type Sum = Nullable<BigInt>

The SQL type of sum(this_type)

type Avg = Nullable<Numeric>

The SQL type of avg(this_type)

impl Add for SmallInt

type Rhs = SmallInt

The SQL type which can be added to this one

type Output = SmallInt

The SQL type of the result of adding Rhs to Self

impl Sub for SmallInt

type Rhs = SmallInt

The SQL type which can be subtracted from this one

type Output = SmallInt

The SQL type of the result of subtracting Rhs from Self

impl Mul for SmallInt

type Rhs = SmallInt

The SQL type which this can be multiplied by

type Output = SmallInt

impl SqlOrd for SmallInt

impl QueryId for SmallInt

type QueryId = SmallInt

A type which uniquely represents Self in a SQL query.

const HAS_STATIC_QUERY_ID: bool

HAS_STATIC_QUERY_ID: bool = true

Can the SQL generated by Self be uniquely identified by its type?

fn query_id() -> Option<TypeId>

Returns the type id of Self::QueryId if Self::HAS_STATIC_QUERY_ID. Returns None otherwise.
