Struct CreateTriggerStatement

    pub name: String,
    pub or_replace: bool,
    pub timing: TriggerTiming,

Expand description

v7.12.4 — CREATE [OR REPLACE] TRIGGER. Always row-level (FOR EACH ROW) in v7.12.4 — statement-level triggers parse but the executor refuses them. WHEN (cond) clauses are out of scope; the trigger function can short-circuit on a leading IF inside its body once v7.12.5 lands IF.

Fields§

§name: String§or_replace: bool§timing: TriggerTiming§events: Vec<TriggerEvent>

At least one event; INSERT OR UPDATE OR DELETE parses to three entries in order.

§table: String§for_each: TriggerForEach

FOR EACH ROW vs FOR EACH STATEMENT. v7.12.4 ships only Row; Statement parses but the executor refuses.

§function: String

Name of the function to invoke. v7.12.4 requires the function to be CREATE FUNCTION’d earlier; forward references (PG accepts) are deferred to v7.12.5.

§update_columns: Vec<String>

v7.13.0 — UPDATE OF col, col, … column-list filter (mailrs round-5 G7). Non-empty only when the events list contains UPDATE and the user wrote the column-list filter. PG fires the trigger only when at least one of these columns appears in the SET clause; SPG conservatively fires on any UPDATE matching the listed columns or rewriting them at the row level. Empty vec = no filter (fire on every UPDATE).
