向大家介紹如何使用 ASP.NET 備份恢複 Sql Server 資料庫,大家可以做個參考,也希望對大家有所協助。 備份SqlServer資料庫:
以下是引用片段:
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();
}
還原SqlServer資料庫:
以下是引用片段:
string path = this.FileUpload1.PostedFile.FileName; //獲得備份路徑及資料庫名稱
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();
}
