Trait Implementations

impl Clone for AlterStatement

fn clone(&self) -> AlterStatement

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AlterStatement

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

fn to_sql(&self) -> String

Convert the type to a SQL string.
