mysql - SQL 查询从选择查询的输出插入到特定列

Question

我有一个查询，如下所示:

select department as departmentname,count(distinct(uid)) as userscnt 
from outlier_report where department is not null group by department ;

我想将其插入到已经填充的 outlier_output 表中，该表有大约 20 个字段，包括部门名称和用户计数(该字段为空)。 我想将 select 输出中的 userscnt 字段放入 outlier_output 表中，其中 Department=outlier_report.department_name

我假设它会是这样的:

Insert into outlier_output(user_count Select department, count(distinct(uid) as userscnt from outlier_report where the department=outlier_report.departmentment_name)

确切的查询是怎样的？ 提前致谢

标准插入选择格式是:

INSERT INTO `tableA` ([field_list])
SELECT [results corresponding to items in the field list in the same order as the field list]
[etc...]
