of rows matching the playerid in the Goal table and the Card table...For example if there is two matching rows in the goal table and three matching rows in the card table, I get 5 in both these columns in the resultset.
