The correct syntax for returning a DataSet

[martinharvey via DotNetMonster.com]

I realise this is a beginners question but i would be grateful for some help


Untill now i have been using Datareaders for example;

Public Class Catalog
Public Shared Function SP_GetBB() As SqlDataReader

' Create the connection object
Dim connection As New SqlConnection(ConnectionString)
' Create and initialize the command object
Dim command As New SqlCommand("SP_GetBB", connection)
command.CommandType = CommandType.StoredProcedure
' Open the connection
connection.Open()
' Return a SqlDataReader to the calling function
Return command.ExecuteReader(CommandBehavior.CloseConnection)
End Function

Can anyone tell me how to convert the above to return a Dataset
I have got this far but am not sure how to finish:


Public Class Catalog
Public Shared Function SP_GetBB() As System.Data.DataSet
' Create the connection object
Dim connection As New SqlConnection(ConnectionString)
' Create and initialize the command object
Dim command As New SqlCommand("SP_GetBB", connection)
command.CommandType = CommandType.StoredProcedure.........
....................................

many thanks

Hi Martin,

you need a DataAdapter to fill your DataSet, for example:

Public Function SelectSqlSrvRows(dataSet As DataSet, connection As String,
query As String) As DataSet
Dim conn As New SqlConnection(connection)
Dim adapter As New SqlDataAdapter()
adapter.SelectCommand = new SqlCommand(query, conn)
adapter.Fill(dataset)
Return dataset
End Function
