如何將多個Excel表導入2個sql服務器表？

Question

我有一個excel文件，其中包含兩個不同的工作表作爲fundmodelrate和project.Now我想要將這兩個不同的表值導入到兩個不同的sql表（k2_fundmodelrate，k2_project）。我只能用1張工作表才能導入和1表，但我想要在兩個表上同時在按鈕單擊事件上導入兩個表值。 我下面的代碼：

private String strConnection = "Data Source=kuws4;Initial Catalog=jes;User ID=sa;Password=******";    
     protected void btnSend_Click(object sender, EventArgs e) 
     { 

      string path = fileuploadExcel.PostedFile.FileName; 

      string excelConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:\fmr.xls;Extended Properties=Excel 12.0;Persist Security Info=False"; 

      OleDbConnection excelConnection = new OleDbConnection(excelConnectionString); 

      OleDbCommand cmd = new OleDbCommand("Select * from [FundModelRate$]", excelConnection); 
      //OleDbCommand cmd1 = new OleDbCommand("Select * from [FundModelRate$], [Project$]", excelConnection); 
      excelConnection.Open(); 
      OleDbDataReader dReader; 
      dReader = cmd.ExecuteReader(); 
      SqlBulkCopy sqlBulk = new SqlBulkCopy(strConnection); 

      sqlBulk.DestinationTableName = "K2_FundModelRate"; 
      // sqlBulk.DestinationTableName = "K2_Project"; 
      sqlBulk.WriteToServer(dReader); 
      excelConnection.Close(); 
     } 

Answer 1

我認爲唯一的辦法是遍歷你的兩個sheets。

看一看This的帖子。這將幫助您獲得sheet的名稱。

當您有sheet名稱時，您可以循環遍歷它們，然後將它們加載到SQL。

也許這可以幫助你：

OleDbConnection objConn = null; 
System.Data.DataTable dt = null; 
string excelConnection = ""; 

if(strFile.Trim().EndsWith(".xlsx")) 
{ 
    excelConnection = string.Format("Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=\"Excel 12.0 Xml;HDR=YES;IMEX=1\";", strFile); 
} 
else if(strFile.Trim().EndsWith(".xls")) 
{ 
    excelConnection = string.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=1\";", strFile); 
} 

objConn = new OleDbConnection(excelConnection); 

objConn.Open(); 

dt = objConn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null); 

String[] excelSheets = new String[dt.Rows.Count]; 
int i = 0; 

foreach(DataRow row in dt.Rows) 
{ 
    excelSheets[i] = row["TABLE_NAME"].ToString(); 
    i++; 
} 

for(int j=0; j < excelSheets.Length; j++) 
{ 
    OleDbCommand cmd = new OleDbCommand("Select * from " + excelSheets[j], excelConnection); 

    excelConnection.Open(); 
    OleDbDataReader dReader; 
    dReader = cmd.ExecuteReader(); 
    SqlBulkCopy sqlBulk = new SqlBulkCopy(strConnection); 

    sqlBulk.DestinationTableName = "YourDestinationTableName"; 

    sqlBulk.WriteToServer(dReader); 
    excelConnection.Close(); 
} 

注：沒有測試

public void importdatafromexcel(string excelfilepath) 
     { 
      //declare variables - edit these based on your particular situation 
      string ssqltable = "test_data";//sql table name 
      // make sure your sheet name is correct, here sheet name is sheet1, so you can change your sheet name if havedifferent 
      string myexceldataquery = "select * from [Sheet1$]"; 
      try 
      { 
       //create our connection strings 
       string sexcelconnectionstring = @"provider=microsoft.jet.oledb.4.0;data source=" + excelfilepath + ";extended properties=" + "\"excel 8.0;hdr=yes;\""; 
       string ssqlconnectionstring = "server=ServerName;user id=sa;password=sa;database=Databasename;connection reset=false"; 
       //execute a query to erase any previous data from our destination table 
       string sclearsql = "Delete from " + ssqltable; 
       SqlConnection sqlconn = new SqlConnection(ssqlconnectionstring); 
       SqlCommand sqlcmd = new SqlCommand(sclearsql, sqlconn); 
       sqlconn.Open(); 
       sqlcmd.ExecuteNonQuery(); 
       sqlconn.Close(); 
       //series of commands to bulk copy data from the excel file into our sql table 
       OleDbConnection oledbconn = new OleDbConnection(sexcelconnectionstring); 
       OleDbCommand oledbcmd = new OleDbCommand(myexceldataquery, oledbconn); 
       oledbconn.Open(); 
       OleDbDataReader dr = oledbcmd.ExecuteReader(); 
       SqlBulkCopy bulkcopy = new SqlBulkCopy(ssqlconnectionstring); 
       DataTable dt = new DataTable(); 

       bulkcopy.DestinationTableName = ssqltable; 
       bulkcopy.WriteToServer(dr); 
       oledbconn.Close(); 

      } 
      catch (Exception) 
      { 
       throw; 
      } 
     } 



/*---------- call that file on buttonclick through OpenDialogBox--------*/ 

    private void button1_Click(object sender, EventArgs e) 
     { 
      DialogResult result = openFileDialog1.ShowDialog(); 

      if (result == DialogResult.OK) // Test result. 
      { 
       string strfilename = openFileDialog1.InitialDirectory + openFileDialog1.FileName; 
       importdatafromexcel(strfilename); 

      } 

      Console.WriteLine(result); 
      MessageBox.Show("Exported to SQL successfully"); 
     }
