SELECT 1000000*QuantityNC/Quantity AS PPM FROM [table1] However I need my WHERE clause to do thisI need the above calculation depending on BusUnit, which is linked to PartNumber, which is in the above table. also it has to be by Company (which is selected from a dropdown). And also based on the current month and year.
PartNumber and CompanyName are in [table1]
BusUnitID, PartNumber, SupplierID, are in tblParts
BusUnitID and BusUnit are in tblBusUnits

Suppose 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 "@"?

how to use jquery to write sql queries. consider a webservice call using jquery to asp.net webservice, sending an sql query and getting back the results in json format. but there's a problem with the connection string because it must not be available if a user views the source of the page.

I know there has to be a way to do this but for some reason I keep getting it wrong. I have one query which pulls all of the cities from a zipcode database like so:
[Code]....
Then I have another which counts the records from a transactions table per city, like so:
[Code]....
Only the zipcode is stored in the transactions table, so the idea here is to get a list off all the distinct cities that reside in the state. Once I have the cities, I want a count for each city as a whole, so I need to go back in and get all of the zipcodes that make up one city, and then count the transactions for those zipcodes. It works using the first query above, looping through them and then executing the second for every pass. But shouldn't there be a way to do it all in one query?

I'm currently working on a FOREX Live Trading project that I'm implementing.
I already have a database that stores the CURRENCY PAIR, BUY/SELL, PRICE AND QTY.
But I have a huge problem.
Scenario that is:
A person BUYS EUR/USD at a PRICE of 1.29900 @ quantity 100,000. (This will be recorded in the database table)
Then he BUYS EUR/USD at a PRICE of 1.29950 @ quantity 100,000. (This will then be recorded in the database also)
Then he decides to SELL his EUR/USD at a PRICE of 1.31000 @ quantity 200,000 all out. (How can I check from the database if he previously had make a transaction of BUY/SELL, so that I can do my necessary calculations for the P/L Statement)

I am having trouble with queries because they are not returning the data needed, and I am having trouble figuring out why because I only am testing with 2 records.First I want a query to return all records for one customer as follows:
[Code]....
There are two records with the customerID of 1, but it only returns one,next I try to return only one record, the AccountPrimary or customer_contacts.IsPrimary, but when I add " AND customer_contacts.IsPrimary = 'True' "at the end of my query it then returns both records, but only one IsPrimary = True and the Other = False. Is it backwards? I also tried another method and it returned 30 of the same record and I only have 2

I am planning a project for a pharmacy to enter quality control data to generate reports and graphs with Crystal Reports. There are 20 stores, I need to password protect the entrance page, giving each store their own username and password (just one per store is fine), allowing the store to only access that store's data. Each store will have an associated ID in the MSSQL table.I am using the Membership Provider. I know I need to implement user roles for Managers and Stores levels (Managers can run reports for all stores), I wonder if I can set the default store ID for insert/edit templates after that specific store logs in.Basically, I think I need to filter SQL queries based on the store ID associated with a user ID. I have seen a .NET site that, after logging in, you type in a store id into a textbox, and it gives you access only to that stores data. Something like this would work for my situation.Can anyone explain or show me an example for the best method to accomplish this with C#?

I am working on asp.net 3.5 and in MVC using Linq to SQL classes. In my MVC project i am calling stored procedure using linq to sql that conatin query joining two tables.Below is my code in Partial class
[
Function(Name="dbo.GetUserWiseThreadDetail_SP")]
[ResultType(typeof(Thread))]
[ResultType(typeof(Reply))]
public
IMultipleResults GetUserWiseThreadDetail_SP([Parameter(DbType="VarChar(30)")]
string userID)
{
ExecuteResult result = this.ExecuteMethodCall(this,
(MethodInfo)(MethodInfo.GetCurrentMethod())), userID);
return ((IMultipleResults)(result.ReturnValue));
}
In one of the controller i have made one more class
public class
MypostIndexData
{
public
IEnumerable<Thread> Thrds {
get;
set; }
public
IEnumerable<Reply> Repls {
get;
set; }
public MypostIndexData(IEnumerable<Thread>
thrds,IEnumerable<Reply> repls)
{
this.Thrds=thrds;this.Repls=repls;
}
}
finally coding of controller action method
ForumDataContext pmforum = new
PMForumDataContext();
public
ActionResult MyPosts(string userId)
{
IEnumerable<Thread>thrds;
IEnumerable<Reply>repls;
IMultipleResults result = pmforum.GetUserWiseThreadDetail_SP(userId); (this satement doesnot give any result,if i execute stored proc in
sql it give the results)
thrds = result.GetResult<Thread>();
List<Thread> thrdlist =
new
List<Thread>(thrds);
repls = result.GetResult<Reply>();
List<Reply> replylist;
if (repls !=
null)
{
replylist = new
List<Reply>(repls);
}
return View(new
MypostIndexData(thrds,repls));

