Grammar or Syntax Description

• Brief description: The parser does not support specific features like ENCRYPTION, AUTO_INCREMENT, and ENGINE options in ALTER TABLE statements, categorizing them as UnspecifiedOperation. These features are part of MySQL-specific extensions to the ALTER TABLE syntax.

  ALTER TABLE confidential_data ENCRYPTION = 'Y';
  ALTER TABLE tt AUTO_INCREMENT = 101;
