what is the recommended data access strategy for the following environment: single stored procedure, many parameters, asp.net 4.0, sql server 2008, and the stored proc returns 11 different recordsets, all of which get displayed in various different elements too complex and specific to be handled by server controls.
View 1 RepliesBackground: I use stored procedures exclusively for an ASP.NET application. I am using a DataReader to load a dataset object.
View 4 RepliesWhen can I use Stored Procedure? Is this useful for looping into multiple SELECT statements to return single value? How? Can anyone post some sample codes? I have text query and notice that my web application is slow and want to find ways to speed it up. Is there any possible ways aside from Stored Procedures?
View 4 RepliesI have a small query can we store three different stored procedure data into single dataset (in multiple tables). I am asking this because I have three stored procedure and when I run them simultaneously it takes less time to execute and when I run them separately it takes more time and I want to use all three stored procedure in page load.
Environment - SQL Server 2005, ASP.net 2.0
it's possible to access contrls on aps.net page like textbox from stored procedure in sql 2008.
so I get the value of the textbox on the page direct from stored procedure .
I am trying to return single string result through a stored procedure and Linq. This works fine when I test the stored procedure but it is not returning the value to the page. The value returned is always 0 which is the return value. This is the stored procedure:
ALTER PROCEDURE Login
@CustomerName nvarchar(50),
@Password nvarchar(50) output
As
Select @Password=Password
From Customers
Where Customers.CustomerName=@CustomerName
This is the vb
ALTER PROCEDURE Login
@CustomerName nvarchar(50),
@Password nvarchar(50) output
As
Select @Password=Password
From Customers
Where Customers.CustomerName=@CustomerName is the code created by the designer
This is the designer function
<FunctionAttribute(Name:="dbo.Login")> _
Public Function Login(<Parameter(Name:="CustomerName", DbType:="NVarChar(50)")> ByVal customerName
As String, <Parameter(Name:="Password", DbType:="NVarChar(50)")> ByRef password As String) As IntegerDim result
As IExecuteResult = Me.ExecuteMethodCall(Me, CType(MethodInfo.GetCurrentMethod,MethodInfo), customerName, password)
password = CType(result.GetParameterValue(1),String)
End Function
I get a single value from a stroed procedure of type float. Even if I change it into Int or decimal in the procedure when I call it from my asp.net appliction with ExecuteScalar I get this error:
Exception Details: System.InvalidCastException: Object must implement IConvertible.
Source Error:

I tried with
Int32 pomalor=(int32)distpostSqlCommand1.ExecuteScalar();
= Convert.ToString(...);
= (String).....
but I always get the same error.

I have an application that uses an aps:GridView. The GridView is populated using a DataSource that calls a Stored Procedure. The DataSource passes parameters to the Stored Procedure based on some text fields. The page has been running slower than wanted, so I was doing some checking.
I ran SQL Profiler while loading the page, and saw the Stored Procedure was being called twice. I stepped through the code and found out that in the Page Load Complete event was where this was happening. In this event, I set the value of a parameter for the Stored Procedure, then did a DataBind on the GridView to pick up the data. As I was stepping through the code, I watched the SQL Profiler. When I got to the step of setting the parameter, the Stored Procedure had not yet been called. When I stepped through that and got to the DataBind command (before running that step), the SQL Profiler showed that the Stored Procedure had been called. Then I did the DataBind and the StoredProcedure was called again.
My question is, how do I get the parameters set, and get the GridView data bound, and only call the StoredProcedure once? If I comment out the DataBind step, the StoredProcedure never does get called (which seems really strange to me...).

View 1 RepliesI can return single integer values when using stored procedures with Linq but I cant get single string values returned.
View 2 RepliesHere's a stored procedure I created that uses another stored procedure inside it to return a value:
[Code]....
Note the 'exec dirinfo.dbo.d_searchempbyname @TicketSubName' part. That stored procedure will return a single record. What I need is to get a single column from that recordset (in this case, the email address of the employee), and store that value in a variable.
I tried nested ListViews but can get the display wanted.In my database I have a Category Table and a Product table.They share the CG_ID value.I want to make a stored procedure that will use two select statements to produce a single table.that can be used as a ListView DataSource.

View 1 RepliesI have a stored procedure in SQL server 2000. It is a simple select query and returns a list of account names. However, when I try to execute the stored procedure, it automatically declare @return_value as int and return this int as shown below:
DECLARE @return_value int
EXEC @return_value = [dbo].[p_getAccountNameListByPrefix]
@prefixText = N'br',
@count = 40
SELECT 'Return Value' = @return_value
How can I make the stored procedure return the list of account names as expected?

Initially, I have tried to use stored procedure. But I changed my mind and preferred to call sql query in codebase with command text. However, it stills tries to find initially-called stored procedure (which is neither called or exists).I think that it is related caching. But I tried it with different browsers it did not work.What might be the reason?

I have a table with 4 columns.The first column is a list of teams.The other three columns specify whether the team member with the particular id is present on any particular day .Say for example in the third row the running Team has 2 and 3 which means team member with the id 2 and 3 are present.Multiple values are seperated by the pipe symbol '|'.I have a Query like this
Select Teamname from tblTeam where Running not like '%|2|%' and Running not like '%|3|%' and Running not like '%|7|%' and Biking not like '%|1|%' and Biking not like '%|4|%' and Biking not like '%|7|%' and shooting not like '%|3|%' and shooting not like '%|4|%' and shooting not like '%|7|%' Basically i am searching the columns with like clause.The search criteria for each column may vary.In the above query i am searching for Teams where Running column does not contain 2,3 and 7,Biking column does not contain 1,4 and 7 and the shooting column does not contain 3,4 and 7. I would like to set a stored procedure where i would be able to pass 3 set of parameters from the code behind(I am using VB.net) for Running column search,Biking column search and the shooting column search.
