如何直接从Excel更新Sql表？

Question

我有一个sql数据库，并且能够连接excel电子表格。但是，当我直接从excel更新表时，它并没有更新数据库，并且当我单击“刷新”时，所有输入的数据都不再在excel表中

是否可以在不使用任何查询的情况下从excel更新sql数据库？

Answer 1

有很多方法可以做到这一点。我建议使用类似的方法将数据从Excel推送到SQL Server。

Sub ButtonClick()
'TRUSTED CONNECTION
    On Error GoTo errH

    Dim con As New ADODB.Connection
    Dim rs As New ADODB.Recordset
    Dim strPath As String
    Dim intImportRow As Integer
    Dim strFirstName, strLastName As String

    Dim server, username, password, table, database As String


    With Sheets("Sheet1")

            server = .TextBox1.Text
            table = .TextBox4.Text
            database = .TextBox5.Text


            If con.State <> 1 Then

                con.Open "Provider=SQLOLEDB;Data Source=" & server & ";Initial Catalog=" & database & ";Integrated Security=SSPI;"
                'con.Open

            End If
            'this is the TRUSTED connection string

            Set rs.ActiveConnection = con

            'delete all records first if checkbox checked
            If .CheckBox1 Then
                con.Execute "delete from tbl_demo"
            End If

            'set first row with records to import
            'you could also just loop thru a range if you want.
            intImportRow = 10

            Do Until .Cells(intImportRow, 1) = ""
                strFirstName = .Cells(intImportRow, 1)
                strLastName = .Cells(intImportRow, 2)

                'insert row into database
                con.Execute "insert into tbl_demo (firstname, lastname) values ('" & strFirstName & "', '" & strLastName & "')"

                intImportRow = intImportRow + 1
            Loop

            MsgBox "Done importing", vbInformation

            con.Close
            Set con = Nothing

    End With

Exit Sub

errH:
    MsgBox Err.Description
End Sub

您也可以尝试使用Where子句。

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
