how export each table into separate file (DUMP)

Post by paul_huynh » Fri 16 Dec 2011 19:15

Please help. I recently downloaded a trial 30 days dotConnect for MySQL. I plan to buy it after trial expired. I am writing an web application (C#) to allow user backup and restore MySQL database. I don't know how to export each table into separate file while dumping it.
Please help. Thanks

I have created a little example that allows backing up each table to a different file. The sample backs up all the tables in the 'test' database.

Code: Select all

	    MySqlConnection conn = new MySqlConnection("Your connection string; database=test;");
            conn.Open();
            
            MySqlCommand comm = new MySqlCommand("show tables", conn);
            DataTable dt = new DataTable();
            MySqlDataAdapter da = new MySqlDataAdapter(comm);
            da.Fill(dt);

            MySqlDump dump = new MySqlDump();
            dump.Connection = conn;
            dump.Database = "test";

            string[] fileNames = new string[dt.Rows.Count];
            for (int i = 0; i < dt.Rows.Count; i++)
            {
                fileNames[i] = "D:\tempdir\file" + i.ToString()+".txt";
                dump.Tables = dt.Rows[i][0].ToString();
                dump.Backup(fileNames[i]);
            }
            conn.Close();
In my case, I have received 71 files in folder 'D:\tempdir'
