I am using ASP.NET 2.0 and C#, SQL Server 2005. I am passing parameter to a stored procedure. The parameter is the ProductId. I have 3 types of productId. ProductId 11,0,12.
If the ProductId is zero, I want to pass the productId as 11 to the parameter.
Is this correct way to perform:

I have a GridView and I want to add some more parameters to the DataSource. One of the parameters is called symbols and is a DataTable, and I'm not sure how to add it. Here's my GridView:
<asp:GridView
ID="grdTrades"
runat="server"
DataKeyNames="tradeId"
DataSource="srcTrades"
EnablePersistedSelection="true"
AllowPaging="true"
AllowSorting="true"
PageSize = "10"
AutoGenerateColumns="false"
[Code]....
I did try and bind the data myself and removing the ObjectDataSource entirely but then the sorting and paging events weren't handled.
need a Stored Procedure with a where with 23 where items.But if a item is 0 then i should skip that selection.So i need something like the code below, but sadly that doesnt work... And 23x23=529 selections isn't a option for me.

I am going to insert Multiple record IN sql using storedProcedure from gridview...
for this purpose i am using cell concatinating method and send whole gridview cell data in string variable.
i have tried xml document method or sending data in table through looping as well but didn't satisfy from both of them... b/c concatinating method required a delimeter for seperation(for which i have restrict the user from that sepereator ) and xml method required an extra file which is not a efficient approach .
I have a SP db.sp_GetProfitMatrix , it takes nullable integer parameters, for which I have a default . It refuses me when I try to pass a null value (the two date parameters are nullable in the Linq designer) I get {"Nullable object must have a value."} error. here is my code:
int? nlDt = null;
var pms =
from p
in db.sp_GetProfitMatrix( nlDt.Value, nlDt.Value)
select
new
{
p.Volume,
p.GrossSales,
p.NetSales,
p.COGS
};
I have a CheckBoxList that I need to get the values from, concatenate, and pass into a stored procedure in SQL Server 2005 utilizing Visual Basic. Due to the way our data layer is I cannot use a SqlCommand object at this level.
I have no problem getting to the selected values in the CheckBoxList:
Dim selectedValue As New StringBuilder
For i = 0 To cblMethods.Items.Count -1
If cblMethods.Items(i).Selected Then
selectedValue.Append(cblMethods.Items(i).Text)
End If
Next
The problem is that I do not know how to list the values in such a way that my stored procedure will pull data:
SET @MethodNames ='GetWords','GetLetters'
SELECT * FROM TABLE WHERE method IN ( @MethodNames )
I've tried experimenting with apostraphes but cannot make it work:
selectedValue.Append("'''" + cblMethods.Items(i).Text + "''', "
- When I execute my query within Enterprise Manager giving the "Country" parameter a value of US, it returns the expected records
- When I assigned that value either programmatically or within the SelectParameters of my SqlDataSource, no rows are returned at all...
I have this as a parameter in the sproc:
@Country char(2) = NULL
and the relevant WHERE clause entry is:
AND (@Country IS NULL OR a.CountryCode = @Country)
My SelectParameter is:
asp:Parameter Name="Country" />
I've tried adding the "DefaultValue" property set to "US" and also tried setting it as sds.SelectParameters[4].DefaultValue="US"
When I do either of these things I get no records returned...

View 10 Replieshere is my code for selectiong some records from db table
string strSql = "select * from mtblNBD where SentTo=@SentTo and InternalStatus Is NULL order by DeadLine desc";
SqlCommand com = new SqlCommand(strSql, con);
com.Parameters.Add("@SentTo", SqlDbType.NVarChar, 50).Value = (string)Session["uname"];
here I am using parameters for SenTo field but not for NULL so it is ok... or should I use parameters for this field where value is NULL , if yes then how can I use parameter for this

