Assembly: System.Data (in System.Data.dll)
Cannot execute a command within a transaction context that differs from the context in which the connection was originally enlisted.
When the CommandType property is set to StoredProcedure, the CommandText property should be set to the name of the stored procedure. The command executes this stored procedure when you call ExecuteReader.
The following example creates an OleDbCommand, and then executes it by passing a string that is an SQL SELECT statement, and a string to use to connect to the data source.
Public Sub CreateReader(ByVal connectionString As String, _ ByVal queryString As String) Using connection As New OleDbConnection(connectionString) Dim command As New OleDbCommand(queryString, connection) connection.Open() Dim reader As OleDbDataReader = command.ExecuteReader() While reader.Read() Console.WriteLine(reader(0).ToString()) End While reader.Close() End Using End Sub
