SQL：将视图连接到表以进行查询

Question

SELECT January.customer_id as Jancust_id,
           SUM(payments.payment) as Jan_cust_pmts,
           COUNT(DISTINCT January.customer_id) AS Jan_orig_cust,
           COUNT(DISTINCT payments.customer_id) as Jan_ret_cust,
           AVG(payments.payment) as Cust_life_rev
           January.acquisition_source as Jan_source
    FROM January_Cohort January
    LEFT JOIN telemon_payments_data payments
    ON January.customer_id = payments.customer_id
    GROUP BY Jan_source

所以上面应该是一个查询，其中January_Cohort是一个已经制作的视图，我想把它加入一个表telemon_payments_data。

我是指错了，还是我不能加入表格和观点？
错误消息是说January_Cohort不是表;我知道，这是一个观点。

可能会起作用 将视图作为子查询表

SELECT January.customer_id as Jancust_id,
           SUM(payments.payment) as Jan_cust_pmts,
           COUNT(DISTINCT January.customer_id) AS Jan_orig_cust,
           COUNT(DISTINCT payments.customer_id) as Jan_ret_cust,
           AVG(payments.payment) as Cust_life_rev
           January.acquisition_source as Jan_source
    FROM (select * from January_Cohort) January
    LEFT JOIN telemon_payments_data payments
    ON January.customer_id = payments.customer_id
    GROUP BY Jan_source
