如何在 VBA 中使用 ADODB.Connection

要求：

添加以下对项目的引用：

• Microsoft ActiveX 数据对象 2.8 库

• Microsoft ActiveX 数据对象 Recordset 2.8 库

声明变量

Private mDataBase As New ADODB.Connection
Private mRS As New ADODB.Recordset
Private mCmd As New ADODB.Command

创建连接

一个。使用 Windows 身份验证

Private Sub OpenConnection(pServer As String, pCatalog As String)
    Call mDataBase.Open("Provider=SQLOLEDB;Initial Catalog=" & pCatalog & ";Data Source=" & pServer & ";Integrated Security=SSPI")
    mCmd.ActiveConnection = mDataBase
End Sub

湾使用 SQL Server 身份验证

Private Sub OpenConnection2(pServer As String, pCatalog As String, pUser As String, pPsw As String)
    Call mDataBase.Open("Provider=SQLOLEDB;Initial Catalog=" & pCatalog & ";Data Source=" & pServer & ";Integrated Security=SSPI;User ID=" & pUser & ";Password=" & pPsw)
    mCmd.ActiveConnection = mDataBase
End Sub

执行 sql 命令

Private Sub ExecuteCmd(sql As String)
    mCmd.CommandText = sql
    Set mRS = mCmd.Execute
End Sub

从记录集中读取数据

Private Sub ReadRS()
    Do While Not (mRS.EOF)
        Debug.Print "ShipperID: " & mRS.Fields("ShipperID").Value & " CompanyName: " & mRS.Fields("CompanyName").Value & " Phone: " & mRS.Fields("Phone").Value
        Call mRS.MoveNext
    Loop
End Sub

关闭连接

Private Sub CloseConnection()
    Call mDataBase.Close
    Set mRS = Nothing
    Set mCmd = Nothing
    Set mDataBase = Nothing
End Sub

如何使用它？

Public Sub Program()
    Call OpenConnection("ServerName", "NORTHWND")
    Call ExecuteCmd("INSERT INTO [NORTHWND].[dbo].[Shippers]([CompanyName],[Phone]) Values ('speedy shipping','(503) 555-1234')")
    Call ExecuteCmd("SELECT * FROM [NORTHWND].[dbo].[Shippers]")
    Call ReadRS
    Call CloseConnection
End Sub
