DataSource Controls :: Returning String Value Using Stored Procedure And Linq
Feb 7, 2010I am having problems returning a string value through a stored procedure/linq to a label. Everything works fine if I return an integer value but I cant get a string value to bind to a label. I get the error message
Microsoft.VisualBasic.CompilerServices.Conversions.ParseDouble(String Value,
NumberFormatInfo NumberFormat) +201
Microsoft.VisualBasic.CompilerServices.Conversions.ToInteger(String Value) +66
[InvalidCastException: String "System.Data.Linq.SqlClient.SqlPr" to 'Integer' is invalid‚]
This is the stored procedure
ALTER PROCEDURE test
AS
Select ProductName
From Products
This is the vb page
Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim db As New DataClassesDataContext
Dim product As Integer = db.test.ToString
Label1.Text = product
End Sub
This is the aspx page

Forms Data Controls :: Returning Single String Result Through Stored Procedure
Jun 22, 2010I 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

@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)

DataSource Controls :: Eliminate Returning Of Empty Table From Stored Procedure
Jul 12, 2010I have a Procedure which should return only 1 Record on selecting record according to Priority.
BEGIN
DECLARE @Accounts nvarchar(MAX)
SELECT @Accounts = ISNULL([map_user_modules].[Accounts], '') FROM [map_user_modules]
WHERE [map_user_modules].[id_user] = 231 AND [map_user_modules].[id_module] = 5
IF ((@Accounts = '') OR (@Accounts = 'All'))
SELECT @Accounts = null
BEGIN
Select @@ROWCOUNT as Priority2
END
IF @@ROWCOUNT = 1
BEGIN
Return
END
BEGIN
Select @@ROWCOUNT as Priority3
END
IF @@ROWCOUNT = 1
BEGIN
Return
END
BEGIN
Select @@ROWCOUNT as Priority4
END
IF @@ROWCOUNT = 1
BEGIN
Return
END
In the above statement Suppose we take a scenario where Select @@ROWCOUNT as Priority3 is executed, I get two tables returned, One is the Table returned by Select @@ROWCOUNT as Priority3 and the other is the Table returned by Select @@ROWCOUNT as Priority2 which has no Records. How can I eliminate the Empty table that returns no records.

Feb 23, 2010I have an application where depending on what the user selects run a different stored procedure.
I am using LINQ and am passing the stored procedure name into a sub that will run the stored procedure and return values that I am loading into a DDL.
For example I want to pass the procedure name "GetProducts_Hats" to the sub and not hardcode it.
Protected Sub LoadParamDropDowns(
ByVal SqlObjToExec

I am passing the storedprocedure name in parameter SqlObjToExec
so instead of

I want to code it to be a variable
values = mydb.SqlObjToExec
But the above code does not work.

DataSource Controls :: Execute Stored Procedure Using A String Variable
Jun 22, 2010Is it possible to save execute stored proc command in a string variable and then execute string variable?
Does this logic fits into LINQ2SQL? Why I want to do this - INstead of passing user control references to server, I want to save user control values to string in client side java script and then pass string to server to do actual stored proc execution. Hopefully this will improve performance.
