仅当当前字段存在于数组中时，如何对字段进行计数或求和

Question

我有以下查询：

SELECT 
count(form_rows.field_name), 
form_rows.field_name, 
sum(form_rows.field_value) as sales, 
form_Submissions.id as fsId 
FROM form_submissions
LEFT JOIN form_rows on form_Submissions.id = form_rows.form_submission_id
WHERE form_submissions.organization_id = 10
GROUP BY form_rows.field_name  

从而产生以下结果：

问题：有没有什么办法可以SUM和COUNT基于field_name

澄清：

说我有一个数组： ["ssn", "price"]

我只想总结在给定数组中存在field_names sales

Answer 1

这不是这样做的吗：

SELECT 
count(form_rows.field_name), 
form_rows.field_name, 
sum(form_rows.field_value) as sales, 
form_Submissions.id as fsId 
FROM form_submissions
LEFT JOIN form_rows on form_Submissions.id = form_rows.form_submission_id
WHERE form_submissions.organization_id = 10

AND form_rows.field_names in ('ssn','price')

GROUP BY form_rows.field_name
