Struct Update 

pub struct Update {
    pub with: With,
    pub on_conflict: Option<ConflictAction>,
    pub target: FromTermId,
    pub assignments: Vec<(Vec<NameId>, ExprId)>,
    pub from: Vec<FromTermId>,
    pub filter: Option<ExprId>,
    pub returning: Vec<ResultColumn>,
    pub order_by: Vec<OrderTerm>,
    pub limit: Option<ExprId>,
    pub offset: Option<ExprId>,
    pub limited_at: Option<(Limited, Span)>,
}

An UPDATE statement.

Fields

with: With

The WITH prefix.

on_conflict: Option<ConflictAction>

The conflict algorithm from UPDATE OR ....

target: FromTermId

The target term, which carries its own alias and index hint.

assignments: Vec<(Vec<NameId>, ExprId)>

The SET assignments; a group of names is the (a, b) = ... form.

from: Vec<FromTermId>

An UPDATE ... FROM clause.

filter: Option<ExprId>

The WHERE clause.

returning: Vec<ResultColumn>

The RETURNING columns.

order_by: Vec<OrderTerm>

The ORDER BY, which SQLite allows with LIMIT.

limit: Option<ExprId>

The LIMIT.

offset: Option<ExprId>

The OFFSET.

limited_at: Option<(Limited, Span)>

Where the clause the reference build has no grammar for was written.

ORDER BY and LIMIT on a DELETE or an UPDATE are a compile-time option in SQLite, and the pinned build is not compiled with it - so the reference answers near "ORDER": syntax error and points at the word. The syntax register requires these to parse here, so the refusal is the binder’s; it needs the position to be able to point at the same word, and this is where the parser leaves it.
