Oh wait, I do. Notice that the keyword INTO was added here. This is optional and has no effect on MariaDB. It's only a matter of grammatical preference. In this example we not only name the columns, but we list them in a different order. This is acceptable to MariaDB. Just be sure to list the values in the same order. An INSERT statement takes priority over read statements (i.e., SELECT statements). An INSERT will lock the table and force other clients to wait until it's finished. On a busy MariaDB server that has many simultaneous requests for data, this could cause users to experience delays when you run a script that performs a series of INSERT statements',90000.00);
