ASP.NET中SQL Server数据库备份恢复的操作是如何的呢?首先我们来看看在ASP.NET中是怎么进行SQL Server数据库备份的。
以下是进行SQL Server数据库备份引用片段:
- 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数据库备份之后我们会遇到恢复数据库的操作,下面呢就是SQL Server数据库备份恢复的源码:
- 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(" ");
- }
- catch (Exception error)
- {
- Response.Write(error.Message);
- Response.Write(" ");
- }
- finally
- {
- con.Close();
- }
ASP.NET中SQL Server数据库备份恢复的相关内容就向你介绍到这里,希望对你有所帮助。
