Expand description

A builder for an INSERT statement for multiple rows.

Implementations§

Source§

impl<'a> MultiRowInsert<'a>

Source

pub fn values<V>(&mut self, values: V)
where V: Into<Row<'a>>,

Adds multiple new rows to be inserted.

let mut query = Insert::multi_into("users", vec!["foo"]);

query.values(vec![1]);
query.values(vec![2]);

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

assert_eq!(r#"INSERT INTO "users" ("foo") VALUES ($1), ($2)"#, sql);

assert_eq!(
    vec![
        Value::from(1),
        Value::from(2),
    ], params);
Source

pub fn extend(&mut self, other: SingleRowInsert<'a>) -> Result<()>

Extend the insert statement with a single row insert.

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

Source

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

Convert into a common Insert statement.

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

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