想必大家都很喜欢用Word打字,用Excel进行计算和规划,用PowerPoint作幻灯片进行展示…,但是这只用到了Office系列产品的很少的一部分功能。据调查,绝大部分用户只用到了Office产品的20%的功能,很少有人注意到Visual Basic for Application。实际上,熟悉掌握VBA的功能可以使你的工作事半功倍,尤其对会计、金融等专业来说,作出一套好的宏,几乎可以作到一劳永逸!最近,AutoCAD中也加入了VBA的功能,这不能不说这是一个趋势!
VBA的功能决不只是让病毒制造者用来制造麻烦的,VBA能被用来制造病毒的同时也正说明了其功能的强大与易用!利用ADO对象,可以很方便的进行数据库操作!下面就是一个简单的数据交换的例子:
由于ADO对象不直接支持MySQL,所以必须先安装MyODBC, 后者也是一个免费产品,在www.mysql.org上有下载,安装好了MyODBC, 就可以在ODBC数据源管理中配置一个数据源名称,把它指向你想连接的MySQL数据库。代码如下:
Sub connectMySQL()
'通过MyODBC去连接MySQL数据库,并将Microsoft SQL Server 7
'的数据转进mysql中
Dim sConnect As String, sSql As String, i As Long
Dim cnMSSQL As New ADODB.Connection
Dim cnMySQL As New ADODB.Connection
'声明并创建对象 连接
Dim rs As New ADODB.Recordset '声明并创建对象 记录集
Dim cm As New ADODB.Command '声明并创建对象 命令
sConnect = "dsn=mysql1" '指定MySQL的数据源名称
cnMySQL.Open sConnect '连接到 mysql
sConnect="Provider=SQLOLEDB.1;Persist Security Info=False;User ID=sa;pwd=123456;Initial Catalog=softdown;Data Source=ntserver"
'连接到 ms sql server 7
cnMSSQL.Open sConnect
'sSql = "create table softinfo (softNum smallint,softname varchar(70),softdesc blob," & _
"softpath varchar(30),softleng varchar(10),softclass varchar(10),softsugest tinyint(1)," & _
"softdown smallint(4))" '创建新的MySQL数据表语句
sSql = "select * from softinfo order by softnum"
rs.Open sSql, cnMSSQL, 1, 1
While Not rs.EOF
sSql = "insert into softinfo values (" & Trim(rs(0).Value) & ",'" & Trim(rs(1).Value) & _
"','" & Trim(rs(2).Value) & "','" & Trim(rs(3).Value) & "','" & Trim(rs(4).Value) & _
"','" & Trim(rs(5).Value) & "'," & Trim(rs(6).Value) & "," & Trim(rs(7).Value) & ")"
cm.ActiveConnection = cnMySQL
cm.CommandType = adCmdText
cm.CommandText = sSql
cm.Execute
rs.MoveNext
Wend
rs.Close
Set rs = Nothing
cnMySQL.Close
Set cnMySQL = Nothing
cnMSSQL.Close
Set cnMSSQL = Nothing
End Sub
