CREATE TABLE test_main(id int IDENTITY, if_id int, sortId int, primary key (id));

insert into test_main(if_id, sortId)values(2, 1);
insert into test_main(if_id, sortId)values(3, 1);
insert into test_main(if_id, sortId)values(2, 1);
insert into test_main(if_id, sortId)values(4, 1);
insert into test_main(if_id, sortId)values(4, 1);
insert into test_main(if_id, sortId)values(2, 1);

– 正常
select if_id, count(1) as count_t from test_main tm group by if_id having count(1) > 2;
– 错误
select if_id, count(1) as count_t from test_main tm group by if_id having count_t > 2
