如何显示涉及所有项目的ID（112933704400）

---

从Worknlist中选择ID，其中（完成所有1129、3370、4400的ID）

如果您知道项目的数量，则可以使用此选项：

select ID from workonlist
group by id
having count(distinct(projectNum))=3;

select ID from workonlist
group by id
having count(distinct(projectNum))=
            (select count(distinct(projectNum)) from workonlist);

或者，您可以使用：

select ID from workonlist
group by id
having count(distinct(projectNum))=3;

select ID from workonlist
group by id
having count(distinct(projectNum))=
            (select count(distinct(projectNum)) from workonlist);

select ID from workonlist

或者，您可以使用：

select ID from workonlist
group by id
having count(distinct(projectNum))=3;

select ID from workonlist

试试这个

select ID from workOnlist Where id IN(1129, 3370, 4400)

试试这个

select ID from workOnlist Where id IN(1129, 3370, 4400)

试试这个

select ID from workOnlist Where id IN(1129, 3370, 4400)

试试这个

select ID from workOnlist Where id IN(1129, 3370, 4400)
