Struct UpdateStatement

pub struct UpdateStatement { /* private fields */ }
Expand description

Update existing rows in the table

§Examples

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

let query = Query::update()
    .table(Glyph::Table)
    .values([(Glyph::Aspect, 1.23.into()), (Glyph::Image, "123".into())])
    .and_where(Expr::col(Glyph::Id).eq(1))
    .to_owned();

assert_eq!(
    query.to_string(MysqlQueryBuilder),
    r#"UPDATE `glyph` SET `aspect` = 1.23, `image` = '123' WHERE `id` = 1"#
);
assert_eq!(
    query.to_string(PostgresQueryBuilder),
    r#"UPDATE "glyph" SET "aspect" = 1.23, "image" = '123' WHERE "id" = 1"#
);
assert_eq!(

Implementations§

§

impl UpdateStatement

pub fn new() -> UpdateStatement

Construct a new UpdateStatement

pub fn table<T>(&mut self, tbl_ref: T) -> &mut UpdateStatement
where T: IntoTableRef,

Specify which table to update.

§Examples

See UpdateStatement::values

pub fn from<R>(&mut self, tbl_ref: R) -> &mut UpdateStatement
where R: IntoTableRef,

Update using data from another table (UPDATE .. FROM ..).

§MySQL Notes

MySQL doesn’t support the UPDATE FROM syntax. And the current implementation attempt to tranform it to the UPDATE JOIN syntax, which only works for one join target.

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

let query = Query::update()
    .table(Glyph::Table)
    .value(Glyph::Tokens, Expr::column((Char::Table, Char::Character)))
    .from(Char::Table)
    .cond_where(
        Expr::col((Glyph::Table, Glyph::Image))
            .eq(Expr::col((Char::Table, Char::UserData))),
    )
    .to_owned();

assert_eq!(
    query.to_string(MysqlQueryBuilder),
    "UPDATE `glyph` JOIN `character` ON `glyph`.`image` = `character`.`user_data` SET `glyph`.`tokens` = `character`.`character`"
);
assert_eq!(
    query.to_string(PostgresQueryBuilder),
    r#"UPDATE "glyph" SET "tokens" = "character"."character" FROM "character" WHERE "glyph"."image" = "character"."user_data""#
);
assert_eq!(
    query.to_string(SqliteQueryBuilder),
    r#"UPDATE "glyph" SET "tokens" = "character"."character" FROM "character" WHERE "glyph"."image" = "character"."user_data""#
);

pub fn values<T, I>(&mut self, values: I) -> &mut UpdateStatement
where T: IntoIden, I: IntoIterator<Item = (T, SimpleExpr)>,

Update column values. To set multiple column-value pairs at once.

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

let query = Query::update()
    .table(Glyph::Table)
    .values([
        (Glyph::Aspect, 2.1345.into()),
        (Glyph::Image, "235m".into()),
    ])
    .to_owned();

assert_eq!(
    query.to_string(MysqlQueryBuilder),
    r#"UPDATE `glyph` SET `aspect` = 2.1345, `image` = '235m'"#
);
assert_eq!(
    query.to_string(PostgresQueryBuilder),
    r#"UPDATE "glyph" SET "aspect" = 2.1345, "image" = '235m'"#
);
assert_eq!(
    query.to_string(SqliteQueryBuilder),
    r#"UPDATE "glyph" SET "aspect" = 2.1345, "image" = '235m'"#
);

pub fn value<C, T>(&mut self, col: C, value: T) -> &mut UpdateStatement

        (Glyph::Image, "24B0E11951B03B07F8300FD003983F03F0780060".into()),
    ])
    .to_owned();

assert_eq!(
    query.to_string(MysqlQueryBuilder),
    r#"UPDATE `glyph` SET `aspect` = 60 * 24 * 24, `image` = '24B0E11951B03B07F8300FD003983F03F0780060'"#
);
