vba增删改查数据库

你在EXCEL中增加一个列名为ID,后在VBA中写以下代码，并引用Microsoft ActiveX Data Objects 2.8后执行
Public Sub 写入SQL2008()
Dim cnn As New ADODB.Connection
Dim SQL As String, mydata As String, mytable As String
Dim i%
mydata = "KKKK" '指定要修改的数据库
mytable = "aaaa" '指定数据表
'建立与指定SQL Server数据库的连接
cnn.ConnectionString = "Provider=SQLOLEDB;" _
& "User ID=sa;" _ 'sa改成你SQL账号(通常不用改)
& "Password =123;" _ '123改成你SQL2008密码
& "Data Source=sowin;" _ 'sowin改成你的SQL2008的电脑名,
'如sql2008在网络上，则sowin改成IP地址(如192.168.0.1)
& "Initial Catalog =" & mydata
cnn.Open
'查询全表某些字段的记录
for i = 2 to [a65536].end(xlup).row
SQL = "UPDATE " & mytable & " SET x=" & cells(i,1) & "," & _
"y=" & cells(i,2) & "," & _
"z=" & cells(i,3) & "," & _
"where id=11"
next i
'注意引号里面的空格
'数据库没有更新的数据则用INSERT INTO
'SQL = "INSERT INTO " & mytable & " COLUMNS(x,y,z)" & _
" VALUES('" & CELLS(i,1) & "','" & cells(i,2) & "','" & cells(i,3) &"')"
cnn.Execute(SQL)
cnn.Close
Set cnn = Nothing
End Sub
