H Andrei,

Thanks for the reply. To answer your question when I import the my_dump.sql (yes it does contain all 600 rows in that dump file) into a database on the MySQL server (which uses utf8 charset) then all works fine. All 600 rows are imported.

But when I used that same my_dump.sql file to import into a server running MariaDB then only 29 rows get imported. The MariaDB server is has latin1 as the default character set. So I tried to do an alter command on the specific database in question to change it's character set to utf8. When that did not work I dropped the database all together and re-created it using the utf8 database and that still did not work.

I run all the commands on the MariaDB server because I wanted to make sure the version of msyql or mysqldump was not the issue. Which it does not seem to be the issue since I can export and import remotely to the MySQL server just fine (from the MariaDB server)

    When I use mysqldump to backup a MySQL 5.7.8 database then import that database into a MariaDB
    10.4.8 database, at least one (maybe more) of the imported tables is missing rows. This is a
    WordPress database and the table in question is the wp_options table. I'm only getting 29 rows
    imported when there should be over 600 (in the original MySQL database).

Noted, 29 not 600.

   
    I'm using the mysqldump and mysql utilities located on the MariaDB server:
   
    mysqldump  Ver 10.17 Distrib 10.4.8-MariaDB, for Linux (x86_64)
    mysql  Ver 15.1 Distrib 10.4.8-MariaDB, for Linux (x86_64) using readline 5.1

    My steps as performed on the MariaDB server (the server I'm importing to).
   
    1. mysqldump -u username -pPassword -h remote_mysql_server database_name > wp_backup.sql
   
    2. mysql -u username -pPassword -h localhost database_name < wp_backup.sql

    When I run mysql (on the local MariaDB server) and import the wp_backup.sql to the
    remote_mysql_server everything works fine and all rows are importing into a test database out
    there:
   
    mysql -u username -pPassword -h remote_mysql_server database_name < wp_backup.sql
   
    So the above works

I am guessing it's 29 in 'all' of 'all rows are imported'.
Does 
  wp_backup.sql
actually have *all*  600?
