ASP.NET中SQL Server數(shù)據(jù)庫備份恢復(fù)淺析
作者:佚名 
  SQL Server數(shù)據(jù)庫備份恢復(fù)對于編程人員來說是經(jīng)常碰到的問題,那么如何處理呢?我們將在本文中向你介紹處理SQL Server數(shù)據(jù)庫備份恢復(fù)的程序源碼。
 ASP.NET中SQL Server數(shù)據(jù)庫備份恢復(fù)的操作是如何的呢?首先我們來看看在ASP.NET中是怎么進(jìn)行SQL Server數(shù)據(jù)庫備份的。
以下是進(jìn)行SQL Server數(shù)據(jù)庫備份引用片段:
- string SqlStr1 = "Server=(local);
 - database='" + this.DropDownList1.SelectedValue + "';
 - Uid=sa;Pwd=";
 - string SqlStr2 = "backup database " +
 - this.DropDownList1.SelectedValue + " to disk='" +
 - this.TextBox1.Text.Trim() + ".bak'";
 - SqlConnection con = new SqlConnection(SqlStr1);
 - con.Open();
 - try
 - {
 - if (File.Exists(this.TextBox1.Text.Trim()))
 - {
 - Response.Write(" ");
 - return;
 - }
 - SqlCommand com = new SqlCommand(SqlStr2, con);
 - com.ExecuteNonQuery();
 - Response.Write(" ");
 - }
 - catch (Exception error)
 - {
 - Response.Write(error.Message);
 - Response.Write(" ");
 - }
 - finally
 - {
 - con.Close();
 - }
 
那么在ASP.NET中SQL Server數(shù)據(jù)庫備份之后我們會遇到恢復(fù)數(shù)據(jù)庫的操作,下面呢就是SQL Server數(shù)據(jù)庫備份恢復(fù)的源碼:
- string path = this.FileUpload1.PostedFile.FileName; //獲得備份路徑及數(shù)據(jù)庫名稱
 - string dbname = this.DropDownList1.SelectedValue;
 - string SqlStr1 = "Server=(local);
 - database='" + this.DropDownList1.SelectedValue + "';
 - Uid=sa;Pwd=";
 - string SqlStr2 = "use master restore database " + dbname + " from disk='" + path + "'";
 - SqlConnection con = new SqlConnection(SqlStr1);
 - con.Open();
 - try
 - {
 - SqlCommand com = new SqlCommand(SqlStr2, con);
 - com.ExecuteNonQuery();
 - Response.Write(" ");
 - }
 - catch (Exception error)
 - {
 - Response.Write(error.Message);
 - Response.Write(" ");
 - }
 - finally
 - {
 - con.Close();
 - }
 
ASP.NET中SQL Server數(shù)據(jù)庫備份恢復(fù)的相關(guān)內(nèi)容就向你介紹到這里,希望對你有所幫助。
