This is equivalent to a newer ExprTrait::not and may require more some wrapping beforehand.

§Examples

let query = Query::select()
    .column(Char::SizeW)
    .from(Char::Table)
    .and_where(Expr::col(Char::SizeW).eq(1).not())
    .to_owned();

assert_eq!(
    query.to_string(MysqlQueryBuilder),
    r#"SELECT `size_w` FROM `character` WHERE NOT `size_w` = 1"#
);
assert_eq!(
    query.to_string(PostgresQueryBuilder),
    r#"SELECT "size_w" FROM "character" WHERE NOT "size_w" = 1"#
);
assert_eq!(
