Move data with schema change between MariaDB servers
I am tasked with the challenge to move data between two MariaDB servers. The source database is a MariaDB 5.x, and the destination database is a MariaDB 10.x. The problem is that I need to add a column to the target.
We are splitting a monolith service into microservices. The new database needs an additional column (found in a separate table in the source database).
Is the below the way to go or are there any nicer way of moving the data?
SELECT CONCAT("insert into table4(id,level,name,levelt2) VALUES(", quote(table1.id), ",", quote(table1.level), ",", quote(table2.name), ",", quote(table2.level), ");") as q
from table1 join table2 on table1.id = table2.table1_id
join table3 on table3.id = table2.table3_id
where table3.name in ('fee', 'fi', 'fo', 'fum');
cat query.sql|mysql --skip-column-names --raw > table4.sql
