Sending this again because I got no response the first time and didn't know if it was because I did something wrong protocol wise or if it was just because no one had any idea on what my issue could be.

If anyone has a link they can point me to in either case it would be greatly appreciated. I will keep searching as well.

Thanks

Hello All,

New to the list, so maybe an expert has the easy answer to this one...

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).

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 know I'm probably missing something simple but just don't know... they both seem to use the same InnoDB engine. I did notice the Db character set is different between the databases though (highlighted in blue below).

Maybe do I need to upgrade to MariaDB  10.4.14

Any help would be greatly appreciated.....?
