数据库的备份恢复是一个很重要的过程，下面用ASP.NET备份恢复SQL Server数据库。具体实现如下。
一、备份SQL Server数据库
| 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("<script language=javascript>alert('此文件已存在，请从新输入！');location='Default.aspx'</script>");return;}SqlCommand com = new SqlCommand(SqlStr2, con);com.ExecuteNonQuery();Response.Write("<script language=javascript>alert('备份数据成功！');location='Default.aspx'</script>");}catch (Exception error){Response.Write(error.Message);Response.Write("<script language=javascript>alert('备份数据失败！')</script>");}finally{con.Close();} |
二、还原SQL Server数据库
| string path = this.FileUpload1.PostedFile.FileName; //获得备份路径及数据库名称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("<script language=javascript>alert('还原数据成功！');location='Default.aspx'</script>");}catch (Exception error){Response.Write(error.Message);Response.Write("<script language=javascript>alert('还原数据失败！')</script>");}finally{con.Close();} |
