mysql查詢可以有兩個帶有2個IN子句的內部聯接嗎？

Question

我有4個不同的mysql表，

SELECT node.created AS node_created, node.nid AS nid, node.title AS title 
FROM node
INNER JOIN  field_data_field_resume_education ON field_data_field_resume_education.entity_id = node.nid
INNER JOIN 
    field_data_field_resume_of_study ON 
    field_data_field_resume_of_study.entity_id =
    field_data_field_resume_education.field_resume_education_value
INNER JOIN 
    field_data_field_resume_degree_level ON 
    field_data_field_resume_degree_level.entity_id =
    field_data_field_resume_education.field_resume_education_value 
WHERE  field_data_field_resume_degree_level.field_resume_degree_level_tid  IN (4,7) 
AND  field_data_field_resume_of_study.field_resume_of_study_tid IN (18,19,21) 
and (node.status = '1') 
AND (node.type IN  ('resume_content ')) 
GROUP BY nid 
ORDER BY node_created DESC

我試圖從2個不同的表中獲取值，以便IT僅返回兩個表中都存在的通用值，但它只返回一個空查詢。 我檢查了兩個都有一個共同的nodeid。

在where子句中可以有2個IN子句條件嗎？

請告訴我代碼有什么問題。

Answer 1

如果不是問題node.type IN（'resume_content'），則檢查另外兩個連接以及其中的所有條件，其中一個連接將失敗，例如連接field_data_field_resume_of_study.entity_id = field_data_field_resume_education.field_resume_education_value可能失敗。

您應該從一個表中執行select *，然后從一個表中選擇*，然后從一個表中選擇*，然后從一個表中選擇*，從第三個表中選擇*，然后從第三個表中選擇*，從另一個表中選擇第3個條件，在第1個條件下，您將很容易知道其失敗之處...
