Implementations

impl UpdateStatement

pub fn new() -> Self

Construct a new UpdateStatement

pub fn take(&mut self) -> Self

pub fn table<T>(&mut self, tbl_ref: T) -> &mut Self

where T: IntoTableRef,

Specify which table to update.

Examples

See UpdateStatement::values

pub fn from<R>(&mut self, tbl_ref: R) -> &mut Self

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::{audit::*, 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""#
);
assert_eq!(
    query.audit().unwrap().updated_tables(),
    [Glyph::Table.into_iden()]
