Dim strPath As String = File1.PostedFile.FileName
If strPath = "" Then
Response.Write(
" <script> alert( '请先选择文件 ') </script> ")
Response.End()
End If
'定义连接字符串
Dim sConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & strPath & "; Extended Properties=Excel 8.0;"
Try
Dim oleDbConnection As OleDbConnection = New OleDbConnection(sConnectionString)
oleDbConnection.Open()

'获取excel表
Dim dataTable As DataTable = oleDbConnection.GetOleDbSchemaTable(OleDbSchemaGuid.Tables,Nothing)

'获取sheet名,其中(0)(1)...(N): 按名称排列的表单元素
Dim tableName As String = dataTable.Rows(0)(2).ToString().Trim()
tableName
= "[" & tableName.Replace(" ' "," ") & "]"

'利用sql语句从Excel文件获取数据
Dim query As String = "SELECT 部门,全年任务,本年累计完成,上年同期完成,[完成全年任务的%],[可比增长%] FROM " & tableName
Dim dataset As DataSet = New DataSet()

Dim oleAdapter As OleDbDataAdapter = New OleDbDataAdapter(query,sConnectionString)

oleAdapter.Fill(dataset,
"Rwb")

'sql数据库连接
Dim sqlcon As sqlClient.sqlConnection = New sqlClient.sqlConnection("server=(local);database=test;user id=sa;password=123")
sqlcon.Open()

'从excel文件获得数据后,插入记录到sql Server的数据表
Dim dataTable1 As DataTable = New DataTable()

Dim sqlDA1 As sqlClient.sqlDataAdapter = New sqlClient.sqlDataAdapter("SELECT 部门,[可比增长%] FROM Rwb ",sqlcon)

Dim sqlCB1 As sqlClient.sqlCommandBuilder = New sqlClient.sqlCommandBuilder(sqlDA1)

sqlDA1.Fill(dataTable1)

Dim dataRow11 As DataRow
For Each dataRow11 In dataset.Tables("qssrzb").Rows
'sql里数据dataRow1
Dim dataRow1 As DataRow = dataTable1.NewRow()

dataTable1.Rows.Add(dataRow1)
Next
Console.WriteLine(
"新插入 " & dataTable1.Rows.Count.ToString() & " 条记录 ")
sqlDA1.Update(dataTable1)

oleDbConnection.Close()
Catch ex As Exception
Console.WriteLine(ex.ToString())
End Try
