备份SqlServer数据库
核心技术:
using System.Data.SqlClient;
using System.IO;
string SqlStr1 = "Server=(local);DataBase=master;Uid=sa;Pwd=";
string SqlStr2 = "Exec sp_helpdb";
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'";
1.前台
操 作 数 据 库
备份名称和位置
(如D:eifen)
2.后台
using System.Data.SqlClient;
using System.IO;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
string SqlStr1 = "Server=(local);DataBase=master;Uid=sa;Pwd=";
string SqlStr2 = "Exec sp_helpdb";
SqlConnection con = new SqlConnection(SqlStr1);
con.Open();
SqlCommand com = new SqlCommand(SqlStr2, con);
SqlDataReader dr = com.ExecuteReader();
this.DropDownList1.DataSource = dr;
this.DropDownList1.DataTextField = "name";
this.DropDownList1.DataBind();
dr.Close();
con.Close();
}
}
protected void Button1_Click(object sender, EventArgs e)
{
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();
}
}
}
还原SqlServer
核心技术:
string SqlStr1 = "Server=(local);database='" + this.DropDownList1.SelectedValue + "';Uid=sa;Pwd=";
string SqlStr2 = "use master restore database " + dbname + " from disk='" + path + "'";
