    Description

      I've had the need for this few times already (e.g. Aria engine does that with the page checksum).
      It's a table attribute where the default value is not fixed, but set via a server variable. Like in

      SET SESSION opt_val=17;
      CREATE TABLE t1 ( .... ) opt_val=DEFAULT;
      CREATE TABLE t2 ( .... );
      CREATE TABLE t3 ( .... ) opt_val=10;

      for tables t1 and t2 the value of opt_val will be 17.

      Note that the value of opt_val is remembered when a table is created, later changes of the session variable don't affect the table.
