单个语句中的多个触发器 declarations/assignments

Question

我想声明几个触发器并在 单个脚本.

中将它们分配给多个表

示例：

create or replace function trigger_a()
returns trigger language plpgsql as $$
begin
    new.fetchname := new.name;
    return new;
end
$$;

create or replace function trigger_b()
returns trigger language plpgsql as $$
begin
    new.postname := new.name;
    return new;
end
$$;

create trigger trigger_a
create trigger trigger_b

before insert or update on tableFoo
for each row execute procedure trigger_a();

before insert or update on tableBar
for each row execute procedure trigger_b();

before insert or update on tableBaz
for each row execute procedure trigger_b();

运行以上抛出语法错误：

syntax error at or near "create"

Answer 1

这应该有效：

create or replace function trigger_a()
returns trigger language plpgsql as $$
begin
    new.fetchname := new.name;
    return new;
end
$$;

create or replace function trigger_b()
returns trigger language plpgsql as $$
begin
    new.postname := new.name;
    return new;
end
$$;

create trigger trigger_a
before insert or update on tableFoo
for each row execute procedure trigger_a();

create trigger trigger_b
before insert or update on tableBar
for each row execute procedure trigger_b();

create trigger trigger_b2
before insert or update on tableBaz
for each row execute procedure trigger_b();
