When a table has an INVISIBLE column with a computed default, said default is only used in an INSERT if said column is not specified, but other columns are. Best illustrated with an example:

MariaDB> CREATE TABLE t1(c1 INT NOT NULL PRIMARY KEY, c2 INTEGER NOT NULL DEFAULT (c1 + 1) INVISIBLE);

MariaDB> INSERT INTO t1 VALUES(1),(2);

MariaDB> INSERT INTO t1(c1) VALUES(3),(4);

MariaDB> INSERT INTO t1 VALUES(5),(6);

MariaDB [test]> SELECT c1, c2 FROM t1;

+----+----+

| c1 | c2 |

+----+----+

|  1 |  0 |

|  2 |  0 |

|  3 |  4 |

|  4 |  5 |

|  5 |  0 |

|  6 |  0 |

+----+----+

As can be seen, when doing an INSERT without specifying the columns, 0 is inserted and the defined DEFAULT is ignored. If an INSERT specifying which columns to insert though, the DEFAULT is computed appropriately.
