从 EXCEL 连接到 SQL 数据库

Question

我已经学习了一些教程，但我的连接一直失败，我尝试了很多不同的连接方式。

我通过 mySQL 工作台连接到 mySQL。我使用 IP 地址和端口号，然后使用我的凭据登录。这很好用，我可以做我需要的查询。

我现在正尝试通过 Excel，最好是通过 VBA 访问这个数据库。我试图创建一个新的连接，但我所做的一切似乎都不起作用。我不确定将什么放入我的 strConn 字符串中。

我目前正在使用：

Options Explicit
Private Sub CommandButton2_Click()
    Dim cn As ADODB.Connection
    Dim rs As ADODB.Recordset
    Dim strConn As String

    Set cn = New ADODB.Connection
    strConn = "DRIVER={MySQL ODBC 5.3.7 Driver};" & _ 
              "SERVER=XXX.XXX.X.X;" & _ 
              "PORT=3306" & _ 
              "DATABASE=cahier_de_lab;" & _ 
              "UID=xxx;" & _ 
              "PWD=xxx;" & _ 
              "Option=3"

    cn.Open strConn

    ' Find out if the attempt to connect worked.
    If cn.State = adStateOpen Then
          MsgBox "Welcome to Pubs!"
    Else
          MsgBox "Sorry. No Pubs today."
    End If

    ' Close the connection.
    cn.Close

End Sub

感谢您的帮助！

从 Excel 导出到 SQL Server。

Sub InsertInto()

'Declare some variables
Dim cnn As adodb.Connection
Dim cmd As adodb.Command
Dim strSQL As String

'Create a new Connection object
Set cnn = New adodb.Connection

'Set the connection string
cnn.ConnectionString = "Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=True;Initial Catalog=Northwind;Data Source=Excel-PC\SQLEXPRESS"
'cnn.ConnectionString = "DRIVER=SQL Server;SERVER=Excel-PC\SQLEXPRESS;DATABASE=Northwind;Trusted_Connection=Yes"


'Create a new Command object
Set cmd = New adodb.Command

'Open the Connection to the database
cnn.Open

'Associate the command with the connection
cmd.ActiveConnection = cnn

'Tell the Command we are giving it a bit of SQL to run, not a stored procedure
cmd.CommandType = adCmdText

'Create the SQL
strSQL = "UPDATE TBL SET JOIN_DT = '2013-01-22' WHERE EMPID = 2"

'Pass the SQL to the Command object
cmd.CommandText = strSQL


'Execute the bit of SQL to update the database
cmd.Execute

'Close the connection again
cnn.Close

'Remove the objects
Set cmd = Nothing
Set cnn = Nothing

End Sub

Import from SQL Server into Excel . . . . .


Sub Create_Connectionstring()

Dim objDL As MSDASC.DataLinks
Dim cnt As ADODB.Connection
Dim stConnect As String 'Instantiate the objects.

Set objDL = New MSDASC.DataLinks
Set cnt = New ADODB.Connection

On Error GoTo Error_Handling 'Show the Data-link wizard
stConnect = objDL.PromptNew 'Test the connection.
cnt.Open stConnect 'Print the string to the VBE Immediate Window.
Debug.Print stConnect 'Release the objects from memory.
exitHere:
    cnt.Close
    Set cnt = Nothing
    Set objDL = Nothing
Exit Sub

Error_Handling: 'If the user cancel the operation.
If Err.Number = 91 Then
    Resume exitHere
End If
End Sub
