ADO.NET :: Converting The Single Value Returned With Stored Procedure?

Mar 6, 2011

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:

[Code]....

I tried with

Int32 pomalor=(int32)distpostSqlCommand1.ExecuteScalar();
= Convert.ToString(...);
= (String).....

but I always get the same error.

C# - Get Column Names From Table Returned From Stored Procedure?

Feb 10, 2011

I have a stored procedure which returns a table. The stored proc is called via a linq datacontext.

It works fine and I get the table back however I really want to also get the title relating to each particular cell returned.

The stored procedure call is like:

var table = DataContext.GetTable().ToList();

So I get a List<GetTable>. The data is fine I just want the column names as well.

DataSource Controls :: Stored Procedure Does Not Indicate Table Returned In Dataset?

Apr 23, 2010

This may not be the correct place to put this as it is both a stored procedure AND Visual Studio 2008 problem.

I have the following stored procedure:

[Code]....

I have been mokeying around with it because of what is happening. I have a dataset, call it dataset1. I drag this stored procedure onto the dataset. I EXPECT a datatable to appear, instead the data set adds this store procedure to the queries table adapter and sets the exec mode to 'NonQuery' which unless I am very mistaken, means "don't expect a dataset back from this' when in fact you DO expect a dataset back from this.

The SQL server is a Windows 2000 Server running SQL 2000. It has never caused us a moments grief since we set it up oh-so-many years ago.

If I connect to a different database and drag a query into the same dataset I get a datatable as I expect. I cannot see where / how this procedure could be wrong. The query when executed returns exactly the data I expect, in the format I expect (looks like a table, acts like a table in the Query analyzer).

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.

Forms Data Controls :: Returning Single String Result Through Stored Procedure

Jun 22, 2010

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)

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?
