  - Performing a user-variable assignment in a logical expression that is

  expression value to be used after the table is created, which causes the
  expression to be re-evaluated instead of accessing its value from the table.

  - An error in multiple invocations of a (1) prepared statement or (2) stored
  procedure that creates a query with nested JOIN statements.");