I am accepting query/queries from user (our support team) in a text box where user can enter only one query or multiple queries. I need to display result of all queries entered in the textbox. If it is SELECT statement then result of that statement in grid which is done. If UPDATE/INSERT/DELETE then total number of rows affected which is also done but if only one UPDATE/INSERT/DELETE statement is entered in the textbox.
If user enters 2 UPDATE statements and then a SELECT statement then how can I get number of rows affected for individual UPDATE statements just like SQL Server Qury Analyzer displays messages in its result pane.
e.g.
(6 row(s) affected) -- first UPDATE statement
(4 row(s) affected) -- second UPDATE statement
(16 row(s) affected) -- for SELECT statement (grid will also be displayed along with these messages).
I tried almost everything, SqlDataSource (returns count of first statement only), SqlCommand.ExecuteNonQuery and DataAdapter.Fill (returns count of last statement only).

In general terms, which way will require more server processing power and which way will return faster queries... if there is even a difference. The client's database is still on the dev MS SQL server but is essentially but the client has decided they want to collect two more fields of information. Both fields are going to be collection text data and probably varchar(300) will be sufficient for the column data types. Would it ultimately be more efficient to
Add two additional columns in the main table so the data is entered directly into each record, or Add an additional table (or two) with a foriegn key to the primary table that holds the info for each new field The SELECT statement for the main table could be modified to either add the new columns (a.NewColumn1 and a.NewColumn2) or it could contain nested SELECT statements that pull in the data from the other tables. Custom daisy-chained Insert or Update statements would be no problem and a cascade Delete relationship would take care of any deletions. I'm just trying to figure out which would be better from a performance standpoint?

I have a gridview that pulls data from two tables, CLIENT and PAYMENT. I want to add the edit, delete functions to the gridview for the payment portion of the table, that is to edit or delete the payments but not the client. I've manually enabled the edit, delete functions and input the queries. I've also deleted the textboxes from the templates which draw from the CLIENT table so they cannot be edited. Everything looks good on the surface until I actually go to edit or delete anything, and it has no effect.Here's the structure of the two tables:
CLIENT PAYMENT
ClientID Pk PaymentNumber Pk
FName CLIENT$ClientID Fk
LName PaymentDate
ContactNo NULL PaymentAmount
ArrivalDate PaymentDetails NULL
DepartureDate NULL
CurrentResident
Here's the update query:
UPDATE [PAYMENT] SET [PaymentDate] = @PaymentDate, [PaymentAmount] = @PaymentAmount, [PaymentDetails] = @PaymentDetails WHERE [PaymentNumber] = @original_PaymentNumber AND [CLIENT$ClientID] = @original_CLIENT$ClientID AND [PaymentDate] = @original_PaymentDate
AND [PaymentAmount] = @original_PaymentAmount AND (([PaymentDetails] = @original_PaymentDetails) OR ([PaymentDetails] IS NULL AND @original_PaymentDetails IS NULL))
Finally, here's the delete query:
DELETE FROM [PAYMENT] WHERE [PaymentNumber] = @original_PaymentNumber AND [CLIENT$ClientID] = @original_CLIENT$ClientID AND [PaymentDate] = @original_PaymentDate AND [PaymentAmount] = @original_PaymentAmount AND (([PaymentDetails] = @original_PaymentDetails)
OR ([PaymentDetails] IS NULL AND @original_PaymentDetails IS NULL))

1) we have only one select query to select 5 column form the table(i.e. select col1,col2,col3,col4,col5). so in that case should we go for stored procedure Or we can directly write the select query in the .Cs file only ( means in Database layer). when we should go for the SQL server stored procedure and when we should go for in line query in Visual Studio itself.
2)how to decide when to use Clustered and when to use Non Clustered index?

[Code]....
One of the pages works with this code and the other doesn't. The only difference is that the project in which it does work employs a data control tool (ListView) and a custom profile provider.
