Source

pub fn values<I>(&mut self, values: I) -> Result<&mut Self>
where I: IntoIterator<Item = Expr>,

    .values([

§Panics

Panics when number of values not matching number of columns. The equivalent insert_many method in SeaORM does not panic, it can construct the column list from active models.

§Examples
use sea_query::{tests_cfg::*, *};

let query = Query::insert()
    .into_table(Glyph::Table)
    .columns([Glyph::Aspect, Glyph::Image])
    .values_panic([2.1345.into(), "24B".into()])
    .values_panic([5.15.into(), "12A".into()])
    .take();

assert_eq!(
    query.to_string(MysqlQueryBuilder),
    r#"INSERT INTO `glyph` (`aspect`, `image`) VALUES (2.1345, '24B'), (5.15, '12A')"#
);
assert_eq!(
    query.to_string(PostgresQueryBuilder),
    r#"INSERT INTO "glyph" ("aspect", "image") VALUES (2.1345, '24B'), (5.15, '12A')"#
);
assert_eq!(
    query.to_string(SqliteQueryBuilder),
    r#"INSERT INTO "glyph" ("aspect", "image") VALUES (2.1345, '24B'), (5.15, '12A')"#
);
ⓘ
let query = Query::insert()
    .into_table(Glyph::Table)
    .columns([Glyph::Aspect])
    .values_panic([2.1345.into(), "24B".into()])
    .take();

The same query can be constructed using the raw_query! macro.

use sea_query::Values;

let values = vec![(2.1345, "24B"), (5.15, "12A")];
let query = sea_query::raw_query!(
    PostgresQueryBuilder,
    r#"INSERT INTO "glyph" ("aspect", "image") VALUES {..(values.0:1),}"#
);

assert_eq!(
    query.sql,
    r#"INSERT INTO "glyph" ("aspect", "image") VALUES ($1, $2), ($3, $4)"#
);
assert_eq!(
    query.values,
    Values(vec![2.1345.into(), "24B".into(), 5.15.into(), "12A".into()])
);

// same as above but with named fields:

struct Item<'a> {
    aspect: f64,
    image: &'a str,
};

let values = vec![
    Item {
        aspect: 2.1345,
        image: "24B",
    },
    Item {
        aspect: 5.15,
        image: "12A",
    },
];

let new_query = sea_query::raw_query!(
    PostgresQueryBuilder,
    r#"INSERT INTO "glyph" ("aspect", "image") VALUES {..(values.aspect, values.image),}"#
);

assert_eq!(query.sql, new_query.sql);
assert_eq!(query.values, new_query.values);
Source

pub fn values_from_panic<I, J>(&mut self, values_iter: J) -> &mut Self
where I: IntoIterator<Item = Expr>, J: IntoIterator<Item = I>,

Add rows to be inserted from an iterator, variation of InsertStatement::values_panic.

§Examples
use sea_query::{audit::*, tests_cfg::*, *};

let rows = vec![[2.1345.into(), "24B".into()], [5.15.into(), "12A".into()]];

let query = Query::insert()
    .into_table(Glyph::Table)
    .columns([Glyph::Aspect, Glyph::Image])
    .values_from_panic(rows)

assert_eq!(
    query.audit().unwrap().inserted_tables(),
    [Glyph::Table.into_iden()]