How could I add parameters on dataadapter? I tried
[Code]....
But parameters is unknown for dataadapter.
I have asked similiar question before where I have two control on the page header says "username" and "gender". User can select both the control or either one and the page will execute searching based on the criteria supplied. So if username supplied
SELECT * FROM [this_table] WHERE username = @username
and if gender supplied
SELECT * FROM [this_table] WHERE gender = @gender
and if both supplied
SELECT * FROM [this_table] WHERE username = @username AND gender = @gender
I know this sounds not very complicated but in my case, I am having like more than 10 controls up there. It is something likeusername, gender, age, date of brith, title, father name, frst name, last name, blur blur blur and it's a lot then I started to lost. if i were to use if else caluse on code-behind and produce query, it would end up writing a lot of if-else and if i use stored procedure (with if-else) then my stored procedure would contains a lot of if-else statement. I am fairly new to this concept and if I'm on the wrong track, please correct me. Is there any better way to save my hair without actually going through each
if-else statement to build the query ?p.s. I'm using GridView and SqlDataSource command to display the result back on .aspx page.
I have webform with a listview control on it that uses 2 date values supplied by the user (via 2 text boxes) to dynamically set date range parameters for the datasource. The user enters two dates and clicks a button that runs the following code that sets the parameters:
[Code]....
This code works the first time the user clicks the button. But if they change the date values and try again, it only returns the result set from the first request. The parameters are not updated to the new values supplied by the user.
I am trying to check whether a username exists in my database before inserting the new row & display a message to the user if it does.
On my SqlDataSource my InsertCommand looks like this:
InsertCommand="IF NOT EXISTS (SELECT * FROM Users WHERE UserName = @UserName) BEGIN INSERT [Users] ([UserName], [FirstName], [LastName], [City], [State], [Country], [CompanyName], [Active], [PasswordHash]) VALUES (@UserName, @FirstName, @LastName, @City,
@State, @Country, @CompanyName, @Active, @PasswordHash) END"
This works as expected: If the username is unique, the row is created.
If the username already exists, the row is not added.
The problem is, if the row already exists, the insert is rejected but the user is not notified.
So my question is, is there a way I can notify the user?
Maybe something like: InsertCommand = "If Not Exists (select....) Begin Insert...Else Notify User Somehow End This is a basic database, I'm not using the built-in membership provider nor will be.
I'm linking a form to sql database, As far as i know for textbox the code will be like this one below in VB:

I can't see what I've missed

I followd Brian Orrell LINQ tutorial for paging/sorting and created a gridview bound to an ObjectDataSource through a method call which gets data from adatabase. My form includes two buttons with a textbox next to each one of them. I need to be able to populatte th egridview depending on the button that was pressed, I cannot figure out how signal my method which button was pressed.

I have a ListView that, among other things, in the EditItemTemplate, has a pair of related DropDownList controls, sort of a parent/child relationship. The selected value of the parent is used as a parameter for the SQL Datasource of the child. Outside of a control such as the ListView, this would be easy and I'd simply set up a ControlParameter for the SQL Datasource and life would be good. Within the DataList things are not quite so simple. My plan is to set the parameter of the child in the Selecting handler of its datasource. I have hard coded some values and this works the way I want it to. My problem is getting the "parent" value. I've got two theories on how to get this:
#1, I've tried instantiating the parent DropDownList but it is either not available at this point in the page life cycle or I just don't know the syntax to get at it from within the Selecting handler.
#2, I'm thinking I may have to grab the value from the underlying data for the ListViewRow that I am editing, but again, I do not know the object model well enough to get at those values.
Below is a code sample for option #1. As stated, setting the parameter works, but getting the value of the DropDownList does not.
All control are not listed in dropdown when selecting a control for adding parameter to update query.

Ive passed in '02/06/2010' as the date, in the database, the Startdate column has several values of '2010-06-02 13:08:50.503' so I guess its not being found because of the time part. Whats the best way to make sure that I retrieve the correct data ? Im not concerned about the time at all, I just need all rows for 02/06/2010.
getting the Parameters declared in an sql function in the C# code. We can actually get the parameters from a Stored Procedure by giving SqlCommandBuilder.DeriveParameters
Similarly is there any way to get the Parameters from the SQL Function.
