[P][B]方法一：[/B][/P][P]把Excel当作数据库来操作（这样速度快）
或用Excel对象来做，读取数据，然后循环导入[/P][P]读取数据然后一条条的导进去，循环操作因为数据量大很慢。
如何把excel像数据库那样读？难道写成结构体数组么？

End Sub[/P][P][/P][P][B]方法二：[/B][/P][P]EXCEL文件要设置固定格式，还要设置命名范围，然后才可以导入
大致思路如下：
'// 设置打开 EXCEL 文件的连接字符串
strConn = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=excel文件名;Extended Properties=Excel 8.0"
'// 以记录集的形式打开 Excel 文件，adoConn 为 ADODB.Connection 对象
adoConn.Open strConn
'// 将数据插入到指定的表中（以ODBC的方式打开SQL数据库）
strSQL = "INSERT INTO [odbc;Driver={SQL Server};Server=服务器IP;Database=数据库;UID=用户名;PWD=密码].SQL中的表名 SELECT EXCEL中的字段 FROM EXCEL工作表名"
'// 执行导入语句
adoConn.Execute strSQL, , adExecuteNoRecords[/P][P][B]方法三：[/B][/P][P]Dim Conn As ADODB.Connection
Set Conn = New ADODB.Connection
Conn.Open "连接到你的数据库XJGL.MDB的字符串"
Conn.Execute "select * into tmptable from [excel 8.0;database=" + 你的excel表名 + "].[sheet名$]"
Conn.Execute "insert into xsda(学籍号,准考证号,姓名,性别,出生年月,班级)select 学籍号,准考证号,姓名,性别,出生年月,班级 from tmptable"
Conn.Execute "drop tabel tmptable"

本方法采用add添加excel文件和datasheet，然后用save保存。如果用xlApp.Visible=False，则自动生成文件。但是如果文件已经存在，则会弹出是否覆盖的提示。因此，最好先在程序中检查文件是否已经存在，如果存在，则用普通方法打开。如果不存在，则用add添加，并保存。[/P][P][B]vb导出数据到Excel[/B][/P][P]Public Function ExporToExcel(strOpen As String) '入参为SQL查询语句
