Struct SingleRowInsert

pub struct SingleRowInsert<'a> { /* private fields */ }

A builder for an INSERT statement for a single row.

Implementations

impl<'a> SingleRowInsert<'a>

pub fn value<K, V>(&mut self, key: K, val: V)

where K: Into<Column<'a>>, V: Into<Expression<'a>>,

Adds a new value to the INSERT statement

let mut query = Insert::single_into("users");
query.value("foo", 10);

let (sql, params) = renderer::Postgres::build(query);

assert_eq!(r#"INSERT INTO "users" ("foo") VALUES ($1)"#, sql);
assert_eq!(vec![Value::from(10)], params);

pub fn merge(self, other: SingleRowInsert<'a>) -> Result<MultiRowInsert<'a>>

Merge two single row inserts into a multi row insert.

Both inserts must be to the same table and must include the same columns.

pub fn build(self) -> Insert<'a>

Convert into a common Insert statement.

Trait Implementations

impl<'a> Clone for SingleRowInsert<'a>

fn clone(&self) -> SingleRowInsert<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for SingleRowInsert<'a>

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

Formats the value using the given formatter.

impl<'a> From<SingleRowInsert<'a>> for Insert<'a>

fn from(insert: SingleRowInsert<'a>) -> Self

Converts to this type from the input type.

impl<'a> From<SingleRowInsert<'a>> for Query<'a>

fn from(insert: SingleRowInsert<'a>) -> Query<'a>

Converts to this type from the input type.

impl<'a> PartialEq for SingleRowInsert<'a>

fn eq(&self, other: &SingleRowInsert<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
