UPDATE table SET col=val, … WHERE filter [WITH TTL duration] [WITH METADATA (…)]

Fields

table: String

Target table name

target: UpdateTarget

Explicit item-kind target. Omitted targets default to rows.

assignment_exprs: Vec<(String, Expr)>

Canonical SQL assignments.

compound_assignment_ops: Vec<Option<BinOp>>

Per-assignment compound operator for SET col += expr forms. None means ordinary SET col = expr.

assignments: Vec<(String, Value)>

Best-effort literal-only cache of assignments. Non-foldable expressions are preserved exclusively in assignment_exprs and evaluated later against the row pre-image by the runtime.

where_expr: Option<Expr>

Canonical SQL WHERE clause.

filter: Option<Filter>

Optional WHERE filter

ttl_ms: Option<u64>

Optional TTL in milliseconds (from WITH TTL clause)

expires_at_ms: Option<u64>

Optional absolute expiration (from WITH EXPIRES AT clause)

with_metadata: Vec<(String, Value)>

Optional metadata key-value pairs (from WITH METADATA clause)

returning: Option<Vec<ReturningItem>>

Optional RETURNING clause items.

order_by: Vec<OrderByClause>

Optional deterministic target ordering for limited UPDATE batches.

limit: Option<u64>

Optional LIMIT N cap. Caps the number of targets the executor will mutate in a single statement. Required by BATCH N ROWS data migrations (#37) which run the same UPDATE body in a loop, advancing a checkpoint between batches.

suppress_events: bool

Skip event subscription emission for this statement (SUPPRESS EVENTS).
