[英]VB.NET: How can I use ExecuteSQLCommand and return my data in a datatable and access it?
This is what I'm trying... 这就是我正在尝试的...
Dim myCommand as SqlCommand
Dim myTable as New xsdObject.ObjectDataTable
myCommand = DataAccess.GetSQLCommand( "MyStoredProc", _
CommandType.StoredProcedure, SourceServer.ConnectionLocal)
myCommand.Connection.ChangeDatabase("MyDatabase")
myCommand.Parameters.AddWithValue("@Parameter", DataValue)
ExecuteSQLCommand(myCommand, myTable)
'How to access my data ?
Here is an example without the datatable, as mentioned in your comment. 如您的评论中所述,这是一个没有数据表的示例。
Dim reader As SqlDataReader= MyCommand.ExecuteReader
Dim MyList as new List(Of WhateverObject)
Do While reader.Read
Dim obj as new WhateverObj
obj.Property1 = Reader.GetInt32(0)
obj.Property2 = Reader.GetString(1)
MyList.add(obj)
Loop
reader.Close()
myCommand.Dispose()
For the sake of complete answer that matches the title, with a dataset: 为了使答案与标题匹配,并使用数据集:
Dim Adapter As New SqlDataAdapter(myCommand)
Dim ds As DataSet = New DataSet
Adapter.Fill(ds)
The Datatable: 数据表:
Dim resultTable as DataTable = ds.Tables(0)
要将结果放入DataTable
,您需要围绕SqlCommand
创建一个SqlDataAdapter
并调用其Fill
方法。
